sqlserver 2008 触发器，对象名 'dbo.inserted' 无效？解决方案

sqlserver 2008 触发器，对象名 'dbo.inserted' 无效？？？
建了一个触发器
if exists (select 1
  from sysobjects
  where id = object_id('T_accountingsubject')
  and type = 'TR')
  drop trigger T_accountingsubject
go


if exists(select 1 from inserted) and not exists(select 1 from deleted)
begin
  update accountingsubjects set isend=0 where id in(select parentid from inserted)
end
go

执行时提示
消息 208，级别 16，状态 1，第 3 行
对象名 'dbo.inserted' 无效。


这是怎么回事，难道2008没了inserted 和deleted表？


------解决方案--------------------

SQL code

if exists (select 1
  from sysobjects
  where id = object_id('T_accountingsubject')
  and type = 'TR')
  drop trigger T_accountingsubject
go
create trigger T_accountingsubject on 表名
for/after/instead of insert
as
if exists(select 1 from inserted) and not exists(select 1 from deleted)
begin
  update accountingsubjects set isend=0 where id in(select parentid from inserted)
end
go

更正如上
