Snowflake countif.
Although snowflake would possibly allow that (as demonstrated by Gordon Linoff), I would advocate for wrapping the aggregate query and using window functions in the outer query. Few RDBMS allow mixing window functions and aggregation, and the resulting queries are usally hard to understand (unless you are an authentic SQL wizard like Gordon!).

The TB_TRANSFERRED can be found in one query above. These are the terabytes transferred during the specified time.The 20$ is the price for transferring 1 TB of data within 2 different regions of AWS cloud.Then the row count is used to make certain decision to continue execution or abort it. Snowflake scripting provides system variables that hold the information of records affected by an INSERT, UPDATE or DELETE queries in the current session. In this article, we will check how to get rows affected by last Snowflake SQL Query.
