CitectSCADA SQL devices and Cicode functions also use the ODBC functions listed in the table below. While these functions are not necessary for operation, if they are absent in a driver, the error code 307 (SQL database error) will be returned if the ODBC driver does not support the necessary ODBC functions. To get the message associated with the error, call the Cicode function SQLErrMsg.
