>Yes. Read up on check constraints. Thanks for everyone's suggestions and code. I'll go with the check constraint in this instance because 10-or-so lookup tables with 2-to-5 values in each that will never change seems like overkill. Plus, the other developer here isn't a fan of lookup tables where the range of values are known to be static and he'd shout at me ;-)
