添加包含父級的cte的列

Question

我在View中具有以下代碼，可以很好地工作並提供所需的輸出。

;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 

我需要添加一個多個列，使該輸出MJob（不是SORCE數據MJob）爲每個記錄的父。

源數據的格式如下：

╔═════════════════════════╗ 
║ SJob,MJob,GroupF  ║ 
╠═════════════════════════╣ 
║ 10001000,NULL,True  ║ 
║ 10001001,NULL,True  ║ 
║ 10001002,NULL,True  ║ 
║ 20001000,10001000,True ║ 
║ 20001001,10001001,True ║ 
║ 20001002,10001001,True ║ 
║ 20001003,10001002,True ║ 
║ 30001000,20001000,False ║ 
║ 30001001,20001000,False ║ 
║ 30001002,20001001,False ║ 
║ 30001003,20001002,False ║ 
║ 30001004,20001002,False ║ 
║ 30001005,20001003,False ║ 
║ 30001006,20001003,False ║ 
║ 30001007,30001000,False ║ 
║ 30001008,30001000,False ║ 
║ 30001009,30001001,False ║ 
║ 30001010,30001002,False ║ 
║ 30001011,30001002,False ║ 
║ 30001012,30001003,False ║ 
║ 30001013,30001004,False ║ 
║ 30001014,30001005,False ║ 
║ 30001015,30001006,False ║ 
║ 30001016,30001006,False ║ 
╚═════════════════════════╝ 

我不知道如何解決它。
建議將不勝感激。

所需的輸出低於：

的問題是沒有完全清楚，我，但我知道你想是這樣的：

;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 

工作示例可以發現在SQL Fiddle。
請讓我知道，如果這不是你所問的，我會盡力給你一個更好的答案。
