The contribution of Salesforce in fulfilling the CRM needs of  organizations is invaluable. Since long back it has been a CRM global leader with its market share of 19.7%. As the growth of Salesforce is projected to be high, ultimately, the demand for the skilled Salesforce professionals would also be high.

We have collected a bunch of Salesforce interview questions and Salesforce scenario based interview questions which are sourced from Salesforce experts. I hope these questions would help you in cracking the Salesforce interview and landing in your dream job. If in case you have attended any Salesforce interview earlier and unable to find the same questions here, then feel free to comment those questions in the comment section, and we will update them in this blog, so that, it could help other students to learn from your experience.  Let's get into the QAs now.

 

1) What is meant by an object in Salesforce?

Objects in Salesforce are used as database tables that are used to store information of an organization.

We have two types of objects in Salesforce, which are:

Standard Object : these are the objects provided by the Salesforce which include Contacts, accounts, opportunities, leads, cases, campaigns, products, contracts, dashboards etc.

Custom Object : This includes the modifications made to the Salesforce by users. It stores the essential and unique information of an organization. Custom Object includes page layouts, relationship to other objects, custom user interface tab, custom fields etc.


2) What is App in Salesforce?

An App in Salesforce.com is a container which holds various things such as a logo, name, and a set of required tabs.  It is also called as a group of tabs that work together to prove the functionality that you are looking for.

In Salesforce, you can customize apps to match your requirements, or you can build new applications by combining custom and standard tabs.         

The process to create an app in Salesforce:

Setup ---> build---> Create---> App---> Click on new. By following this procedure you can build an application however you want.    


3) What is a profile? Can two users have the same profile?

The profile is defined as a collection of rules and procedures a person needs to follow to access particular records. There are multiple profiles available in Salesforce. For example, a sales profile can have access to leads, opportunities, contacts, campaigns, etc.

As far as the second question is considered the answer would be yes. The people who work in one department have the same profile. So the people whoever works under a particular department would be assigned with the same profiles.

As we have seen in the sales profile, many people work under it and every person works under is assigned with the same profile. Hence any number of people can have the same profile.   


4)  What are the benefits of using Salesforce CRM?

We get the following benefits by using Salesforce CRM.   

  • Improved organizational understanding.

Relationships in salesforce

6) What is the Master-Detail relationship?

This Master-Detail relationship is the same as the relationship between a parent & child. In this aspect, the master is treated as  Parent, and the Detail is a child. The master Object takes control over the behaviour of the Detail object. Survival of the child is dependent on the parent because if the Master get deleted the Detail will also automatically get deleted. You can create Roll-up summary fields in master records which helps in calculating the Min, Avg, Sum of the child records.

  • Developer
  • Developer pro
  • Partial copy
  • Full
10) Is it possible to edit visualforce page in production environment ?

  • To create Email services
  • Create web services
  • Perform complex validation over multiple objects
  • To create complex business processes that are not supported by workflow.
  • Create custom transaction logic
  • Attach custom logic to another operation
54) How Does Apex Work ?
  • All Apex programs runs entirely ON-Demand on Force.com Platform.
  • First the platform application server compiles the code into abstract set of instructions that can be understood by Apex runtime interpreter.
  • The compile code is stored to metadata.

When the end users triggers the execution of Apex by clicking button or visualforce page the application servers retrieves the compiled instructions from the metadata and send them to runtime interpreter before returning the result.

55) What is Apex Email Service ?

Email services is an automated process that use Apex classes to process the contents, Headers, Attachments of Inbound Email.

Note :

  • Visualforce email templates cannot be used for mass emails.
  • We can associate each email services with one or more salesforce generated email address to which the users can send messages for processing.
56) What is Map Class in Apex Salesforce ?
  • Map Class Contains methods for the Map collection type.
  • A Map is collection of key values pairs where each unique key maps to a single value.
  • Map keys and values can be any data type primitive types, collections, sObjects, users defined types, and built in Apex Types.

For Example, the following table represents a map of countries and currencies

Country(Key) ‘United States’ ‘Japan’ ;France’ ‘England’ ‘India’
Currency (Value) ‘Dollar’ ‘Yen’ ‘Euro’ ‘Pound’ ‘Rupee’
57) What is SOQL ?

A query language that allows you to construct simple but powerful query strings and to specify the criteria that should be used to select the data from the platform database. SOQL Stands for Slaesforce Object Query Language.

58) What Are The Types of SOQL Statements in SalesForce ?

Salesforce Object Query Language is used to query that records from the database.com based on the requirement.

There are 2 types of SOQL Statements.

1. Static SOQL

2. Dynamic SOQL

1 Static SOQL :

The oStatic SOQL Statement is written in []  (Array Brackets)

This statements are similar to IINQ(Ion Integrated Query)

Example:

String search for =’Jones’;

Contact[] contacts=[select testfield__c, FirstName, LastName from Contact Where Last Name=:search for];

2 Dynamic SOQL :

  • It is used to refer to the creation of a SOQL string at run time with Apex code.

