多个触发器怎么设置

alter trigger oknumcgxd --第1次运行时，create,
on [dbo].[newmoo_case_cgxd]
for insert
as
begin
  declare @caseid bigint
  declare @ischeck int
  select @caseid = caseid from inserted
  select @ischeck = ischeck from inserted

  if exists(select id from newmoo_case where id=@caseid and ischeck >='5')
     begin     
       update a set a.oknum=b.productnum,end_date=getdate()
       from newmoo_case a,(select caseid,productnum=sum(productnum) from newmoo_case_cgxd where ischeck >='5' group by caseid ) b
       where ischeck >='5'and a.id=b.caseid
     end
  else
     begin
       insert into newmoo_case(id,oknum,end_date)
       select caseid,productnum,getdate() from inserted
     end


  if exists(select id from newmoo_case where id=@caseid and ischeck ='3')
     begin     
       update a set a.oknum=b.productnum,end_date=getdate()
       from newmoo_case a,(select caseid,productnum=sum(productnum) from newmoo_case_cgxd where ischeck ='3' group by caseid ) b
       where ischeck ='3'and a.id=b.caseid
     end
  else
     begin
       insert into newmoo_case(id,oknum,end_date)
       select caseid,productnum,getdate() from inserted
     end

 end

代码如上 我设置了两个触发器，如果单独写一个，触发器可以正常工作，
但是如果 像上面 把两个触发器写在一起，或者分别做成两个独立的触发器，
都会不工作，请问是什么原因。应该怎么解决，

非常感谢
