sql query not use index
Date: Mon, 9 Mar 2009 11:11:31 -0700 (PDT)
I was asked yesterday a project manager what sort of query will not
use an index?
What sort of index ? I asked
say a varchar(256) ?
A badly written regex. I responded.
Now I am worried I have given a misleading or wrong response! Can anyone help me out with a better answer?
