In the first article of this series, I discussed the Snowflake data type VARIANT, showed a simple example of how to load a VARIANT column in a table with a JSON document, and then how easy it is to query data directly from that data type.In this post I will show you how to access an array of data within the JSON document and how we handle nested arrays. Query below returns unused tables in a database what means tables which row count is equal to 0. It requires the right plan and the right tools, which you can learn more about by watching our co-webinar with Snowflake on ensuring successful migrations from Teradata to Snowflake.
