游标滚动，最后一条fetch两次？该怎么解决

游标滚动，最后一条fetch两次？
现在查询的结果集如下：
departid name
 1 alex
 1 david
 2 susan
 2 linda
想把结果集变成如下形式：
departid name
 1 alex,david
 2 susan,linda

自己使用方法如下：
declare @aa varchar(10),@bb varchar(50),@cc varchar(10),@dd varchar(10)
create table #temp1
(
  departid varchar(10),
  name varchar(50)
)
declare cur cursor for
select deartid, name from testcur order by deartid
open cur
fetch next from cur into @aa,@bb
while @@FETCH_STATUS=0
begin
   
  fetch next from cur into @cc,@dd

  if(@aa=@cc)
  begin
  select @bb = @bb+','+@dd
  end

  else
  begin
  insert into #temp1 values(@aa,@bb)
  set @aa = @cc
  set @bb = @dd
  end
  
end
  insert into #temp1 values(@aa,@bb)

close cur
deallocate cur

select * from #temp1  

显示情况如下：
departid name
 1 alex,david
 2 susan,linda,linda
为什么会多个linda呢？

至于解决方法见：http://topic.csdn.net/u/20120323/17/5669097e-1e45-4c20-aab1-bace2794bb25.html?1159773523

小弟再次发帖只是不明白自己错在哪里了，求指点！！
