RE: Conversion of a varchar2 to a number

Dave,

I inherited phone number fields where some of the records had chars in them and some did not (some were entered with '()' and '-', others were just numeric.

It was easy enough to create a function I called stripchars (str1, str2) which strips all occurences of any char in str2 out of str1. It may be faster to actually do a to_number and handle exceptions, I don't know. However, I've since found plenty of uses for the stripchars function.

If you want it I can send it to you.
