用sql脚本 为每一个单据，依次 跟正 行号
现有表如下
if exists(select *from sysobjects where name ='aa' and xtype='u') drop table aa
create table aa (日期 varchar(20),单据号 int,单据行号 int)
insert into aa
select '200801' , 22 ,'1' union all
select '200801' , 22 ,'1' union all
select '200801' , 23 ,'1' union all
select '200801' , 23 ,'1' union all
select '200801' , 23 ,'1' union all
select '200801' , 28 ,'1' union all
select '200801' , 28 ,'1' union all
select '200801' , 28 ,'1' union all
select '200801' , 28 ,'1' union all
select '200801' , 28 ,'1' union all
select '200801' , 28 ,'1' union all
select '200801' , 28 ,'1' union all
select '200801' , 28 ,'1' union all
select '200801' , 28 ,'1' union all
select '200801' , 29 ,'1' union all
select '200801' , 29 ,'1' union all
select '200801' , 30 ,'1' union all
select '200801' , 30 ,'1' union all
select '200801' , 30 ,'1' union all
select '200801' , 31 ,'1' union all
select '200801' , 31 ,'1' union all
select '200801' , 31 ,'1' union all
select '200801' , 31 ,'1'
select * from aa

--为每一个单据，依次 跟正 行号，
---用sql脚本 使其出现如下结果

select '200801' , 22 ,'1' union all
select '200801' , 22 ,'2' union all
select '200801' , 23 ,'1' union all
select '200801' , 23 ,'2' union all
select '200801' , 23 ,'3' union all

引用:
SQL code

if exists(select *from sysobjects where name ='aa' and xtype='u') drop table aa
create table aa (日期 varchar(20),单据号 int,单据行号 int)
insert into aa
select '200801' , 22 ,'1'……

不用，直接使用相关子查询就能实现。
