OCI-Lob::flush()

(PHP 5, PHP 7, PECL OCI8 >= 1.1.0)

Flushes/writes buffer of the LOB to the server

说明

OCI-Lob::flush([int $flag]): bool

OCI-Lob::flush() actually writes data to the server.

参数

$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.

返回值

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.
