Thanks for your help :) : TTable : function FindKey(const KeyValues: array of const): Boolean; (success = true) Use this to check whether or not the key(s) already exist. Obviously if it does then its gonna be a duplicate record (do this before post). Out of interest TDataset generates exception EKeyViolation when theres a duplicate key.
