OCI-Lob->flush

(PHP 5, PECL oci8:1.1-1.2.4)

OCI-Lob->flush — Flushes/writes buffer of the LOB to the server

说明

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

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

如果成功则返回 TRUE,失败则返回 FALSE

Returns FALSE if buffering was not enabled or an error occurred.
