Table 20-1. Possible PEAR_Error values
| Error code | Error message | Reason | Solution |
|---|---|---|---|
| DB_ERROR_INVALID | NULL | SQL statment for preparing is not valid. | See the prepare() documentation, if you want to use a SQL statement using wildcards. |
| DB_ERROR_NEED_MORE_DATA | NULL | Too few data for filling the prepared SQL statment. | Check the number of wildcards given in the SQL statement prepare(). Check the count of entries in the array for $params. The count of entries have to be equal to the number of wild cards. |
| DB_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 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. |
This function can not be called statically.
Note: query() can be used instead of prepare() and execute(), if you set the $params parameter and your query uses wildcards.
