Method Question

[Andrew Sinning]

Is it possible to create a method (aka a "virtual" field) that is a
query of another table?

I have a table "questions":

	question_id  question  etc


and anthor table "question_categories" that is many to many

	question_id   category_id


I want to perform a single querry that will get me

	question_id  question  etc  Delimited_String_Of_All_Category_Ids



Any Suggestions?  Thanks
