いくつかのレコードを名前でグループ化し、いくつかの値をピボットする方法

Question

IDによるビューの結果をグループ化するためにSQLクエリを作成しています。 最大ピボット結果が3つあり、 ：TestCaseId、TestName、Test Case Num、Owner

実際にはこれはクエリiがDesired出力を得るために作成したものですが、MAXは常に最大値を取得しているため期待通りに動作していますが、ピボットされた値が右側に繰り返されます。

 
SELECT DISTINCT TBL1.[TestName], TBL1.[Test Case Num], TBL1.[Owner], MAX(TBL1.[Browser]) as 'Column1', MAX(TBL1.[Run Date]) as 'Column2', MAX(TBL1.[Status]) as 'Column3', MAX(TBL1.[Duration]) as 'Column4', MAX(TBL1.[ErrorMsg]) as 'Column5', MAX(TBL2.[Browser]) as 'Column6', MAX(TBL2.[Run Date]) as 'Column7', MAX(TBL2.[Status]) as 'Column8', MAX(TBL2.[Duration]) as 'Column9', MAX(TBL2.[ErrorMsg]) as 'Column10', MAX(TBL3.[Browser]) as 'Column11' , MAX(TBL3.[Run Date]) as 'Column12', MAX(TBL3.[Status]) as 'Column13', MAX(TBL3.[Duration]) as 'Column14', MAX(TBL3.[ErrorMsg]) as 'Column15' 
FROM (SELECT DISTINCT T1.[TestCaseId], T1.[TestName], T1.[Test Case Num], T1.[Owner], T1.[Browser], T1.[Run Date], T1.[Status], T1.[Duration], T1.[ErrorMsg] 
FROM [TestRunner].[dbo].RunsRawResults T1) TBL1 
cross apply (SELECT DISTINCT T2.[TestCaseId], T2.[Browser], T2.[Run Date], T2.[Status], T2.[Duration], T2.[ErrorMsg] 
      FROM [TestRunner].[dbo].RunsRawResults T2 
      WHERE T2.[TestCaseId] = TBL1.[TestCaseId] AND T2.[Run Date] TBL1.[Run Date]) TBL2 
cross apply (SELECT DISTINCT T3.[TestCaseId], T3.[Browser], T3.[Run Date], T3.[Status], T3.[Duration], T3.[ErrorMsg] 
      FROM [TestRunner].[dbo].RunsRawResults T3 
      WHERE T3.[TestCaseId] = TBL2.[TestCaseId] AND T3.[Run Date] TBL2.[Run Date] AND T3.[Run Date] TBL1.[Run Date]) TBL3 
      GROUP BY TBL1.[TestCaseId], TBL1.[TestName], TBL1.[Test Case Num], TBL1.[Owner] 

入力 - 生データ（RunRawResultsビューから来る） 希望と旋回し出力我々は、複数の実行の識別および順序を簡素化することができcommon table expression (cte)とrow_number()を使用して

Answer 1

日付。これにより、distinctとgroup byを使用してスキップすることもできます。

outer applyに切り替えると、TestCaseIdに3回未満の実行結果が含まれます。

;with cte as (
    select * 
    , rn = row_number() over (
     partition by TestCaseId 
     order by [Run Date]
