！触发器跳不过去？

求助！！！触发器跳不过去？？？
create trigger interg_disc　
on members
for update　
as
begin
  /*declare @memberID int,@integral int
  select @memberID=memberID ,@integral=integral from members where status='true'
  if(@integral>300 and @integral<600 )
  update members set discount=0.8 where [email protected]
  else if(@integral>600)
  update members set discount=0.7 where [email protected]
  update members set status='false' where [email protected]*/
end

跳出：消息 102，级别 15，状态 1，第 1 行
'　' 附近有语法错误。

------解决方案--------------------
interg_disc后又一个全角空格
------解决方案--------------------
这样就行了.

SQL code

create trigger interg_discon membersfor updateasbegindeclare @memberID int,@integral int  select @memberID=memberID ,@integral=integral from members where status='true'  if(@integral>300 and @integral<600 )  update members set discount=0.8 where [email protected]  else if(@integral>600)  update members set discount=0.7 where [email protected]  update members set status='false' where [email protected]end
------解决方案--------------------
begin和end之间要有内容