  • Dynamic SOQL enables you to create more flexible application.

  • To create Dynamic SOQL query at run time use Database.Query() method, in one of the following ways.

  • Return a single sObjects when the query returns a single record.
    sObjects s = Database. Query(String_limit_l);

  • Return a list of sObjects when the query returns more than a single record.

Examples:

Eg 1 :

String myTestString = ‘TestName’;

List List= Database.Query(SELECT Id FROM MyCustomObject__c WHERE Name = :myTestString);

Eg2:

String resolviedfield L = myvariable.field__c;

List L = Database.Query(‘SELECT Id FROM myCustomObject__c WHERE field__c = ‘+resolvedfield_L);
59) What is The Syntax of SOQL Statement?

SELECT field1, field2,.... FROM Object_Type [WHERE condition]

Example:

List accountList =

   [SELECT ID, Name, FROM Account];

List accountList =

   [SELECT ID, Name, FROM Account WHERE annual revenue<10000];

60) What is Apex Interface ?

Interface is a collection of unimplemented methods. This will specify the signature of the method, types of inputs that we pass the method specifies what type is given as an output.

NOTE : Generally the interface methods we give it as global.

61) What is Batch Apex in Salesforce ?

Batch Apex :

Batch Apex allows you to define a single job that can be broken up into manageable chunks, whereas every chunk can be processed separately.

  • In the Batch Apex it will fetch all the records on which you want to perform the field update and divide them into list of 200 records and on every 200 records operation is performed separately.

  • This would help us to execute on more than 10,000 records as, it won’t perform an operation on all the records in a single transaction instead it dividing them into Number of subtasks where each subtask may contain the records up to 4000.

Example:

If you need to make a field update of every record of account object in your organization, then we have governing limits that would restrict us from achieving the above task.

Reason: In a single transaction we can process only 10,000 records. Now in the above case if we have more than 10,000 records in the organization then we can not perform this field update.

62) What is Apex Scheduler?
  • It will invokes the Apex class to run at specific time.

  • Anybody who want to schedule their class they have to implement schedulable interface.

Schedule Interface :

The class that implements this interface can be scheduled to run at different intervals. This interface has several methods they are

Public void execute(schedulablecontext sc)

Example:

Public class mySchedule implements schedulable

{

Public void execute(schedulablecontext sc)

{

Account a = new Account(Name = ‘Faraz’)

Insert a;

}

}

Triggers Are divided into 2 types

1. Before Triggers

2. After Triggers

Before Triggers :

Before Triggers can be used to update or validate values of a record before they are saved to the database.

After Triggers :

After Triggers Before Triggers can be used to access field values of the records that are the stored in the database and use this values to make changes in other records.

Syntax :

Trigger trigger_name on Object_Name(trigger_events) { Code_block } WHERE trigger_events can be comma separated list of events.
65) What is Apex Managed Sharing?
  • Apex Managed Sharing provides developers with the ability to support an application to share a requirements.

  • This type of sharing available to only users with modify all data permissions. Only this users can add/change apex managed sharing.

  • Apex Managed Sharing uses a Sharing reason (Apex Sharing Reason)

66) What is the Usage of apex program with within visualforce page ?

When you want to call apex class in visualforce page we have to declare in the following format.

< Apex : page controller = “class name “ >
  • Whenever we call  a visualforce page in which controller attribute is  defined it will first create an object for the apex class which is defined in controller.

  • Subscribe to our youtube channel to get new updates..!

    When object is created for the apex class first it involves the constructor.

67) GROUP BY ?

With  ApI version 18.0 and  later /you can use group by with aggregate functions, such as sum() or max() to summarize the data and enable you to rollup query results rather than having to process the individual records in your code.

 Syntax :

 [ GROUP BY field GROUP BY LIST]

68) SOSL Statements In Salesforce Apex ?

SOSL statement evaluate to a list of sobjects , where each list contains the search results for a particular sobject type, The result lists are always returned in the same order as they were specified in the query.

If a SOSL query does not return any records for a specified sObject type , the search results include an empty list for that sObject.

For example, you can return a list of accounts, contacts, opportunities and leds that begin with the phase map.

List < list < subject >> search list = [ find 'map*' In ALL FIELDS RETURNING Account (ID, Name), contact, opportunity, lead ];

Note :

  • The syntax of the classon Apex differs from the syntax of the FIND clause in the SOAP API.

  • In Apex, the value of the FIND cause is demarcated with single quotes.

Example:

FIND 'map*' IN ALL FIELDS RETURNING account (Id, Name], Contact, Opportunity, Lead.

In the Force.com API, the value of the FIND Clause is demarcated with braces.

For Example:

FIND {map*} IN ALL FIELDS RETURNING account  [Id,name], contact ,opportunity,lead.

From search list , you can create arrays for each object returned.

