Hi,
how can I remove a set of characters in text-columns ?
Say I'd like to remove { } ( ) ' " , ; . : !
Of course I can chain replace ( replace ( replace ( replace ( ... , ''
) .... and replace the chars one by one against an empty string ''.
There might be a more elegant way.
Is there ?
regards
Look at regexp_replace()
