Re: Using regular expressions in LIKE

Hi Terry,
thanks for your ansver. I've already read this page but I couldn't find out
if I can do such things or not. And if I can than how. So if you can suggest
me some additional manual pages regarding regular expressions can be used in
LIKE statements, please write me.

I don't know where to find it in the manual... :(

Thank you very much,
-- Csaba Együd
