schwenken zu erstellen Versuch und Datumswerte

Question

Der Versuch, zurückzukehren eine Pivot-Tabelle in SQL zu erstellen Datumswerten zurückzukehren, noch nie gemacht, aber ich habe in eine Wand und nur return ‚Null‘ Werte laufen. Ist es möglich, Datumswerte zurückzugeben? Schätze jede Hilfe! Abfrage unter:

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 

Dies ist die aktuelle Tabelle: enter image description here

aber ich will es so aussehen: enter image description here

Try this -

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
