ZF2 中的 ZendDb 如何控制事务? [英] How does ZendDb in ZF2 control transactions?

问题描述

ZF1 Zend_Db 参考手册有一个整个部分 关于执行交易.

The ZF1 Zend_Db reference manual has an entire section on performing transactions.

ZF2 ZendDb 参考手册缺少关于交易.

如何在 ZF2 中执行事务?示例代码会有所帮助.

How do I perform transactions in ZF2? Example code would be helpful.

推荐答案

缺少的文档很奇怪.

为了找出发生了什么，我不得不深入ZendDbAdapter 的 API 文档.

To find out what happened, I had to dive into the API docs for ZendDbAdapter.

看起来beginTransaction、rollback 和commit 都定义在ZendDbAdapterDriverConnectionInterface.这意味着它们是可在每个单独的适配器连接上调用的方法.不幸的是，连接本身被埋没了.

It looks like beginTransaction, rollback and commit are defined in ZendDbAdapterDriverConnectionInterface. This means that they are methods callable on every single adapter connection. Unfortunately the connection itself is rather buried.

我不清楚——目前无法提供一个例子——是弄清楚你实际上在哪个对象上调用了这些方法.在最坏的情况下，看起来您可能想要调用 $adapter->getDriver()->getConnection()->beginTransaction().

What I'm not clear on -- and can't provide an example for at this time -- is figuring out which object you actually call these methods on. In the worst case, it looks like you might want to call $adapter->getDriver()->getConnection()->beginTransaction().

呃.

我希望有更多知识的其他人以及手边的 ZF2 副本会看到这一点并提供更好的选择.

I'm hoping someone else with more knowledge, and a copy of ZF2 handy, will see this and provide a better option.

不要忘记你可以发出 BEGIN TRANSACTION/ROLLBACK/COMMIT/SET autocommit=... 自己的 SQL 语句.这可能没问题，因为它看起来不像 ZendDb 跟踪事务状态.

Don't forget that you can just issue BEGIN TRANSACTION/ROLLBACK/COMMIT/SET autocommit=... SQL statements yourself. This is probably OK, as it doesn't look like ZendDb keeps track of the transaction state.
