lob->setBuffering -- Changes current state of buffering for large objectlob->setBuffering() sets the buffering for the large object, depending on the value of the on_off parameter. Repeated calls to lob->setBuffering() with the same flag will return TRUE. The values for on_off are: TRUE for on and FALSE for off.
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.
如果成功则返回 TRUE，失败则返回 FALSE。
