SELECT top n for multiple tables

這是一個「Select top n for group」的問題，除了我有4個表格並且需要幾個字段的MAX。SELECT top n for multiple tables

SELECT DISTINCT r.Id, p.Description AS Pathway, CONVERT(Varchar(10), s.CreateDate, 101) 
    AS [Date], s.OptionId, o.Description AS Options, s.Score, o.Risk 
FROM ucare.Responses r 
INNER JOIN ucare.RiskScores s ON s.ScheduleId = r.ScheduleId 
INNER JOIN ucare.PathwayOptions o ON o.Id = s.OptionId 
INNER JOIN ucare.Pathways p ON p.Id = r.PathwayId 
WHERE r.PathwayId IN 
    (SELECT DISTINCT PathwayId 
    FROM ucare.Responses 
    WHERE r.ScheduleId = '541') 
    AND Score IN 
    (SELECT DISTINCT MAX(Score) OVER (PARTITION BY s.OptionId) 
    FROM ucare.RiskScores WHERE ScheduleId = '541') 
    AND o.Risk IN 
    (SELECT DISTINCT MAX(Risk) OVER (PARTITION BY o.Id) AS Risk 
    FROM ucare.PathwayOptions) 
GROUP BY r.Id, s.OptionId, p.Description, s.Score, s.CreateDate, o.Description, o.Risk

的結果：

**Id Pathway   Date  OptionId Options   Score Risk** 
    1 Test pathway 1 6/19/2017 4  Test Option 1  160 10 
    10 Test pathway 2 6/19/2017 4  Test Option 1  160 10 
    17 Test pathway 3 6/19/2017 4  Test Option 1  160 10

我需要的是：

**Id Pathway   Date  OptionId Options   Score Risk** 
    1 Test pathway 1 6/19/2017 4  Test Option 1  160  10 
    10 Test pathway 2 6/19/2017 34  Test Option 2  62  10 
    17 Test pathway 3 6/19/2017 49  Test Option 3  50  2

凡OptionId，選項（o.Description），分數和風險更改ID更改時。任何幫助將不勝感激，謝謝，

至於敘述這概括了我要找的。首先，我們獲取與特定ScheduleId相關的所有響應（ucare.Responses），在這種情況下爲541.這將爲我們提供1,10和17的DISTINCT PathwayId，它們與ucare的查找錶鏈接。Pathways Description 。

從這裏541的ScheduleId鏈接ucare.RiskScores，它給了我們PathwayOptionsId's，CreateDate's和Scores。 PathwayOptionId用於鏈接到ucare.PathwayOptions表中的Id字段，我們可以在其中獲得匹配的PathwayOption說明，最近的（MAX（CreateDate））和匹配的MAX（風險）。

MAX風險用於打破RiskScore存在的任何關係。例如，如果我們查詢具有541的ScheduleId的ucare.RiskScores，則有4個匹配的PathwayOptionId's，1,2,4和5，其得分爲160，但具有8,7,10和9的風險。選項＃4具有MAX分數爲160，最大風險爲10，所以這是我們的選擇。這將完成ScheduleId 541的鏈接鏈。

這是新的CREATE/INSERT腳本，它具有所有要匹配的字段和適當的數據。

簡短的回答「CROSS APPLY SELECT TOP N FROM ... ORDER BY ...）如果你想要一個更好的答案，請提供測試數據在礦井創建表和插入數據腳本的形式。 –

我在查詢中沒有看到TOP n，並且我不知道什麼是「Top n for group」問題。請您提供解釋嗎？ – DVT

看看這是你要找的是什麼...（也改變了表，#TempTables爲別人誰願意沿着無需添加新的模式和真實的表到自己的測試環境中玩）

編輯：基於OP的新數據添加了新的解決方案。

17   Test pathway for updated count scoring algorithm 2017-06-19 49   Low risk range          50   0

一切似乎都跟得上你預期的輸出除了PathwayId 17具有2風險......我仔細檢查了數據...唯一的[數據庫中的Pathway 17/Risk 2]組合是針對[ScheduleId 2/Option 51]的，它只有16分。希望這會有所幫助。