Account [ ]  accounts = (( list < accounts > ) search list [0] );

Contact [ ]  contacts = [( list ) search list [0]) ;

Opportunity [ ] opportunities = ((list < opportunity> ) search list [2]) ;

Lead [ ] leads = (( list < lead> ) search list [3]);
69) Javascript remoting for apex controllers ?

Use javascript remoting in visualforce to call methods in apex controllers from javascript.

Javascript remoting has 3 parts.

  • The remote method invocation you add to the visualforce page, written in javascript.

  • The remote method definition in your Apex controller class.

  • This method definition is written in apex, but there are  few differences from normal action methods.

  • The response handles callback function you add to or include in your vf page, written in javascript.

70) Adding javascript remoting to a vf page

To use javascript remoting in a vf page , add the request as a java script invocation with the following from.

[namespace.] controller.method (

                          [parameters….,]

                           Call back Function,

                         [configuration]

                      );
  • Name space is the namespace of the controller class

  • Controllers is the name of your apex controller.

  • Method is the name of your apex controller method you are calling.

  • Parameters is the comma-separated list of parameters that your method takes.

  • Callback function is the name of the javascript function that will handle the response from the controller.

  • Configuration configures the handling of remote call and response.

77) What are some apex classes that are commonly used within ?

Standard controller, select option, page reference, message, etc,

78) What are the effects of using the transient keyword?

The transient keyword prevents the data from being saved in to view state. This should be used for very temporary variables.                                                                 

79) Configuring javascript remoting requests ?

Configure a remoting request by proving an object with configuration settings when you declare the remoting request.

javascript remoting supports the following configuration parameters.

Name

Datatype

Description

Buffer

Boolean

Whether to group requests executed close to each other in time into a single request. The default is true.

80) How to invoke batch apex job (or) how to execute the batch apex job programmatically ?

We can use database.executebatch ( ) method to programmatically begin the batch job.

Syntax:

Public static ID execute batch ( sObject class name)

Public static ID execute batch (sObject class name, integes scope)

The above two methods are static methods of database class. We can use any one of the method to execute the batch job.

NOTE:

The class name what we are passing to the database.execute batch( ) method should be object of the class which has implemented database.batchable interface.

81) What is Future Annotation(@Future) ?
  • Use the future annotation to specify that these methods that are executed asynchronously.

  • Methods with future annotation must be static methods

  • Methods with future annotation can only return a void type.

{

@future

Static void methodname(parameters)

 {

//body of the method

}

Self Relationship is a lookup relationship to the same object. Suppose let’s take an object “Merchandise”. Here we can create relationship in between the Account to Account (same object) object. That is called “Self Relationship”.

90) What are the main things need to consider in the “Master-Detail Relationship”?

Record level access is determined by the parent, Mandatory on child for reference of parent, cascade delete (if you delete the parent, it can cascade delete the child).

91) What is the difference between trigger and workflow?

Workflow

  • Workflow is automated process that fired an action based on Evaluation criteria and rule criteria.

  • We can access a workflow across the object.

  • We cannot perform DML operation on workflow

  • We cannot query from database

Trigger

  • Trigger is a piece of code that executes before or after a record is inserted or updated.

  • We can access the trigger across the object and related to that objects

  • We can use 20 DML operations in one trigger.

  • We can use 20 SOQL’s from data base in one trigger.

92) What is Wrapper class?

A Wrapper class is a class whose instances are collection of other objects.

It is used to display different objects on a VF (Visual Force) page in same table.

93) Difference between SOQL Vs SOSL in salesforce?

SOQL- Salesforce Object Query Language

  • Using SOQL we can Search only on one object one time.

  • We can query on all fields of any datatype

  • We can use SOQL in the Triggers and the classes.

  • We can perform DML operation on sql query results.

SOSL (Salesforce object Search Language)

  • Using SOSL we can search on many objects at one time.

  • We can query only on fields whose data type is text,phone and Email.

  • We cannot use in Triggers but can in calsses.

  • We cannot perform DML operation on search results.

94) What is difference insert() and database .insert() ?

Using insert method we can insert the records but if any error occurs in any record system will throw an error insertion fail and none of the records are inserted.

If we want to execute partially success of bulk insert operation we will use database .insert.

95) What is Static Resources?

Using Static Resources we can upload images, zip files, jar files, javascript and CSS files that can be referred in a visual force page.

The maximum size of Static Resources for an organization is 250mB.

96) How to call javascript using Static Resource in Visual Force page?

Add java script file in Static Resource setup -> develop -> Static Resources -> click on ‘New’ -> Name: filename and add file from local desktop and save.

We can use that file as follows in Visual Force page

97) What is sharing rule?

If we want to give access to other users we use sharing rules.

98) How many ways we can share a record?

Role Hierarchy :

If we add a user to a role, the user is above in the role hierarchy will have read access.

Setup --> manage users --> roles --> setup roles --> click on ‘add role’ --> provide name and save.

OWD:

  • Defines the base line setting for the organization.

  • Defines the level of access to the user can see the other user’s record

OWD can be Private, Public Read Only, Public Read and Write.

