在Insert语句的values部分中使用Case语句

Question

请原谅我的无知和糟糕的SQL编程技能，但我通常是一个基本的SQL开发人员。

我需要在一个表中插入数据时创建一个触发器，以便将不同的数据插入到另一个表中。

在这个触发器中，我需要根据来自原始表的新插入数据中的值将某些数据插入到新表中。这一点我完全搞不懂。我认为我应该有创意，在值部分使用case语句，但它不起作用。

有人能在这方面帮我一下吗？(下面是我目前所拥有的触发器的代码)

    INSERT INTO dbo.WebOnlineUserPeopleDashboard
    (
        ONLINE_USERACCOUNT_ID,
        ONLINE_ROOMS_DIRECTORY,
        ONLINE_ROOMS_LIST,
        ONLINE_ROOMS_PLACEMENT,
        ONLINE_ROOMS_MANAGEMENT,
        ONLINE_MAILINGLIST_DIRECTORY,
        ONLINE_MAILINGLIST_LIST,
        ONLINE_MAILINGLIST_MEMBERS,
        ONLINE_MAILINGLIST_MANAGER,
        ONLINE_PEOPLESEARCH_DIRECTORY
    )
