# db2_commit

(PECL)

db2_commit -- Commits a transaction

## 说明

bool db2_commit ( resource connection )

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`。