Setup -> Security Controls -> sharing settings -> Click on ‘Edit’

Manual Sharing :

Manual Sharing is sharing a single record to single user or group of users.

We can see this button detail page of the record and this is visible only when OWD setting is private.

Criteria Based Sharing rules :

If we want to share records based on condition like share records to a group of users

Whose criteria are country is India.

Setup -> Security Controls -> sharing settings -> Click on ‘Edit’

Apex sharing :

Share object is available for every object(For Account object share object is AccountShare ). If we want to share the records using apex we have to create a record to the share object.

99) Unit testing code which has logic around the CreatedDate ?

You can create sObjects in memory with arbitrary CreatedDate values by using JSON.deserialize. This doesn’t enforce the normal read-only field attributes that prevent you from setting a createdDate value. However, you can’t commit arbitrary CreatedDate values to the database (or else it would be a serious security issue).

An example of doing so :

String caseJSON = ‘{“attributes”:{“type”:”Case”,”url”:”/services/data/v25.0/sobjects/Case/500E0000002nH2fIAE”},

“Id”:”500E0000002nH2fIAE”,

“CreatedDate”:”2012-10-04T17:54:26.000+0000″}’;

Case c = (Case) JSON.deserialize(caseJSON, Case.class );

System.debug(c.createdDate);

Note that I built the caseJSON string by creating a test case and serializing it, which is the easiest way to get JSON similar to what you want, then you can just tweak the values.

100) Ignoring Validation rules when deploying code ?

I have seen a solution that uses a Custom Setting of ValidationRuleEnabled.

ALL validation rules set up have the &&

$Setup.CustomSetting__c.ValidationRuleEnabled__c added.

  • When you want to deploy any code then the administrator changes the Custom Setting to FALSE, deploy the new code; don’t forget to re-enable the Custom Setting!

  • Again this is not ideal as the ‘legacy’ code should be updated to accommodate the new validation rules; ideally at the time of creating the new validation rules (but who checks code coverage after making a small change like a validation rule)

101) Can I find out if the current user has access to a record without querying ?

To find out if a particular user has Edit access to a record, use the UserRecordAccess object. This object is available in API version 24.0 and later. You can use SOQL to query this object to find out if the user has edit access to the record in question.

SELECT RecordId, HasEditAccess FROM UserRecordAccess WHERE UserId = [single ID] AND RecordId = [single ID]

If you want to check a batch of records you can use

SELECT RecordId FROM UserRecordAccess WHERE UserId=:UserInfo.getUserId()

AND HasReadAccess = true ANDRecordId IN :allRecordIds LIMIT 200

But make sure that allRecordIds is a LIST of IDs. It doesn’t work if allRecordIds is a SET of IDs. I guess that’s a bug.

Also, only a maximum amount of 200 recordIds can be checked in one query.

102) Detecting governor limits through apex ?

First of all, the exception thrown by hitting a limit, System.LimitException is uncatchable and means that your script will be killed, even if it happens inside a try/catch block. There is a class, Limits, that contains a number of static methods that allow you to check your governor limit consumption,

see: 

https://www.salesforce.com/us/developer/docs/apexcode/Content/apex_methods_system_limits.htm

With that said, your example of @future calls per day is one of the limits that simultaneously is and isn’t a governor limit as I believe it throws a System.AsyncException instead which  is not catchable, and kills your script as a LimitException would.

103) What is a concise function that formats a (String) decimal into a currency format in Apex ?

@RickMeasham’s method is a good one, but I ran into a couple rounding issues with negative values and fractional values. Here’s my edited version of the method that passes the tests I needed it to (not rendering -0.001 as “-0.00”, not rendering -1.10 as “-1.09”).

public static String formatCurrency(Decimal i)

{

if (i == null || Math.abs(i) < 0.005) return ‘$0.00’;

String s = (i.setScale(2) + (i >= 0 ? 0.001 : -0.001)).format();

return s.substring(0, s.length() – 1);

}

(EDIT: changed “<= 0.005” to “< 0.005” per @RickMeasham’s advice below.)

(EDIT 2: actually realized, when I finished tests, that this updated method still had a few shortcomings related to rounding. I updated to delegate to Math.roundToLong per code below [which uses round half even, not half up as I stated in my comments erroneously]. It now passes all my unit tests, which you can see here: https://codepad.org/ycttSXjq)

private String formatCurrency(Decimal i)

?{

if (i == null) return ‘0.00’;

i = Decimal.valueOf(Math.roundToLong(i * 100)) / 100;

String s = (i.setScale(2) + (i >= 0 ? 0.001 : -0.001)).format();

return s.substring(0, s.length() – 1);

}
104) How do you write a unit test for a trigger whose only function is to make a callout ?

Both future methods and callouts can be unit tested.

