How can you view the Query Store settings for a database?

Question

I see that you can use notion like the following to set the query store configuration:

ALTER DATABASE <database name>   
SET QUERY_STORE (SIZE_BASED_CLEANUP_MODE = AUTO);  

But how can I check to see what the current value for SIZE_BASED_CLEANUP_MODE is?

Answer 1

This can be found (near the end) in the sys.database_query_store_options DMV.

SELECT size_based_cleanup_mode, size_based_cleanup_mode_desc
FROM sys.database_query_store_options
