select distinct with all columns

I have a mysql table named "equipment" with 11 columns named: id, staff_member, class, type, manufacturer, model, description, picture, created, modified, and published. I'm trying to write a select statement similar to this: SELECT DISTINCT type FROM equipement WHERE class = "microphones"; yet shows all 11 columns of the selected rows rather than just the type column. The only way I know how to show all the columns is to use SELECT *, or to list all the columns manually like "SELECT id, type, class, ... etc." But when I tried doing this: SELECT DISTINCT type, id, staff_member, class, manufacturer, model, description, picture, created, modified, published FROM equipment WHERE class = "microphones"; I just got the exact same answer as if i would have done this: SELECT * FROM equipment WHERE class = "microphones"; so it didn't help. Can anyone offer a hint? Thanks, russ
