求一存储过程，一条记录变为多条记录
表A
name startno endno
aaaa 120 125
bbbb 110 160
插入表B中为
name no
aaaa 120
aaaa 121
... ...
aaaa 125
bbbb 110
bbbb 111
... ...
bbbb 160



[解决办法]
declare tb cursor for select name,startno,endno from from tablea
declare @i int
declare @a1 int
declare @a2 int
declare @name varchar(20)

open tb
fetch next from tb into @name,@a1,@a2
while @@fetch_status=0
begin
set @i = @a1
while (@i <= @a2)
begin
INSERT tableb (name,no) VALUES(@name,@i)
s et @i = @i + 1
end

fetch next from tb into @name,@a1,@a2
end
close tb
deallocate tb

--如果是100-2000就插不完
--------------------------------那就多产生行数，那就用交叉
Select id=identity(int,0,1) into #t from syscolumns as a,syscolumns as b
