       for Update                          --为什么事件触发
     As                                        --事件触发后所要做的事情
       if Update(StudentID)
       begin

         Update BorrowRecord
           Set StudentID=i.StudentID
           From BorrowRecord br , Deleted   d ,Inserted i      --Deleted和Inserted临时表
