Because the DB Interface Module does not simulate behavior that is not provided in the MySQL C API and MySQL SQL grammar, certain functions of the DB Interface Module are reported as errors using the error code RWDBStatus::notSupported.

A broad range of errors can originate from the MySQL C library, the underlying network library, or the MySQL Server. These errors are reported using the error code RWDBStatus::serverError.

No attempt is made to mitigate against such errors, but when an error does occur, information is transferred to DB Interface Module objects as described below.
