Error codeError messageReasonSolution
MDB_ERROR_INVALID NULL SQL statement handle is not valid. Check correct processing of the SQL statement with prepareQuery() . Note that executeQuery() requires a handle to the statement returned by prepareQuery() , not the statement itself.
MDB_ERROR_NEED_MORE_DATA NULL To less data for filling the prepared SQL statement. Check the number of wild cards given in the SQL statement for prepareQuery() . Check the count of entries in the array for $data. The count of entries have to be equal to the number of wild cards.
MDB_ERROR_NO_DB_SELECTED NULL No database was chosen. Check the DSN in connect() .
every other error code  Database specific error Check the database related section of PHP-Manual to detect the reason for this error. In the most cases a misformed SQL statement. Ie. using LIMIT in a SQL-Statement for an Oracle database.
