I am not aware of a UNIQUE clause in queries in SQL. There is DISTINCT to get the unique records, and MySQL has a UNIQUE constraint in CREATE TABLE and ALTER TABLE. Regardless, you may want to try rawQuery() instead of query() -- I tend to use that for things that are outside the ordinary. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android App Developer Books: http://commonsware.com/books.html --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
