我正在尝试从我的mysql数据库获取员工的每周工作报告。
我有四张桌子：
stdjobs (ID, NR, Name, Gruppe)
user (ID, vname, nname, NR)
wtime (ID, usr, job, tin, tout)
Groups (idGroups, NR, Name)
在stdjobs中是一些标准作业代码的全名。在user我有一些关于我的用户的更多详细信息。此查询不使用Groups。
wtime是主表，员工进入工作时间（通过简单的c-prog和条形码扫描仪）。
select * from wtime order by id desc limit 5;
返回类似这样的内容：
ID usr job tin tout
4843 M0005 A001942 2015-11-10 15:18:47 NULL
4842 M0006 A001843 2015-11-10 14:47:23 NULL
4841 M0007 A001814 2015-11-10 13:33:37 NULL
4840 M0007 .000002 2015-11-10 13:27:10 2015-11-10 13:33:37
4839 M0006 A001814 2015-11-10 13:25:19 2015-11-10 14:47:23
tout - 带有NULL的字段表示实际工作的作业。
我希望每个员工每周都能获得一份报告，其中包括白天和整个星期的总和。看起来应该是这样的：
Report for Gxxxxxxx Zxxxxxxxxxx
Date Job In Out Time
Mon, 15.01.2015 A001814 06:58:35 08:45:26 01:46:51
Mon, 15.01.2015 A001925 08:45:26 09:45:26 01:00:00
Mon, 15.01.2015 NULL NULL NULL 02:46:51
Thu, 16.01.2015 A001814 06:00:00 08:00:00 02:00:00
Thu, 16.01.2015 A001925 08:00:00 10:00:00 02:00:00
Thu, 16.01.2015 NULL NULL NULL 04:00:00
NULL NULL NULL NULL 06:46:51
现在我有以下查询：
SET lc_time_names = 'de_AT';
SELECT
(SELECT
CONCAT(vname, ' ', nname)
FROM
zeiterf.user
WHERE
nr = zeiterf.wtime.usr
LIMIT 1) AS 'Name',
DATE_FORMAT(tin, '%a %e.%c.%Y') AS 'Datum',
IF((SELECT
name
FROM
zeiterf.stdjobs
WHERE
nr = zeiterf.wtime.job
LIMIT 1) != '',
(SELECT
name
FROM
zeiterf.stdjobs
WHERE
nr = zeiterf.wtime.job
LIMIT 1),
job) AS 'Auftrag',
TIME(tin) AS 'Ein',
IF(job != '...ENDE', TIME(tout), NULL) AS 'Aus',
(IF(job != '...ENDE',
SEC_TO_TIME(UNIX_TIMESTAMP(tout) - UNIX_TIMESTAMP(tin)),
NULL)) AS 'Zeit'
FROM
zeiterf.wtime
WHERE
usr = 'M0006' AND job != '...ENDE'
AND DATE(tin) > (DATE_SUB(CURDATE(), INTERVAL 1 WEEK))
GROUP BY usr , DATE(tin) , id;
它可以很好地为我提供所需的所有行。但我不知道如何每天和每周插入总和。
当前输出：

任何人都可以给我一个提示吗？
答案 0 :(得分：1)
SQLFiddle目前无效，但我会尝试向您解释如何实现目标。
首先，您需要通过WEEKOFYEAR（）函数知道每个tint日期的周。此值可帮助您分别对每周求和。然后，您可以进行如下查询：
select WEEKOFYEAR(tin) as numWeek,
DATE(tin) as dateJob,
DAYOFWEEK(tin) dayOfWeek,
usr,
job,
(IF( ISNULL(tout), UNIX_TIMESTAMP(), UNIX_TIMESTAMP(tout) ) - UNIX_TIMESTAMP(tin)) as DiffInOut
from wtime;
现在，您可以使用每个字段（numWeek，usr，dayOfWeek，dateJob和job）对数据进行分组，以获取详细查询：
select numWeek,
usr,
dayOfWeek,
datejob,
job,
sum(DiffInOut)
from
(
select WEEKOFYEAR(tin) as numWeek,
DATE(tin) as dateJob,
DAYOFWEEK(tin) dayOfWeek,
usr,
job,
(IF( ISNULL(tout), UNIX_TIMESTAMP(), UNIX_TIMESTAMP(tout) ) - UNIX_TIMESTAMP(tin)) as DiffInOut
from wtime
) result
group by numWeek, usr, dayOfWeek, datejob, job
后来建立一个工会，每周只获取信息..
union
select numWeek,
usr,
dayOfWeek,
null,
null,
sum(DiffInOut)
from
(
select WEEKOFYEAR(tin) as numWeek,
NULL as dateJob,
8 dayOfWeek,
usr,
job,
(IF( ISNULL(tout), UNIX_TIMESTAMP(), UNIX_TIMESTAMP(tout) ) - UNIX_TIMESTAMP(tin)) as DiffInOut
from wtime
) result
group by numWeek, usr, dayOfWeek
order by numWeek, usr, dayOfWeek;
我希望SQL Fiddle适合你。
结果：
| numWeek | usr | dayOfWeek | datejob | job | sum(DiffInOut) |
|---------|-------|-----------|----------------------------|---------|----------------|
| 46 | M0005 | 3 | November, 10 2015 00:00:00 | A001942 | 61314 |
| 46 | M0005 | 8 | (null) | (null) | 61314 |
| 46 | M0006 | 3 | November, 10 2015 00:00:00 | A001843 | 61314 |
| 46 | M0006 | 3 | November, 10 2015 00:00:00 | A001814 | 0 |
| 46 | M0006 | 8 | (null) | (null) | 61314 |
| 46 | M0007 | 3 | November, 10 2015 00:00:00 | A001814 | 61314 |
| 46 | M0007 | 3 | November, 10 2015 00:00:00 | .000002 | 0 |
| 46 | M0007 | 8 | (null) | (null) | 61314 |
PD：字段8 dayOfWeek是正确订购周行的一个小技巧。
PD2：我的SQL小提琴示例查询会抛出此结果：
| numWeek | usr | dayOfWeek | datejob | job | sum(DiffInOut) |
