I fail to see the logic behind his argument.
我不明白支持他论据的是什么逻辑。
If the row has changed, the UPDATE operation will fail and the application logic must handle the failure.
如果行发生了修改，UPDATE操作将失败，应用程序逻辑必须处理这一失败。
If the row does change, the update or delete will fail, and the application logic handles such failures by, for example, retrying the select.
如果确实对这一行进行了修改，那么更新或删除操作将会失败，应用程序逻辑将处理这些失败，例如，重新尝试选择。
