Grant Fritchey shows us how to find a query in the Query Store:
The primary views you’ll want are sys.query_store_query and sys.query_store_query_text. They join together based on the query_text_id. Let’s take four scenarios and see if we can retrieve the correct query.
This is a little more complicated than I would have hoped, but as Grant notes, this is the CTP, so maybe there will be some tooling added to make life a little easier.
