How to Group by Time in Snowflake

Snowflake Group by Time

When we have to group the data by the hour, minute, week, day, etc., we can think that we can easily group it by our timestamp column.

If we do that, although, we will get one group per. Second -- possibly not what we require. Rather, we must “Truncate” our timestamp to the granularity we require, like day, hour, week, minute, etc. The function we require is “date_trunc():”

select
data_trunc(‘Day’ , start_date),
count(id) as number_of_sessions
from sessions
group by 2;

Conclusion:

By using “date_trun()” function we can truncate the timestamp to group the data by minute, week, day, hour, etc. I hope this blog is enough for grouping the data by time.
