Grant Fritchey is asking for input on a new flowchart he has created:
Lots of people are confused by how to deal with bad parameter sniffing when it occurs. In an effort to help with this, I’m going to try to make a decision flow chart to walk you through the process. This is a rough, quite rough, first draft.
I would love to hear any input. For this draft, I won’t address the things I think I’ve left out. I want to see what you think of the decision flow and what you think might need to be included. Click on it to embiggen.
I think it’s a great first step. I think a decision to add local variables and use them instead of parameters would be useful, particularly in contrast to using RECOMPILE and OPTIMIZE FOR UNKNOWN.
