Question

请原谅我的无知和糟糕的SQL编程技巧，但我通常是一名基本的SQL开发人员。

我需要创建一个触发器，在一个表中插入数据，以将不同的数据插入另一个表中。

在此触发器中，我需要根据原始表中新插入的数据中的值将某些数据插入到新表中。我对这完全感到困惑。我认为我会很有创意并且在值部分中使用案例陈述但它不起作用。

有人可以帮我这个吗？（下面是我现在拥有的触发器的代码）

    INSERT INTO dbo.WebOnlineUserPeopleDashboard
    (
        ONLINE_USERACCOUNT_ID,
        ONLINE_ROOMS_DIRECTORY,

        ONLINE_MAILINGLIST_DIRECTORY,
        ONLINE_MAILINGLIST_LIST,
        ONLINE_MAILINGLIST_MEMBERS,
        ONLINE_MAILINGLIST_MANAGER,
        ONLINE_PEOPLESEARCH_DIRECTORY
    )
