Thread: regex_replace problem

Hi folks.

I've got a problem with regex_replace.  As you can see below psql displays the 
error saying the function does not exist.  Can anyone see why, and what I 
need todo to fix it.

Cheers

where ud_rfl ~ ' *= *';

Sorry,

should have added that I tried type-casting to see if that fixed it.  It 
didn't.

I think you lost a p in there.

The function is regexp_replace - you misspelled it.
