if object_id('[TB]') is not null drop table [TB]
go
create table [TB] (col1 nvarchar(2),col2 nvarchar(2),col3 int)
insert into [TB]
select 'a','b',4 union all
select 'c','d',1 union all
select 'e','f',2
select * from [TB]
SELECT col1,col2
FROM dbo.TB
INNER JOIN master..spt_values M ON TB.col3>M.number AND M.type = 'P'
/*
col1 col2
a b
a b
a b
a b
c d
e f
e f*/------解决方案--------------------
select col1,col2 from tb,master.spt_values where type='p' and number between 1 and col3
