OCILob::flush — Flushes/writes buffer of the LOB to the server
$flag = 0): boolOCILob::flush() actually writes data to the server.
flag
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.
成功时返回 true， 或者在失败时返回 false。
Returns false if buffering was not enabled or an error occurred.
