Snowflake - Round Timestamps

Truncating or Rounding the Timestamps is useful for “grouping by time.” Following are 
some approaches:

DATA_TRUNC function
select date_trunc(‘second’ , now())

Predefined Functions in Snowflake

If we round by year, we can use the year() function (or month(), day(), week(), etc:

select year(getdate()) as year;
Round and Format the result as the string, e.g. ‘09-2021’
But, if we want to distinguish between the months of end years, we have to utilise 
“to_varchar()” function:
select to_varchar(getdate(), ‘mm-yyyy’);
select to_varchar(getdate(), ‘dd-mm-yyyy’);
select to_varchar(getdate(), ‘dd-mm-yyyy hh’);
select to_varchar(getdate(), ‘dd-mm-yyyy hh:mm’);
select to_varchar(getdate(), ‘dd-mm-yyyy hh:mm:ss’);
