* Returns a boolean value indicating success.

* @param integer $pos Parameter identifier (for determining what to replace in the query).
* @param mixed $value The value to bind to the parameter.
* @param integer $type Explicit data type for the parameter using the PDO::PARAM_* constants. Defaults to PDO::PARAM_STR.
* @param integer $length Length of the data type. To indicate that a parameter is an OUT parameter from a stored procedure, you must explicitly set the length.
* @param mixed $driver_options
