Error codeError messageReasonSolution
DB_ERROR_INVALID invalid SQL statment for preparing is not valid. See the prepare() documentation, if you want to use a SQL statement using placeholders.
DB_ERROR_MISMATCH mismatch Quantity of parameters didn't match quantity of placeholders in the prepared statment. Check that the number of placeholders in the prepare() statement passed to $query equals the count of entries passed to $params.
DB_ERROR_NODBSELECTED no database selected No database was chosen. Check the DSN in connect().
every other error code  Database specific error Check the database related section of the PHP-Manual to detect the reason for this error. In the most cases a misformed SQL statement. I.e. using LIMIT in a SQL-Statement for an Oracle database.
