SELECT top n for multiple tables

这是一个“Select top n for group”的问题，除了我有4个表格并且需要几个字段的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

的结果：

**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，选项（o.Description），分数和风险更改ID更改时。任何帮助将不胜感激，谢谢，

至于叙述这概括了我要找的。首先，我们获取与特定ScheduleId相关的所有响应（ucare.Responses），在这种情况下为541.这将为我们提供1,10和17的DISTINCT PathwayId，它们与ucare的查找表链接。Pathways Description 。

从这里541的ScheduleId链接ucare.RiskScores，它给了我们PathwayOptionsId's，CreateDate's和Scores。 PathwayOptionId用于链接到ucare.PathwayOptions表中的Id字段，我们可以在其中获得匹配的PathwayOption说明，最近的（MAX（CreateDate））和匹配的MAX（风险）。

MAX风险用于打破RiskScore存在的任何关系。例如，如果我们查询具有541的ScheduleId的ucare.RiskScores，则有4个匹配的PathwayOptionId's，1,2,4和5，其得分为160，但具有8,7,10和9的风险。选项＃4具有MAX分数为160，最大风险为10，所以这是我们的选择。这将完成ScheduleId 541的链接链。

这是新的CREATE/INSERT脚本，它具有所有要匹配的字段和适当的数据。

简短的回答“CROSS APPLY SELECT TOP N FROM ... ORDER BY ...）如果你想要一个更好的答案，请提供测试数据在矿井创建表和插入数据脚本的形式。 –

我在查询中没有看到TOP n，并且我不知道什么是“Top n for group”问题。请您提供解释吗？ – DVT

看看这是你要找的是什么...（也改变了表，#TempTables为别人谁愿意沿着无需添加新的模式和真实的表到自己的测试环境中玩）

编辑：基于OP的新数据添加了新的解决方案。

结果...

1   COPD GOLD Classification       2017-06-19 4   GOLD Risk Level D - High Risk, High Symptom  160   10

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预期的输出除了PathwayId 17具有2风险......我仔细检查了数据...唯一的[数据库中的Pathway 17/Risk 2]组合是针对[ScheduleId 2/Option 51]的，它只有16分。希望这会有所帮助。
