SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_NEED_DATA, SQL_STILL_EXECUTING, SQL_ERROR, SQL_NO_DATA, SQL_INVALID_HANDLE, or SQL_PARAM_DATA_AVAILABLE.

When SQLExecute returns either SQL_ERROR or SQL_SUCCESS_WITH_INFO, an associated SQLSTATE value can be obtained by calling SQLGetDiagRec with a HandleType of SQL_HANDLE_STMT and a Handle of StatementHandle.

ret = SQLGetDiagRec(SQL_HANDLE_STMT, stmt, 1, sql_state, &native_error, message, sizeof(message), &msg_len)

But even that is returning -2 and not giving any other details, hence I commented it. Am I missing anything? How can I get more details from ret object apart from -2.
