# db2_commit

(no version information, might be only in CVS)

db2_commit -- Commits a transaction

## 说明

bool db2_commit ( resource connection )

警告
本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。

Commits an in-progress transaction on the specified connection resource and begins a new transaction. PHP applications normally default to AUTOCOMMIT mode, so db2_commit() is not necessary unless AUTOCOMMIT has been turned off for the connection resource.

> 注: If the specified connection resource is a persistent connection, all transactions in progress for all applications using that persistent connection will be committed. For this reason, persistent connections are not recommended for use in applications that require transactions.

## 参数

connection

  A valid database connection resource variable as returned from db2_connect() or db2_pconnect().

## 返回值

如果成功则返回 `TRUE`，失败则返回 `FALSE`。
