Validating a Social Security Number [message #7354]

I have a variable (SSN_NUM) declared as VARCHAR2(15). I would like to validate this variable to confirm it only contains numbers 0-9. Is there a built-in that would do this?

Thanks!!
Mel

replace(translate(ssn_num, '0123456789', '0'), '0') is null

indicates only numbers. Change to IS NOT NULL to identify any values with non-numerics.
