No, it isn't. It would be too slow. Default value is returned by select if no field value exists in returned record version. Engine works about this way: 1) Prepare buffer for returned values and fill it with default values. 2) Replace values in the buffer with values extracted from storage. 3) Send the buffer to client side. -- WBR, SD. ------------------------------------ ------------------------------------ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Visit http://www.firebirdsql.org and click the Documentation item on the main (top) menu.
