MySQL的派生表版本

Question

我想能夠輸出從下面的查詢中的以下字段：

AddedById,AddedByName,HoursWorked,CurrentYearlyFlexiAvailable 

然而，當我有WHERE addedby = 1，我想和替換此字段名稱AddedById因爲我不想硬編碼此值作爲整體查詢應該會返回多個人，我想從rpt_timesheet_data視圖得到這個值，這是在那裏。該CurrentYearlyFlexiAvailable場應該告訴我，他們有多少時間留給本年度迄今爲止通過執行SELECT SUM（TTL）的計算從FROM（SELECT SUM（工作）-420爲TTL

SELECT AddedById,AddedByName,SUM(HoursWorked) AS HoursWorked 
,(SELECT SUM(ttl) - (
       SELECT SUM(worked) 
       FROM vwtimesheet 
       WHERE addedby=AddedById 
       AND entrydate BETWEEN '2017-01-01' AND '2017-04-13' 
       AND activityid=3192 
       GROUP BY addedby) AS flexihours 

     FROM (
      SELECT SUM(worked)-420 AS ttl 
      FROM vwtimesheet 
      WHERE addedby=1 <!--HERE IS THE ISSUE 
      AND entrydate BETWEEN '2017-01-01' AND '2017-04-13' 
      AND projectid<>113 AND activityid<>3192 
      GROUP BY entrydate 
      HAVING SUM(worked)>420 
     ) AS s) AS CurrentYearlyFlexiAvailable 
FROM rpt_timesheet_data 
WHERE entrydate BETWEEN '2017-04-02' AND '2017-04-13 23:59:59' 
AND ActivityId=3192 
GROUP BY AddedById,AddedByName 
ORDER BY AddedByName 

，但我不斷收到：

錯誤代碼：1054在未知列'AddedById 'where子句'

剛在那一個地方。我已經嘗試過各種查詢來排序，但只是無法弄清楚。對不起不擅長解釋這一點，可以看到它在我的腦袋我想做...

這裏是做在它返回的結果爲單個用戶，非常類似的查詢，其中的一個以上是通過所有的用戶意味着環和給我的結果： -

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

請嘗試以下...

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;
