  • MySQL has enums to save space (and thus improve speed), not to enforce values. For that, you should use a lookup table and a foreign key, like you would with Oracle. (Constraints are a lousy place to put a list of acceptable values because they are hard to edit from user apps.) Or you could run the database in "traditional" mode, which should make it throw an error for data that doesn't fit in an enum. Personally, I just avoid enums and use lookup tables, except for data warehouse situations where I have tight control over how the data gets into the table.
