How to write a Common Table Expression(CTE) in Snowflake

Write a Common Table Expression(CTE) in Snowflake

Common Table Expressions are the best way to divide the difficult queries. Snowflake also endorses this functionality.

Example for CTE:

with free_users1 as (
select *
from users1
where plan = ‘premium.’
)
select user_sessions . *
from user_sessions1
Inner join free__users1 on free_users1.id1 = user_sessions.user_id1
order by free_users1.id1;

Conclusion

Common Table Expressions are the subqueries specified in the “WITH” clause. Snowflake uses CTEs for separating queries. I hope this is sufficient for working with the CTEs.
