Great post Kendra! I was particularly looking for the "Find queries using the index in Query Store", but running this one on a highly utilized with ~2 month of Query Store information took ~1h to run. I then copied Query Store tables to a different database and just once I created a full-text index on query_store_plan.query_plan column, it run pretty fast. What do you think or what's your experience with creating indexes (Full-text or non-clustered) directly on QS tables?

Loading... Reply Doug Lane February 22, 2017 2:16 pm I was thinking about how I was going to find all the queries using new indexes I deployed. I thought I might have to write a script and maybe blog about it, but there your post was when I googled the idea. You saved me the effort on both counts. Thanks, Kendra!

UPPER? Why?

Loading... Reply Dave May 17, 2019 8:29 am In each query plan returned, the index isn’t necessarily but appears in the OptimizerStats property as ‘%UsageStatistics=”[IndexName]”%’. Struggling to get around this. Any ideas?
Loading... Reply Kendra Little May 17, 2019 10:52 am Ahhhh — that makes sense. This script was written before OptimizerStats got added to the plan.
Should be able to do the filter with XQuery but I think you’re right about it being tricky. Maybe Erik Darling will write/blog this if he hasn’t already, I’ll tweet to him 😀
