Error code Error message Reason Solution
MDB_ERROR_INVALID NULL SQL statment for preparing is not valid. See the prepareQuery() documentation, if you want to use a SQL statemt using wildcards.
MDB_ERROR_NEED_MORE_DATA NULL To less data for filling the prepared SQL statment. Check the number of wild cards given in the SQL statment prepareQuery() . Check the count of entries in the array for $params. The count of entries have to be equal to the number of wild cards.
MDB_ERROR_NO_DB_SELECTED NULL No database was choosen. 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 statment. Ie. using LIMIT in a SQL-Statment for an Oracle database.
