Is this a changed stance for you?

PolicyID, guaranteed to NEVER be more than 10 characters, so the field was set to 10 characters (by the previous programmer). Guess what? We finally (3 years later) got a policed that was waaaay more than 10 characters. Of course the entire policy record could not go in, which prevented the claim from being processed. All users must get out of the database so that I can open up the field (to 255 characters of course). I don't care WHAT the business rule is, text data can and will change. SSN is a good example. It is guaranteed to be XXX-XX-XXXX except that they are running out of SSNs (50 years later) and guess what is going to change in the next few years... Length types of rules are not the thing (IMHO) that should be enforced at the DB level. John W. Colby www.ColbyConsulting.com
