Good News Everybody!

Try looking at the plan cache. It’s highly likely that an old plan cache is still influencing the results.

Remove the plan cache and see if it clears the issue.

I know, I know, any change to the SQL etc should update the plan cache, but is adding an index without changing any of the other items in the SQL going to generate a new plan cache? Force a change, then review the results….

Not unusual....

It thinks the indexes would help, but can't know for sure until they exist.


I was under the impression that it recommends indexes based on the access
path's it has to create.

But, in retrospect, that doesn't make sense ... If it built a new access
path, that could take a massive amount of time.

Oh well.

Trust but verify.
