低于触发应该努力-
它也可能与检查约束要做到这一点，但在所示的逻辑这个帖子样的伤害了我的头上。

CREATE TRIGGER [dbo].[DateRangeTrigger]
   ON  [dbo].[TargetTable]
   FOR INSERT, UPDATE
AS 
BEGIN

IF EXISTS (SELECT t.starttime, t.endtime FROM TargetTable t
        Join inserted i
        On (i.starttime > t.starttime AND i.starttime < t.endtime AND i.UniqueId <> t.UniqueId) 
           OR (i.endtime < t.endtime AND i.endtime > t.starttime AND i.UniqueId <> t.UniqueId)
           OR (i.starttime < t.starttime AND i.endtime > t.endtime AND i.UniqueId <> t.UniqueId)
        )
BEGIN
    RAISERROR ('Inserted date was within invalid range', 16, 1)
    IF (@@TRANCOUNT>0)
        ROLLBACK
END


END
