Grant Fritchey takes us through an interesting scenario around Query Store:
This weekend I was in Stockholm in Sweden, talking Query Store and plan forcing with Steinar Anderson, when he mentioned the problems he had while forcing plans that had table variables in them.
Don’t panic. Of course you can force a plan with a table variable, most of the time. Steinar had a fairly focused problem. Before I go on to explain the issue, let me be really clear, Steinar figured out the issue all on his own. When he outlined the problem, I saw immediately what his conclusion was going to be. What’s spurring this blog post is that Steinar said he’d searched on the internet and no one had talked about the issue yet. So, let’s talk about it.
