                                    throws java.sql.SQLException
        Send a resultSet that contain auto generated keys. 2 differences :
        1. Batch will list all insert ids.
        2. in case of multi-query is set, resultSet will be per query.

        example "INSERT INTO myTable values ('a'),('b');INSERT INTO myTable values ('c'),('d'),('e')" will have a resultSet of 2 values, and when Statement.getMoreResults() will be called, a Statement.getGeneratedKeys will return a resultset with 3 ids.

        Parameters:
        protocol - current protocol
        Returns:
        a ResultSet containing generated ids.
        Throws:
        java.sql.SQLException - if autoGeneratedKeys was not set to Statement.RETURN_GENERATED_KEYS
