Truncating or Rounding the Timestamps is useful for “grouping by time.” Following are
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’);
Timestamps are essential to keep the records while information is created, exchanged, and deleted online. I hope this blog provides you with sufficient information about rounding the timestamp.
