Thanks for the clarification, Marko.
I use ODBC 3.0, so it would seem that this is a bug.

Please check, but ODBC 3 should return SQL_NO_DATA, when
no data has been updated.
ODBC 2 should return SQL_SUCCESS wether any rows were updated, or not.
So it depends on the ODBC standard, that the client program chooses.
