我不认为他们实际上是在说删除数据不好，但他们没有提供删除表中所有数据的便捷方法，因为你可能会
在你打算键入时
意外调用以及这样做的后果这可能相当可怕。如果您确实想删除所有实例，则很简单：
这是您不太可能意外调用的内容
I don't think they're actually saying that deleting data is bad, but they don't provide a convenience method for deleting all data in a table, because it's possible that you might accidentally call

and the consequences of that could be fairly dire. If you really want to delete all instances, it's as simple as:
which is something you're unlikely to invoke accidentally
和唐一样，我同意他们并没有说这完全是坏事。
我阅读文档引用的方式是，在许多应用程序中，将记录标记为“隐藏”或“过期”而不是删除它，然后从显示/查询/等中删除它更合适。因此。这主要适用于需要历史数据保存或审计的应用程序。
该建议绝对是根据具体情况而定的，并且取决于您的应用程序的要求。
Like Don, I agree that they're not saying it's completely bad.
The way I read that documentation quote is that, in many applications, it's more appropriate to flag a record as "hidden" or "expired" instead of deleting it, and then remove it from displays/queries/etc. accordingly. This is mostly for applications that require historical data preservation or auditing.
The advice is definitely situational, and depends on the requirements of your application.
