Jose Manuel Jurado Diaz has a script for us:
During our last session in SQL Data Saturday, we received a question about if it is possible to know all the conversion implicit captured by Query Data Store. In the following example, I would like to share with you an example how to capture this considering among of SQL Antipatterns.
Basically, in sys.query_store_plan we found the column called query_plan that contains the text of the execution plan. With this information plus other Query Data Store DMVs we could see the information required.
Read on to see how you can shred out implicit conversions from the Query Store plans.
