不能编辑触发器！报如下错误！
[SQL-DMO]名称“deltype”在triggers集合中找不到！如果该名称是限定名，请使用[]分割名称的各部分，然后再试！

我的代码如下：
create   trigger   [delType]
on   [TypeTable]
for   delete
as
if   ((select   parentID   from   deleted   )> 0   )
update   TypeTable  
set   typeChildren   =   typeChildren   -   1,
        endTag   =   0
where   typeID   in   (select   parentID   from   deleted   )
GO

运行显示成功执行，在表下也能看到新建的触发器！
但就是要再编辑的时候总是报上面的错误！



------解决方案--------------------
try

if exists(select 1 from sysobjects where xtype= 'TR ' and name= 'delType ')
drop trigger delType
go
create trigger [delType]
on [CMS].dbo.[TypeTable]
for delete
as

if ((select parentID from deleted )> 0 )
update TypeTable
set typeChildren = typeChildren - 1,
endTag = 0
where typeID in (select parentID from deleted )


GO
