My problem with Query Store and some of the people that use it is that, quite frequently, many of the plans (there's just 2 or there's more) are terrible. A lot of people think they're doing a good thing when, in reality, they forcing the best of two plans that are both terrible. Very few actually say, "This is a temporary patch... I'm opening a ticket to get it rewritten". 😉

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Thanks Prakash,

Though plan guides and pinning plans has been available in earlier versions, this exemplifies how much easier it is with querystore features in 2022. Thanks

Good article thank you. An important item to note > Microsoft Docs itselft mentions that forced plans are a temporary solution as a optimized plan today may not be the best plan tomorrow
