Erik Darling tries something out:
I think it was sometime in the last century that I mentioned I often recommend folks turn on Forced Parameterization in order to deal with poorly formed application queries that send literal rather than parameterized values to SQL Server.
And then just like a magickal that, I recommended it to someone who also has a lot of problems with Local Variables in their stored procedures.
They were curious about if Forced Parameterization would fix that, and the answer is no.
Shot down by the third paragraph of the intro. That’s rough. Still, click through for the demo.