To test future methods simply make your call to any future method between Test.startTest();and Test.stopTest(); statements and the future method will return when Test.stopTest(); is called. See the documentation for the Test class here: System. Test

Testing callouts is a bit trickier though. Basically, in your callout code, you check to see if you’re executing within a unit test context by checking Test.isRunningTest() and instead of getting your callout response from an HttpResponse.send() request, you return a pre-built test string instead. There’s one example of this method here: https://www.iterativelogic.com/unit-test-callouts-in-apex-code-part-2/

There’s also an older example of callout unit testing that uses a static variable you set in your unit test. Just replace that static variable with a call to Test.isRunningTest() and their example works fairly well as well. That example can be found here:https://sfdc.arrowpointe.com/2009/05/01/testing-http-callouts/

105) Can report data be accessed programmatically?

Update for Winter ’14

API :

I think the biggest announcement that developers have been waiting for API wise is the availability of our Analytics API. We introduced a limited pilot in summer 13 and now the Analytics REST API is generally available. The Analytics API lets you integrate Salesforce report data into your apps programmatically and has several resources that let you query metadata, and record details.

Source – Winter 14 Developer Preview

106) How do you unit test a trigger when you don’t know the required fields ?

Customers can have validation on custom fields via validation rules and triggers, so handling that in your unit tests without customer intervention is next to impossible. The first step to reducing issues is to have your test data populate all standard fields and ensure the data uses the most common formatting for your customer base (US style phone numbers and addresses for the US for example).

Beyond that you can use the new Reflection features added to Salesforce in Summer ’12 to allow customers to create unit test data classes that can be used by your managed package. Basically you define a test data generation interface and the customer creates an Apex class to generate data for you. Here’s an example of using Reflection in a similar manner on the DeveloperForce blog:

https://blogs.developerforce.com/developer-relations/2012/05/dynamic-apex-class-instantiation-in-summer-12.html

Using the method for unit tests run on install might be problematic as you’d have to have the customer create the class before they install your package and your package could only look for the class by name (or iterate through all default namespace classes and check for the correct interface). However, it’s no longer necessary for unit tests to run during installation for managed packages and by default they do not.

The Reflection method requires some coding knowledge on the customer side, but you could add a tool in your application to generate the custom unit test data class for the customer.

FYI, it’s no longer necessary for managed package unit tests to succeed in customer orgs. They’re not required on install, they will no longer prevent deployment to production and they don’t count as part of the customers unit test coverage percentage for purposes of deployment. The only exception to that is if the customer uses ANT and sets the runAllTests parameter to true.

107) Deleting a class without IDE ?

This can be done with the Force.com Migration

Tool:https://wiki.developerforce.com/page/Force.com_Migration_Tool

See the full documentation here:

https://wiki.developerforce.com/page/Force.com_Migration_Tool

The tool can create or delete any meta-data that can be created through the Force.com IDE or Change Sets. It comes with a sample config file that contains example deployments for deploying objects and Apex code and deleting them as well. The documentation has a very detailed step-by-step guide here: https://www.salesforce.com/us/developer/docs/daas/index_Left.htm#StartTopic=Content/forcemigrationtool.htm

108) Is there a defacto 3rd party utilities library for Apex such as Apache Commons is for Java?

Apex-lang is about as close to a Java-style library as you can get. Contains several string, database, and collection utilities that mimmick Java functionality. Be aware though, some stuff including Comparing and Sorting collections is out of date with the advent of the Comparable interface in Apex.In addition to apex-lang, and like you suggest, I typically create or reuse static helper methods throughout my projects. Static helper methods are very convenient for reusing code in Chatter functionality, DML handling, Exception handling, Unit testing, etc.

109) Using transient keyword to store password in hierarchy custom setting ?

Because your myPref property is transient the initialisation you perform in the constructor won’t round trip when the page posts back.

When I’ve used transient and a protected custom setting I use separate properties that are transient and then only work with the custom setting in the post back method.

Controller

Skip code block

public with sharing class TestCustomSettings

{

// transient to ensure they are not transmitted as part of the view state

public transient String password1 {get; set;}

public transient String password2 {get; set;}

public PageReference save() {

// I’ve changed this to getInstance() rather than getValues()

TestR__c myPref = TestR__c.getInstance(UserInfo.getOrganizationId());

if(myPref == null) {

myPref = new TestR__c();

myPref.SetupOwnerId = Userinfo.getOrganizationId();

}

myPref.Password1__c = password1;

myPref.Password2__c = password2;

// Note that by using upsert you don’t need to check if the Id has been set.

upsert myPref;

}

}

Visualforce page

You can use inputSecret rather than inputField in the Visualforce page so that the browser will mask the input.

110) Is there a way to setup continous for apex tests ?

There are a couple of decent Dreamforce presentations here: Team Development: Possible, Probable, and Painless and Continuous Integration in the Cloud.

We ran into some issues with this in practice and there was no way to get true automation (i.e., set it and forget it). We were also set it up with Selenium.

Here were the issues that I remember.

Some features aren’t supported in the metadata API and cannot be moved via the ant migration. If you have any unit tests that work with those features, you have to manually work on your CI org.

