Mostly, the fact that it doesn't answer the OPs question, when it is perfectly It would be fairly simple to extend this to create the history tables and run a dynamic stored procedure in Snowflake to populate history using a Merge statement or implementing streams (CDC) within Snowflake. Check out our updated permissioning guidelines on the dbt Developer Blog for our modern recommendations. Generally, calling stored procedures like this from dbt is a hack: dbt runs should be idempotent, so if you are inserting or deleting data, etc. There are several IDEs (Integrated development environment) and plugins available to do Snowpark development in the local environment. This means that the procedure requires a wrapper such as in this example: {% macro output_message(return code) %} <Stored Procedure> call output_message(); {% endmacro %} If you are not calling the stored procedure from a Snowflake Scripting block, you cannot use the value returned by a stored procedure directly in SQL (unlike the value returned by a function). But rather than writing update, insert, temp tables, indexes, etc, you only write For a more granular check of those 4000 transactions we can check ch10_tbl or/and information_schema. dataset. Depends on the database used, but the idea is to wrap procedure creation in a macro. The stored procedure, named check_and_move_nulls_to_reject, dynamically addresses the issue of null values in any specified column of a table. This video provides insights into creating and managing stored procedures wit dbt is built on the assumption that your data transformations are idempotent – but what does that actually mean? And why was that design decision made? What is an idempotent data transformation?
