Duplicate a Table in Snowflake

To duplicate a table, we have various methods. As per our intent, we will use the method. 

Copy both the data and table structure include:

Method1:

create table sessions1_copy clone sessions1;

Method2:

create table sessions1_copy as
select *
From sessions1;

Copy only specific columns into the fresh table along with the specific data set:

Create table sessions1_dm_2_copy as
select
id1,
start_date1,
end_date1
from sessions_dm_1
where category = 2;

Copy only specific columns from multiple tables into the latest table with specific data set:

create table users1_sessions12_rpt as
select*
u1.name,
s.start_date1 as session_start_date,
s.end_date1 as session.end_date1,
from sessions1 s
left join user_sessions us on s.id1 = us. session.id1
left join users_1 u on us. user_id1 = u.id1
where u1.active = true;

Copy only table structure, not data

create table users1_copy like users1;

Conclusion

Cloning the data objects will replicate the data, structure, and particular properties of source table. The cloned table will not have the loading history of source table. I hope this blog provides you with the information about Duplicating tables.