Deletions are harder to maintain. You have to manually update and apply a destructiveChanges.xml file or replicate the deletion in the CI org.

We ran into a situation where some metadata XML files had ‘invalid’ data in them. The suggested solution was to build a post checkout script that manipulates the offending XMLs into valid XMLs. Not ideal.

On projects, we wanted to track just our changes and push out just our changes in source control. In theory, this would allow much easier rebaselining. This would have required more manual maintenance of XML files (e.g., 2 new fields added on Account and only want to push those 2 fields not all (*) fields).

My conclusion is that it is worth doing if you can get it set up, but if you are working on shorter-term projects and don’t have a decent amount of time budgeted in for it, it probably isn’t worth setting up. Although it isn’t CI, check out https://developer.force.com/cookbook/recipe/automated-unit-test-execution. You could set it up to run every hour or something like that.

111) What are the implications of implementing Database. Stateful ?

Daniel Ballinger: No, batches do not ever run simultaneously. You are correct, however, that serialization is the culprit here.

grigriforce: what’s your batch size? If you’re doing a million records, and your batch size is 1, then you will serialize/deserialize your state 1M times. Even with a small serialized object, that’s gonna hurt.

112) What are the recommended ways to refactor in Apex ?

I use the second method. After refactoring, I select the ‘src’ folder, use File Search/Replace and all the changes are made and saved to the server in one go.

113) What is a good set of naming conventions to use when developing on the Force.com platform ?

Follow the CamelCase Java conventions, except for VF pages and components start with a lower case letter.

Triggers:

  • Trigger – The trigger itself. One per object.

  • TriggerHandler – Class that handles all functionality of the trigger

  • TriggerTest

Controllers:

  • Controller

  • ControllerExt

  • ControllerTest

  • ControllerExtTest

Classes:

Test (These might be Util classes or Service classes or something else).

Visualforce pages and components:

[optionalDescription] (without the suffix Controller). There might be multiple views so could also have an extra description suffix.

Object Names and custom Fields

Upper_Case_With_Underscores

Variables/properties/methods in Apex

camelCaseLikeJava – more easily differentiated from fields

Test methods in test classes

test-For example, testSaveOpportunityRequiredFieldsMissing, testSaveOpportunityRequiredFieldsPresent, etc.

Working on something that would be used as an app or in some cases just a project? If yes, then do the following :

Prefix all custom objects, apex classes, Visualforce pages and components with an abbreviation so that they are easier to identify (e.g., easier for changesets). For example the WidgetFactory app would have the prefix wf on those. Additionally, when adding custom fields to a standard object they would also be prefixed to identify them as part of the app/package.

The main reason for the Object and Fields Names using Upper_Case_With_Underscores is that when you type in the name field or object with spaces it automatically adds the underscores. Although Apex is case insensitive, always refer to the Objects and Custom Fields in the code as Upper_Case_With_Underscores as well for consistency all around and consistency with what is generated by the SOQL schema browser and other tools. Object and Field Labels (which are generally ignored by code but visible to users) should keep spaces, not underscores.

114) Why use Batch Apex ?

A Batch class allows you to define a single job that can be broken up into manageable chunks that will be processed separately.

  • One example is if you need to make a field update to every Account in your organization. If you have 10,001 Account records in your org, this is impossible without some way of breaking it up. So in the start() method, you define the query you’re going to use in this batch context: ‘select Id from Account’. Then the execute() method runs, but only receives a relatively short list of records (default 200). Within the execute(), everything runs in its own transactional context, which means almost all of the governor limits only apply to that block. Thus each time execute() is run, you are allowed 150 queries and 50,000 DML rows and so on. When that execute() is complete, a new one is instantiated with the next group of 200 Accounts, with a brand new set of governor limits. Finally the finish() method wraps up any loose ends as necessary, like sending a status email.
  • So your batch that runs against 10,000 Accounts will actually be run in 50 separate execute() transactions, each of which only has to deal with 200 Accounts. Governor limits still apply, but only to each transaction, along with a separate set of limits for the batch as a whole.

Disadvantages of batch processing :

  • It runs asynchronously, which can make it hard to troubleshoot without some coded debugging, logging, and persistent stateful reporting. It also means that it’s queued to run, which may cause delays in starting.
  • There’s a limit of 5 batches in play at any time, which makes it tricky to start batches from triggers unless you are checking limits.
  • If you need access within execute() to some large part of the full dataset being iterated, this is not available. Each execution only has access to whatever is passed to it, although you can persist class variables by implementing Database.stateful.
  • There is still a (fairly large) limit on total Heap size for the entire batch run, which means that some very complex logic may run over, and need to be broken into separate batches.
115) Documenting Salesforce.com Apex class files ?

I have used apexDoc for a while and we are starting to roll it out more fully for our use at my organization. It is open source software and so you could always contribute some updates for it :-) What features are you wanting to add to it that it doesn’t have (just to give a flavor)?

