8.3.4 on Linux
Is there a way to regexp match on a null value? Or is it necessary to OR in a
or x is null?
Thanks in Advance !
Hey Dave,
Did you consider to use coalesce() ?

I would say no.
Or is it necessary to OR in a or x is null?
you could use a
COALESCE( text_column, '') ~ E'MyRegEx';
Or perhaps:
( text_column ~ E'MyRegEx'
!

Ya, I kinda knew about these approaches. The problem ahs to do with novice
users who don't know about coalesce or or;ing a check ofr nulls. I was
hoping there was some special regexp expression that would match
