的Sql透視和逆透視

Question

一個新手here..Actually我在甲骨文vw_summary一個表作爲

Onum | Uacheck | Uadesc | AU11 | AU12 | BD10 | 
---------------------------------------------------------- 
1 | 5.1 | VENDOR | 0 | 0 | 0 | 

2 | 5.2A | CUST | 0 | 0 | 0 | 

，我需要顯示的數據： -

Onum | PLant | 5.1 - VENDOR | 5.2A - CUST 
--------------------------------------------------- 

1  | AU11 | 0    | 0 

2  | AU12 | 0    | 0 

3  | BD10 | 0    | 0 

即我需要的列AU11, AU12, BD10到成爲我的工廠專欄 的行以及UACHECK || UADESC的每個級聯以成爲行。

試試這個：

WITH T1 AS (SELECT * 
      FROM vw_summary UNPIVOT (plantvalue 
          FOR plant 
          IN (AU11, AU12, BD10))), 
    T2 
     AS (SELECT UACHECK, 
        UADESC, 
        PLANT, 
        PLANTVALUE, 
        ROW_NUMBER() OVER (PARTITION BY UADESC ORDER BY UADESC) 
         AS NUM 
       FROM T1) 
SELECT * 
    FROM t2 PIVOT (MIN (PLANTVALUE) 
      FOR (UADESC, UACHECK) 
      IN (('VENDOR', '5.1') AS "5.1 - VENDOR", 
       ('CUST', '5.2A') AS "5.2A - CUST"));
