Merges the SQL statment you submitted to prepare() with the information in $data and then sends the query to the database.

Error code | Error message | Reason | Solution |
---|---|---|---|
DB_ERROR_INVALID | invalid | SQL statment handle is not valid. | Check correct processing of the SQL statment with prepare(). Note that execute() requires a handle to the statement returned by prepare(), not the statment itself. |
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 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. |
Эта функция не должна вызываться статически.
Внимание |
The values passed in $data must be literals. Do not submit SQL functions (for example CURDATE()). SQL functions that should be performed at execution time need to be put in the prepared statement. |
