參考例子

首先先通過coroutineBegin獲取到id。

然后在使用的到事務的coroutineSend方法中第一個參數填寫此id。

最后記得執行coroutineCommit或者coroutineRollback。

```php
$transaction_id = yield $this->mysql_pool->coroutineBegin($this);

$update_result = yield $this->mysql_pool->dbQueryBuilder->update('user_info')
						->set('sex', '1')
                        ->where('uid', 10000)
                        ->coroutineSend($transaction_id);
                        
$result = yield $this->mysql_pool->dbQueryBuilder->select('*')
				->from('user_info')
                ->where('uid', 10000)
                ->coroutineSend($transaction_id);
                
if ($result['result'][0]['channel'] == 1000) {
    $this->http_output->end('commit');
    yield $this->mysql_pool->coroutineCommit($transaction_id);
} else {
    $this->http_output->end('rollback');
    yield $this->mysql_pool->coroutineRollback($transaction_id);
```
