## 例

`

     mixed odbc_autocommit ( resource $connection_id [, bool $OnOff = false ] )

`

## 説明

Toggles autocommit behaviour. By default, auto-commit is on for a connection. Disabling auto-commit is equivalent with starting a transaction.

## 戻り値

Without the OnOff parameter, this function returns auto-commit status for connection_id. Non-zero is returned if auto-commit is on, 0 if it is off, or FALSE if an error occurs. If OnOff is set, this function returns TRUE on success and FALSE on failure.
