OCI-Lob->setBuffering — Changes current state of buffering for the large object
Sets the buffering for the large object, depending on the value of the on_off parameter.
Use of this function may provide performance improvements by buffering small reads and writes of LOBs by reducing the number of network round-trips and LOB versions. oci_lob_flush() should be used to flush buffers, when you have finished working with the large object.
TRUE for on and FALSE for off.
如果成功则返回 TRUE，失败则返回 FALSE。 Repeated calls to this method with the same flag will return TRUE.
