magento删除订单，本身没有这个功能，好像涉及到法律的问题，所以magento，没有这个功能，但是我们测试的订单，删除也费尽，

有一个插件，

http://www.magentocommerce.com/magento-connect/EMThemes.com/extension/4562/em_deleteorder/reviews，key：magento-community/EM_DeleteOrder，1.4.2不好用，看评论，1,4,1和1,。5没有问题！！但是我的版本是1.4.2，安装了不好用，不知道啥子原因！

另外一个插件安装了，可以删除，但是邮件收不到，

下面的是一个收费的订单插件：

不知道咋样，最后，还是用sql删除吧！！

通过下面的sql语句进行删除，删除前先备份：

After you have it executed, the test orders will not be in the database any more. Keep in mind that this willdelete ALL orders, in the database. So, you should execute this queries immediately after launch.
