In Snowflake, we use Common Table Expressions for dividing complex queries. Common Table Expressions(CTEs) define column names, query expressions, and a temporary view’s name. In this blog, you will learn to create Common Table Expressions.
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;
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.
