Question

잘 작동하고 필요한 출력을 제공하는보기에 다음 코드가 있습니다.

;WITH ctesample 
    AS (SELECT sjob, 
       mjob, 
       mjob AS DisplayMJob, 
       groupf, 
       0 AS LVL 
     FROM dbo.vw_jobcosting_wipmastersub 
     WHERE (groupf = 'True') 
     UNION ALL 
     SELECT vw_JobCosting_WIPMasterSub_1.sjob, 
       vw_JobCosting_WIPMasterSub_1.mjob, 
       CASE S.lvl 
        WHEN 0 THEN S.sjob 
        ELSE S.displaymjob 
       END  AS DisplayMJob, 
       vw_JobCosting_WIPMasterSub_1.groupf, 
       S.lvl + 1 AS Expr1 
     FROM ctesample AS S 
       INNER JOIN dbo.vw_jobcosting_wipmastersub AS 
          vw_JobCosting_WIPMasterSub_1 
         ON S.sjob = vw_JobCosting_WIPMasterSub_1.mjob 
     WHERE (vw_JobCosting_WIPMasterSub_1.groupf = 'False')) 
SELECT sjob, 
     CASE 
     WHEN displaymjob IS NULL THEN sjob 
     ELSE displaymjob 
     END AS MJob, 
     groupf 
FROM ctesample AS cteSample_1 

I는 각 레코드에 대한 출력 MJob (안 SORCE 데이터 MJob)의 부모를주는 하나 개 이상의 항목을 추가 할 필요가있다.

소스 데이터 형식은 다음과 같습니다

나는 그것을 해결하는 방법을 모르겠어요.
제안 사항을 크게 높이세요.

이 문제는 나에게 완전히 명확하지 않았다,하지만 내가 이해에서 당신은 다음과 같이합니다 :

필요한 출력은 다음과 같습니다 동작하는 예제를 찾을 수

;WITH ctesample 
    AS (SELECT sjob, 
       mjob, 
       mjob AS DisplayMJob, 
       groupf, 
       0 AS LVL, 
       NULL outputMjob 
     FROM dbo.vw_jobcosting_wipmastersub 
     WHERE (groupf = 'True') 
     UNION ALL 
     SELECT vw_JobCosting_WIPMasterSub_1.sjob, 
       vw_JobCosting_WIPMasterSub_1.mjob, 
       CASE S.lvl 
        WHEN 0 THEN S.sjob 
        ELSE S.displaymjob 
       END  AS DisplayMJob, 
       vw_JobCosting_WIPMasterSub_1.groupf, 
       S.lvl + 1 AS Expr1, 
       S.mjob 
     FROM ctesample AS S 
       INNER JOIN dbo.vw_jobcosting_wipmastersub AS 
          vw_JobCosting_WIPMasterSub_1 
         ON S.sjob = vw_JobCosting_WIPMasterSub_1.mjob 
     WHERE (vw_JobCosting_WIPMasterSub_1.groupf = 'False')) 
SELECT sjob, 
     CASE 
     WHEN displaymjob IS NULL THEN sjob 
     ELSE displaymjob 
     END AS MJob, 
     groupf, 
     outputmjob 
FROM ctesample AS cteSample_1
