加入和SUMS？

Question

嗨看看下面的表格： 隊，teamPoints，team_members，pointsTable 我試圖總結團隊成員分，然後求和隊分：

Teams 
|TeamID |TeamName | TeamLocation| 
------------------------------- 
|1  | sm1  | location1| 
|2  | sm2  | location2| 


TeamPoints 
|TeamID |TotalPonts | RemainderPonts| 
------------------------------- 
|1  | 10   | 7   | 
|1  | 8   | 6   | 
|2  | 8   | 6   | 


team_members 
|TeamID |UserID | 
----------------- 
|1  | 1  | 
|1  | 2  | 
|2  | 3  | 


pointsTable 
|UserID |TotalPonts | RemainderPonts| 
------------------------------- 
|1  | 10   | 7   | 
|2  | 8   | 6   | 
|2  | 8   | 6   | 


so results for team sm1 (TeamID =1) should be 

TeamName=sm1,TeamPoints.TotalPonts =18, TeamPoints.RemainderPonts=13 
pointsTable.TotalPonts =26, pointsTable.RemainderPonts=19 

這工作總結成員分，但有麻煩與球隊分

SELECT 
    teams.TeamID AS theTeamID, 
    teams.TeamName, 
    teams.TeamLocation, 
    team_members.TeamID, 
    team_members.UserID, 
    SUM(pointstable.RemainderPoints) AS points 
FROM 
    teams 
     LEFT JOIN 
    team_members ON teams.TeamID = team_members.TeamID 
     LEFT JOIN 
    pointstable ON team_members.UserID = pointstable.UserID 
GROUP BY teams.TeamID 

試圖

SELECT 
    teams.TeamID AS theTeamID, 
    teams.TeamName, 
    teams.TeamLocation, 
    team_members.TeamID, 
    team_members.UserID, 
    SUM(pointstable.RemainderPoints) AS points, 
    teampoints.TeamID AS tpID, 
    SUM(teampoints.TotalPoints) AS teamRedeamable 
FROM 
    teams 
     LEFT JOIN 
    team_members ON teams.TeamID = team_members.TeamID 
     LEFT JOIN 
    pointstable ON team_members.UserID = pointstable.UserID 
     LEFT JOIN 
    teampoints ON teams.TeamID = teampoints.TeamID 
GROUP BY teams.TeamID 

但似乎改變/乘以原始值 也嘗試過選擇，但需要一些如何組？

任何幫助，歡迎

認爲你需要一個子查詢來獲取用戶分表的細節，並加入該對主表： -

SELECT 
    teams.TeamID AS theTeamID, 
    teams.TeamName, 
    teams.TeamLocation, 
    SUM(pointstable.RemainderPoints) AS RemainderPonts, 
    SUM(pointstable.TotalPonts) AS TotalPonts, 
    Sub1.UserTotalPoints, 
    Sub1.UserRemainderPoints, 
    Sub2.TeamTotalPoints, 
    Sub2.TeamRemainderPoints 
FROM teams 
LEFT JOIN team_members ON teams.TeamID = team_members.TeamID 
LEFT JOIN pointstable ON team_members.UserID = pointstable.UserID 
LEFT OUTER JOIN 
(
    SELECT TeamID, SUM(TotalPoints) AS UserTotalPoints, SUM(RemainderPoints) AS UserRemainderPoints 
    FROM team_members 
    INNER JOIN pointsTable 
    ON team_members.UserID = pointsTable.UserID 
    GROUP BY TeamID 
) Sub1 
ON Sub1.TeamID = teams.TeamID 
LEFT OUTER JOIN 
(
    SELECT TeamID, SUM(TotalPoints) AS TeamTotalPoints, SUM(RemainderPoints) AS TeamRemainderPoints 
    FROM TeamPoints 
    GROUP BY TeamID 
) Sub2 
ON Sub0.theTeamID = Sub2.TeamID 
GROUP BY teams.TeamID, teams.TeamName, teams.TeamLocation 

注意，這是稍微躲閃它在SELECT中包含非聚合列，它們不在GROUP BY子句中。在這種情況下，默認的MySQL設置應該沒問題，但是如果使用不同的數據庫（或者取決於MySQL設置），您可能需要將其作爲2個不同的子查詢並將它們結合在一起。

SELECT Sub0.theTeamID, Sub0.TeamName, Sub0.TeamLocation, Sub0.RemainderPonts, Sub0.TotalPonts, Sub1.UserTotalPoints, Sub1.UserRemainderPoints, Sub2.TeamTotalPoints, Sub2.TeamRemainderPoints 
FROM 
(
    SELECT 
     teams.TeamID AS theTeamID, 
     teams.TeamName, 
     teams.TeamLocation, 
     SUM(pointstable.RemainderPoints) AS RemainderPonts, 
     SUM(pointstable.TotalPonts) AS TotalPonts 
    FROM teams 
    LEFT OUTER JOIN team_members ON teams.TeamID = team_members.TeamID 
    LEFT OUTER JOIN pointstable ON team_members.UserID = pointstable.UserID 
) Sub0 
LEFT OUTER JOIN 
(
    SELECT TeamID, SUM(TotalPoints) AS UserTotalPoints, SUM(RemainderPoints) AS UserRemainderPoints 
    FROM team_members 
    INNER JOIN pointsTable 
    ON team_members.UserID = pointsTable.UserID 
    GROUP BY TeamID 
) Sub1 
ON Sub0.theTeamID = Sub1.TeamID 
LEFT OUTER JOIN 
(
    SELECT TeamID, SUM(TotalPoints) AS TeamTotalPoints, SUM(RemainderPoints) AS TeamRemainderPoints 
    FROM TeamPoints 
    GROUP BY TeamID 
) Sub2 
ON Sub0.theTeamID = Sub2.TeamID