In answer to your questions

1. I don’t think anybody has successfully managed to do this. There is an idea of the ideas exchange for it to be done but it seems to gain very little support.

2. Theoretically, it should be pretty easy as apex is a Java DSL. Have you tried running Doxygen and if so what errors does it throw up?

3. I use ApexDoc to generate some basic output and then have a little script tied in to copy across custom css and things. It isn’t perfect but it does for the small amount we need at the moment.

I believe the IDE is being open sourced at some time in which case I would imagine the antlr grammar file would become available which may help you out.

I know it is not really an answer for what you wanted to hear per se, but sadly it’s all we have atm (and I would love a nicer documentation generator!!)

116) Workarounds for Missing Apex Time.format() Instance Method ?

You could just split the DateTime format() result on the first space – does that give you what you’re looking for ?

public String myDateFormat(DateTime dt)

{

String[] parts = dt.format().split(‘ ‘);

return (parts.size() == 3) ? (parts[1] + ‘ ‘ + parts[2]) : parts[1];

}

produces

6:38 PM

for me in English (United States), and

18:42

in French(France).

UPDATE

As tomlogic points out, the above method is not very robust – some locales may include spaces in the date or time portion of the format, and the ordering is not consistent. This second attempt assumes that the date and time are separated by zero or more spaces, but handles spaces within the two portions, and either ordering of date and time. The only assumption made is that the formatted Date is contained within the formatted Time:

public String myDateFormat(DateTime dt)

{

return dt.format().replace(dt.date().format(), ”).trim();

}

Seems to work fine for Hebrew, Vietnamese & Korean, as well as English and French.
117)  Is there an average method for apex math ?

Unfortunately, the standard math methods only include simpler operations (i.e. those that work on a single, or two values), so it looks as though you’ll have to roll your own method.

Of course, the number of script statements executed will be proportional to the length of the list, so of the lists are ever of a fixed size it could be worth using a macro to generate the addition part for you:

Int sum = i[0] + i[1] + … i[n];

Doing so would only count for one statement, but you’ll only need this if governor limits are of concern which is often not a worry.

If govenor limits aren’t an issue you could create a function along these lines:

Skip code block

Integer[] myInts = new Integer[]{1, 2, 3, 4, 5, 6, 7};

Integer total = 0;

Double dAvg;

for (Integer i : myInts) {

total += i;

}

dAvg = Double.valueOf(total) / myInts.size();

return dAvg;

 

118) Grammar for creating an Apex parser ?

Keep an eye on Apex tooling api, which is used in Developer console. This is supposed to be released to public access soon.

119) Does ‘default value’ do anything if the object is created through Apex?

New feature coming in the next release:

Foo__c f = Foo__c.sobjecttype.newSObject(

recordTypeId, // can be null

true); // loadDefaultValues
120) Detect the current LoggingLevel in Apex ?

Unfortunately, I don’t think there is a way to check the current logging level in APEX.

121) Call Apex class method on the fly (dynamically) ?

While you can instantiate a class based on its name using the Type system class, you can’t dynamically locate a method and execute it. The best that you can do is to dynamically create an instance of a class that implements an interface and executes one of the methods on the interface.

There’s more information on the Type class and an example in the :

Apex Developer’s Guide

122) SOQL – query a query ?

It sounds like you’re talking about using nested SOQL queries. Here’s an example of querying a parent and two child objects in one query, using the relationship name for each related list of objects:

list accswithchildren = [select Id, Name, CreatedDate,

(select Id, CreatedDate from Tasks order by CreatedDate desc limit 1),

(select Id, Service_Date__c from Custom_Object__r order by Service_Date__c desc limit 1)

from Account where Id in :setofids];

You can then loop through those Accounts in Apex, and for each one, there is a list (size 0 or 1) of Tasks and Custom_Object__c:



for (Account a : accswithchildren)

{

list theseTasks = a.Tasks;

list otherobjects = a.Custom_Object__r;

//do something with these records

}
123) What’s the best way to check if person accounts are enabled via Apex Code ?

I’ve found two methods to accomplish this.

Method 1

Try to access the isPersonAccount property on an Account and catch any exception that occurs if that property is missing. If an exception is generated then person accounts are disabled. Otherwise they’re enabled. To avoid making person accounts required for the package you assign the Accountobject to an sObject and use sObject.get( ‘isPersonAccount’ ) rather than accessing that property directly on the Account object.

This method takes ~3.5ms and negligible heap space in my testing.

Skip code block

// Test to see if person accounts are enabled.

public Boolean personAccountsEnabled()

{

try

{

// Try to use the isPersonAccount field.

sObject testObject = new Account();

testObject.get( ‘isPersonAccount’ );

// If we got here without an exception, return true.

return true;

}

catch( Exception ex )

{

// An exception was generated trying to access the isPersonAccount field

// so person accounts aren’t enabled; return false.

return false;

}

}

Method 2

Use the account meta-data to check to see if the isPersonAccount field exists. I think this is a more elegant method but it executes a describe call which counts towards your governor limits. It’s also slightly slower and uses a lot more heap space.

