当要使用员工ID更新发布表的发布项目时，我想创建触发器。当我创建触发器时，这两个过程都会触发。但是我希望它用releaseItem触发。我该怎么办？

创建触发器CheckQty 库存更新一开始声明@qty int，@ emp int，@ q int，@ ItemId int

select @qty= qty, @emp=eid, @ItemId=ItemId
from inserted

select @q=qty
from Stock
where ItemId=@ItemId

if(@qty>0)
begin
    insert into releseItem
    values (@eid,@ItemId,@qty)
end
else
    rollback transaction
end

您可以按如下所示在触发器中执行存储过程。

create trigger CheckQty ON Stock for Update as begin declare @qty int, @emp int, @q int,@ItemId int
select @qty= qty, @emp=eid, @ItemId=ItemId
from inserted

select @q=qty
from Stock
where ItemId=@ItemId

if(@qty>0)
begin

    exec releseItem @eid, @ItemId, @qty

end
else
    rollback transaction
end

如何使触发器仅对特定SP做出反应
