我想成为这个。请帮忙。什么是获取此数据的最佳查询。

ID  Badge   IN              OUT
--------------------------------------------
1   1507010 5/31/2018 8:51  5/31/2018 13:43
2   1708004 5/31/2018 6:35  5/31/2018 13:43
3   1708005 5/31/2018 19:23 6/1/2018 8:34
4   1708006 5/31/2018 7:51  6/1/2018 18:34
5   1708007 5/31/2018 19:23 6/1/2018 6:36
6   1708009 5/31/2018 7:12  5/31/2018 22:03

Answer 1

以下查询应该接近您想要的内容：

SELECT
    ID,
    Badge,
    MIN(CHECKTIME) AS [IN],
    MAX(CHECKTIME) AS [OUT]
FROM yourTable
GROUP BY
    ID,
    Badge;

我对徽章1708009的预期输出有疑问，因为该徽章的最早检查时间是7:11，而不是7:12。

Answer 2

我会在row_number()：

中使用subquery

select id, badge, min(checktime) as in, max(checktime) as out
from (select *,  row_number() over (partition by id, badge, cast(checktime as date), datepart(hh,checktime) 
                                       order by datepart(mm,checktime) desc) seq
      from table 
     ) t
where seq = 1
group by id, badge;

使用MS Access或SQL Server的出勤日志
