ピボットを作成して日付の値を返そうとしています

Question

日付の値を返すためにsqlでピボットテーブルを作成しようとしましたが、これは決して前に行われませんでしたが、壁に入って 'Null'日付の値を返すことは可能ですか？助けをよろしく！以下のクエリ： enter image description here

が、私はそれは次のようになりたい：：

SELECT SYS_ID, JOB_ID, 
[JOB_OPENED] AS A, [JOB_ENDED] AS B, [ROW_CONSTRUCTED] AS C, [SITE_CONSTRUCTED] AS D, [CONTRACT_ASBUILT_COMPLETE] AS E, [FIBER_ASBUILT_COMPLETE] AS F, [COAX_ASBUILT_COMPLETE] AS G, [JOB_RECONCILED] AS H 
FROM 
(SELECT COMPLETION_DATE, DATE_MILESTONE_NAME, SYS_ID, JOB_ID 

FROM EIMS.JOB_MILESTONES_RV) AS RV 
PIVOT 
(MAX(COMPLETION_DATE) 
FOR DATE_MILESTONE_NAME IN ([JOB_OPENED], [JOB_ENDED], [ROW_CONSTRUCTED], [SITE_CONSTRUCTED], [CONTRACT_ASBUILT_COMPLETE], [FIBER_ASBUILT_COMPLETE], [COAX_ASBUILT_COMPLETE], [JOB_RECONCILED]) 
) AS PivotTable 
WHERE JOB_ID > 40000 
AND SYS_ID = 8778 
ORDER BY JOB_ID 

これは、現在のテーブルであるenter image description here

これを試してみてください -

SELECT SYS_ID 
     ,JOB_ID 
     ,MAX(CASE WHEN DATE_MILESTONE_NAME = 'JOB OPENED' THEN COMPLETION_DATE END) AS "JOB OPENED" 
     ,MAX(CASE WHEN DATE_MILESTONE_NAME = 'JOB ENDED' THEN COMPLETION_DATE END) AS "JOB ENDED" 
     ,MAX(CASE WHEN DATE_MILESTONE_NAME = 'SITE CONSTRUCTED' THEN COMPLETION_DATE END) AS "SITE CONSTRUCTED" 
FROM YOUR_TABLE 
GROUP BY SYS_ID 
     ,JOB_ID
