Subject: [firebird-support] Soc Sec No comparison using Firebird
Greetings All,
I would like to pass into a stored procedure two social security numbers for comparison and have the result tell me if one character has changed, or if two characters were switched or if it does not compare at all.
Has anyone done anything like this they could share? Or is it even possible?
Thoughts?
Thanks,
Mike
