Question

我很难将oracle触发器转换为sql server。任何指针都非常感谢。我不知道如何更换＆＃34;如果插入那么＆＃34;和＆＃34;如果更新那么＆＃34;在sql server？

  create or replace trigger tg_ap
  before insert or update of strno, strfac, strfacstreet, strfacstreet2
  on AP
  for each row 
  begin 
  if inserting then
  :new.I_stat_ind:= 'Insert';
  end if;
   if updating then
      :new.I_stat_ind:= 'Update';
   end if;
   END;

在检测操作是更新，插入还是删除时，SQLServer使它变得有点棘手。

我不会写你的触发器，但这里有一些代码可以帮助你找出当前的操作：

Create Trigger [name] on [table] Before Insert, Update As
Begin
declare @actionId int    


select @actionId = case
                       when i.id is not null and d.id is     null then 1 -- insert
                       when i.id is not null and d.id is not null then 2 -- update
                       when i.id is     null and d.id is not null then 3 -- delete
                     end          
  from      inserted i full join deleted  d on d.id = i.id
