Please be specific on what you would consider correct. I'm not recalling
any details of past discussions so need some background.
I see mention in my SQL99 docs of escape characters for "similar
pattern" which would suggest that it resembles Posix regexp matching. I
don't have the code in front of me to check on the details of the
current implementation, but I'd hope that you have something helpful to
say on what a better implementation would be.
Regards.
