How to declare a field for multiple values?

Last Modified: 2008-02-01
Hello all,

My database stores information on users.  There is an "interests" field for each user - sports, business, cars, movies, etc.  And they can select multiple interests.

In designing my database, I want to avoid having a separate field for each possible interest.  I want to have a separate Interests table that defines an ID for each interest, then store the selected interest IDs.  But - how to store them?  Ideally, they'd go in a single field, but there is no mysql data type that I know of that can store multiple values in a  single field.

I could append all the selected interest IDs in my program, the store the whole string in a single field, but that's clunky.

Is ther e a solution out there for me?
