(no version information, might be only in CVS)lob->flush -- Flushes/writes buffer of the LOB to the server
Descriptionbool lob->flush ( [int flag])
lob->flush() actually writes data to the server. By default, resources are not freed, but using flag OCI_LOB_BUFFER_FREE you can do it explicitly. Be sure you know what you're doing - next read/write operation to the same part of LOB will involve a round-trip to the server and initialize new buffer resources. Tt is recommended to use OCI_LOB_BUFFER_FREE flag only when you are not going to work with the LOB anymore.
lob->flush() returns FALSE if buffering was not enabled or an error occurred.
如果成功则返回 TRUE，失败则返回 FALSE。
