游标的问题，麻烦高手看下

Alter proc pro_getName
as
declare @name varchar(200)
declare mycursor cursor Scroll for select mtvnam from mtv v where v.mtvtyp='来源'
open mycursor
fetch next from mycursor into @name;
while(@@FETCH_STATUS=0)
begin
print @name
end
close mycursor
deallocate mycursor

exec pro_getName 发现是个死循环，查询只是9条数据，为什么那？
还有就是sql中循环有几种写法？麻烦举个例子，谢谢
