Re: How to clean up phone-numbers with regex?

Hi

I need to clean up phone-numbers. Somehow I got a Excel list that has weird graphical characters trailing some of the entries.
My DB is UTF8 so it would store this mess but I don't like to import it in the first place.

OK, I know how to read the stuff into a temporary table to clean it up before the actual import.
How can I do an update on the column that deletes every char that is not in a given set of chars like '+- 0123456/()'?


Second but similar question:
How can I select records that have fields that contain characters not included in a given alphabet?
E.G. find fields that contain some char not in 0-9,a-z,A-Z, +-()/?


regards
Andreas
