This wouldn't be posible either, because the argument for Distinct is tip, so other fields will be ignored. But simply it can't retrieve id. If i want to retrieve it also, it returns zero fields. Thank you anyway. Regards, Marius Panaitescu DC> Very odd. I would think it would return every record seeing DC> as the auto_increment ID field is different for every record. >>>I use "SELECT DISTINCT tip, marca, model FROM modele" to select >>>records without duplicates on the field "tip". This works ok, BUT if I >>>use "SELECT DISTINCT tip, marca, model, id FROM..." (id is >>>auto_increment and is the table's primary key) my query won't produce >>>any result. ANyone has a clue?
