AFAIK, MySQL has had support for a set-like type for a long time; as it has also had support for an ENUM type. Here are relevant documentation urls for 3.x thru 4.1, though I anticipate the later MySQL hasn't changed them much: http://dev.mysql.com/doc/refman/4.1/en/string-types.html http://dev.mysql.com/doc/refman/4.1/en/enum.html http://dev.mysql.com/doc/refman/4.1/en/set.html So these do exist, but I should point out that they are rather limited in functionality, and have certain caveats of use. Beware of using either ENUM or SET in numeric context, as what happens won't be what you expect; always use either in string context. You may be better off to use a related table instead for general purposes. -- Darren Duncan ------------------------------------------------------------------------- Take Surveys. Earn Cash.
