MySQL派生表问题

我希望能够从以下查询中输出以下字段：

AddedById,AddedByName,HoursWorked,CurrentYearlyFlexiAvailable

然而，当我的where addedby=1时，我想用字段名AddedById替换它，因为我不想硬编码这个值，因为整个查询应该并将返回多个人，我想从rpt_timesheet_数据视图中获取这个值，它就在那里。CurrentYearlyFlexiAvailable字段应该告诉我，通过在SELECT SUMttl和from SELECT SUMworked-420 as ttl之间进行计算，他们在当前年份至今还剩多少时间

但我一直得到：

错误代码：1054。“where子句”中的未知列“AddedById”

就在那个地方。我尝试了各种查询来对其进行排序，但就是想不出来。对不起，我不擅长解释这一点，我可以在脑海中看到我想做什么

下面是一个查询，其功能非常类似，它返回单个用户的结果，其中，如上所述的查询旨在循环所有用户并给出结果：-

    SELECT addedbyname, SUM(ttl) - 
    (SELECT SUM(worked) 
        FROM vwtimesheet 
        WHERE addedby=1 
        AND entrydate BETWEEN '2017-01-01' AND '2017-04-13' 
        AND activityid=3192 
        GROUP BY addedby ) AS CurrentYearlyFlexiAvailable 
    ,(SELECT SUM(worked) FROM vwtimesheet 
        WHERE addedby=1 
        AND entrydate BETWEEN '2017-01-01' AND '2017-04-13' 
        AND activityid=3192 
        GROUP BY addedby ) AS flexiused 
    ,(SELECT sum(worked) FROM vwtimesheet 
        WHERE addedby=1 
        AND entrydate BETWEEN DATE_FORMAT(NOW() ,'%Y-%m-01') AND curdate() 
        AND activityid=3192
        GROUP BY addedby ) as fleximonthused 
FROM ( SELECT entrydate,addedbyname,SUM(worked)-420 AS ttl FROM vwtimesheet 
    WHERE addedby=1 
    AND entrydate BETWEEN '2017-01-01' AND '2017-04-13' 
    AND projectid<>113 
    AND activityid<>3192 
    GROUP BY entrydate,addedbyname
    HAVING SUM(worked)>420 
) AS s

请尝试以下方法

SELECT AddedById,
       AddedByName,
       SUM( HoursWorked ) AS HoursWorked,
       SUM( ttl ) - sumWorked AS CurrentYearlyFlexiAvailable
FROM ( SELECT AddedById AS AddedById,
              AddedByName AS AddedByName
       FROM rpt_timesheet_data
       GROUP BY AddedById
     ) AS AddedByFinder
JOIN ( SELECT addedby AS addedby,
              entrydate AS entrydate,
              SUM( worked ) - 420 AS ttl
       FROM vwtimesheet
       WHERE entrydate BETWEEN '2017-01-01' AND '2017-04-13'
         AND projectid <> 113
         AND activityid <> 3192
       GROUP BY addedby,
                entrydate
       HAVING SUM( worked ) > 420
     ) AS ttlFinder ON AddedByFinder.AddedById = ttlFinder.addedby
JOIN ( SELECT addedby AS addedby,
              SUM( worked ) AS sumWorked
       FROM vwtimesheet
       WHERE entrydate BETWEEN '2017-01-01' AND '2017-04-13'
         AND activityid = 3192
       GROUP BY addedby
     ) sumWorkedFinder ON AddedByFinder.AddedById = sumWorkedFinder.addedby
WHERE entrydate BETWEEN '2017-04-02' AND '2017-04-13 23:59:59'
  AND ActivityId = 3192
GROUP BY AddedById,
         AddedByName 
ORDER BY AddedByName;

如果您有任何问题或意见，请随时发表相应的意见。

也许您应该问另一个问题。或者至少认真编辑一下这个。提供示例数据、所需结果，并描述您试图实现的逻辑。在内部查询中，您需要包括您要应用分组的字段。我将尝试更正您的代码，并在短时间内发布答案。您可能会发现阅读此内容很有帮助。您想做什么？哦，请稍候。我已更新了我的答案。请尽快回复我。谢谢@toonice，这正是我所需要的。我很快就会得到解释-我有点偏离了方向。可能很快就会和你交谈，出于某种原因，返回的ttl值实际上翻了一番，这使得ttl-sumWorked作为CurrentYearlyFlexibleAvailable计算的总和被抛出。如果我只是在自己的连接上运行第一个连接查询，那么我得到的值列表都是正确的，但是当ttl在连接之外使用时似乎是正确的

SELECT AddedById,
       AddedByName,
       SUM( HoursWorked ) AS HoursWorked,
       SUM( ttl ) - sumWorked AS CurrentYearlyFlexiAvailable
FROM ( SELECT AddedById AS AddedById,
              AddedByName AS AddedByName
       FROM rpt_timesheet_data
       GROUP BY AddedById
     ) AS AddedByFinder
JOIN ( SELECT addedby AS addedby,
              entrydate AS entrydate,
              SUM( worked ) - 420 AS ttl
       FROM vwtimesheet
       WHERE entrydate BETWEEN '2017-01-01' AND '2017-04-13'
         AND projectid <> 113
         AND activityid <> 3192
       GROUP BY addedby,
                entrydate
       HAVING SUM( worked ) > 420
     ) AS ttlFinder ON AddedByFinder.AddedById = ttlFinder.addedby
JOIN ( SELECT addedby AS addedby,
              SUM( worked ) AS sumWorked
       FROM vwtimesheet
       WHERE entrydate BETWEEN '2017-01-01' AND '2017-04-13'
         AND activityid = 3192
       GROUP BY addedby
     ) sumWorkedFinder ON AddedByFinder.AddedById = sumWorkedFinder.addedby
WHERE entrydate BETWEEN '2017-04-02' AND '2017-04-13 23:59:59'
  AND ActivityId = 3192
GROUP BY AddedById,
         AddedByName 
ORDER BY AddedByName;
