Creating A Unique List With Table Query

Newbie question Hi Folks, I would like to be able to query a table, and return only the unique values from a particular field. For example: to get all contents from the category field from the contacts table: Query = .... SELECT Category FROM contacts But this will produce many duplicates. Question : How do I filter the query to only produce unique values? I was looking at: array_unique but I am not sure how to implement this in a MYSql table query.... Any help would be appreciated - thanks Dave -- Thanks - RevDave Cool @ hosting4days . com [db-lists 09]