This method takes ~7ms and ~100KB of heap space in my testing.

// Check to see if person accounts are enabled.

public Boolean personAccountsEnabled()

{

// Describe the Account object to get a map of all fields

// then check to see if the map contains the field ‘isPersonAccount’

return Schema.sObjectType.Account.fields.getMap().containsKey( ‘isPersonAccount’ );

}
124) Can’t Deploy Due to Errors in 3rd Party Packages ?
  • It was previously possible to install managed packages and Ignore APEX Test Errors this isn’t the case anymore.

  • You are probably going to have to uninstall them if you want to deploy from Sandbox to production and reinstall them.

  • If it’s Milestones PM (the package) is you can probably get an unmanaged version to work with and fix the bugs.

UPDATE

Looks like you are using the unmanaged package. So I think if you don’t want to uninstall before going to production your going to have to fix those errors manually by fixing the code.

Unfortunately, SFDC test methods don’t live in a complete vacuum where you can run tests against your org without bumping other code, even when you go to deploy.

125) How Can I Tell the Day of the Week of a Date ?

Formulas

There isn’t a built-in function to do this for you, but you can figure it out by counting the days since a date you know. Here’s the concept: I know that June 29, 1985 was a Saturday. If I’m trying to figure out the day of the week of July 9 of that year, I subtract the dates to determine the number of days (10), and then use modular division to figure to remove all the multiples of 7. The remainder is the number of days after Saturday (1 = Sunday, 2 = Monday, etc.) and you can use that number in your logic:

MOD(DATEVALUE( Date_Field__c ) – DATE(1985,7,1),7)

Apex Code

You could do the same thing with time deltas, but you can also use the poorly

documentedDateTime.format() function:

Cast the Date variable into a DateTime

DateTime myDateTime = (DateTime) myDate;

String dayOfWeek = myDateTime.format(‘E’);

// dayOfWeek is Sun, Mon, Tue, etc.

126) What is App in Salesforce?

An app is a group of tabs that work as a unit to provide functionality. Users can switch between apps using the Force.com app drop-down menu at the top-right corner of every page.

You can customize existing apps to match the way you work or build new apps by grouping standard and custom tabs.

Navigation to create an app in Salesforce: Setup ->Build ->Create->App-> Click on new and create your application according to your requirements.

127) What is the object in Salesforce.com?

Objects are database tables that allow you to store data specific to your organization in salesforce. You can use custom objects to extend salesforce.com functionality or to build new application functionality.

When you create a custom object, we can create a custom tab, customized related lists, reports, and dashboards for users to interact with the object data. You can also access custom object data through the Force.com API.

Navigation to create an object in sales force: Setup-->Build-->Create-->Object--> Click on new object and create object according to your requirement.

128) How many relationships included in SFDC & What are they ?

We are having two types of relationships, they are

  • Lookup Relationship

  • Master-Detail Relationship

129) What is a “Lookup Relationship ?

This type of relationship links two objects together,

  • Up to 25 allowed for object

  • Parent is not a required field.

  • No impact on a security and access.

  • No impact on deletion.

  • Can be multiple layers deep.

  • Lookup field is not required.

[Related Page: How to Create Field Dependence in SalesForce]

130) What is “Master-Detail Relationship”?

Master-Detail relationship is the Parent-child relationship. In which Master represents Parent and detail represents Child. If Parent is deleted then Child also gets deleted. Roll-up summary fields can only be created on Master records which will calculate the SUM, AVG, MIN of the Child records.

  • Up to 2 allowed to object.

  • Parent field on child is required.

  • Access to parent determines access to children.

  • Deleting parent automatically deletes child.

  • A child of one master detail relationship cannot be the parent of another.

  • Lookup field on page layout is required.

131) How can I create Many – to – Many relationships?

Lookup and Master-detail relationships are one too many relationships. We can create many – to – Many relationships by using a junction object. Junction object is a custom object with two master-detail relationships.

132) A custom object contains some records, now my requirement is to create a field in this object with master-detail relationship. Can we create master-detail relationship in this case?

No, directly we cannot create master-details relationship if a custom object contains existing records.

Following are the steps to create to create a master-detail relationship when records are available in a custom object.

First create field with lookup relationship.

And then associate look field with parent record for every recordNext change the data type of the field from look up to Master detail.

133) List examples of custom field types ?

Text, Pick list, Pick list (multi select), Date, Email, Date/Time, Date, Currency, Checkbox, Number, Percent, Phone, URL, Text Area, Geolocation, lookup relationship, master detail relationship etc…..

134) What is TAB in Salesforce?

Tab is a user interface component to user creates to display custom object data.

There are three type of tabs.

  • Custom Tabs

  • Visual force Tabs

  • Web Tabs

135) What are the actions in workflow ?
  • Email Alert

  • Task

  • Field Update

  • Outbound Message
