OCI-Lob->flush -- Flushes/writes buffer of the LOB to the server
说明
class
OCI-Lob {
bool
flush ( [int flag] )
}
OCI-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. It is recommended to use
OCI_LOB_BUFFER_FREE flag only when you are not going
to work with the LOB anymore.
OCI-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。
