我有兴趣撰写一个触发点,它将忽视具体用户的询问,但对所有其他用户采取行动。 是否有办法这样做?
不过,一份说明:用户需要做一些询问,因此,我需要允许某些查询/删除/提盘。
如果你现在有一个触发点,即你不想火灾(我们在转移大量数据时就在审计触发点这样做),那么你可以在触发点开始时做这样的事:
if (suser_sname() = somename ) return
如果你想要做一些事情,那么你会做这样的事情:
if (suser_sname() = somename)
BEGIN
some code
END
ELSE
BEGIN
someother code
END
就此指出几个问题。 谨慎使用该守则,。 首先,如果你可以通过安全权利来做你所需要的,那就是一个更好的选择。 如果有人把自己的名字打成一个触发点的话,那么在你忘记了你在那里的时候,就会产生奇怪的结果。 如果你在短期内需要这样做(将1亿 000 000万份批量记录及时移至数据库,而不打上例如洗 au机),那么当项目完成时,就不要忘记加以改变。 你们不想审计某人的行动,特别是如果审计金融交易的话。 此外,在触发因素中做一些事情只会有助于插入/更新日期/模板。 我们不能阻止选择触发点。
仅仅调整他们的特权,使之不包含选择和你想要阻止他们做什么。
