If you want to get the distinct values in each field, you will need to do what John Hill said and SELECT DISTINCT fieldname from dbfor each field in questions. My way will give you all unique _combinations_ of the fields in question, not a single list of each columns unique values.If you normalize your database, you would have ItemType and ItemCat tables with a single record for each value. Then your main database would key into those tables for the values of each record. See any decent book on relational databases for details.John-- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4720 Boston Way Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5747------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list .
