指纹考勤记录怎么转换成考勤表呀！

[ztwz]

指纹库中有两张表一张是用户表字段如下
code name
2001 张三
2002 李四
2003 王五
.....
一张是指纹打卡记录表字段如下
编号 打卡时间
2001 2013/7/15 7:42
2001 2013/7/15 18:00
2002 2013/7/16 7:45
2002 2013/7/16 18:03
2003 2013/7/17 7:32
2001 2013/7/22 7:49
2003 2013/7/22 18:07
.....

现在我想把两张表转换成考勤表如下

请问我要这sql要怎么写？sql弱到爆想了一下午硬没搞出来。

这样吗：

--drop table t
--drop table tb
--go

create table t(code int, name varchar(20))

insert into t
select 2001,   '张三'
union all select 2002  , '李四'
union all select 2003  , '王五'
 
create table tb(编号 int,打卡时间 datetime)

insert into tb
select 2001   ,'2013/7/15 7:42'	
union all select 2001,   '2013/7/15 18:00'	
union all select 2002,   '2013/7/16 7:45'	
union all select 2002,   '2013/7/16 18:03'	
union all select 2003,   '2013/7/17 7:32'	
union all select 2001,   '2013/7/22 7:49'	
union all select 2003,   '2013/7/22 18:07'
go

要用存储过程来实现了

设计问题，非SQL查询问题

这个表可以从新设计，在导入数据的时候添加到更合理的表中。

我的想法添加一张临时表，然后动态行专列 create table #t(code int, name varchar(20)) insert into #t select 2001, '张三' union all select 2002 , '李四' union all select 2003 , '王五' create table #tb(code int,checktime datetime) insert into #tb select 2001 ,'2013/7/15 7:42' union all select 2001, '2013/7/15 18:00' union all select 2002, '2013/7/16 7:45' union all select 2002, '2013/7/16 18:03' union all select 2003, '2013/7/17 7:32' union all select 2001, '2013/7/22 7:49' union all select 2003, '2013/7/22 18:07' select name,case when CONVERT(varchar,checktime,108)>'12:00' THEN '下午' else '上午' end as [day], CONVERT(varchar,checktime,108)as tim,CONVERT(varchar,checktime,111)as dat into #test from #tb a,#t b where a.code=b.code declare @s varchar(max) select @s=ISNULL(@s+',','')+'['+dat+']' from #test group by dat order by dat set @s='select * from #test pivot (max(tim) for dat in ('+@s+'))A order by name,day' exec (@s)

这个就是行列转换问题。百度一下，帖子一大把。另外考勤这个东西，如果某天都没打卡，那么这个时间就不会出现在打卡记录表里面，所以写语句之前，考虑怎么把需要统计的时间范围之类的所有时间都给生成，防止缺少某天的日期
