| Error code | Error message | Reason | Solution |
|---|---|---|---|
| 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. |
