您好，

以上查询包括：

  1. WITH CLAUSE - 此条款的目的是识别2011年至2016年期间购买商品的客户的不同"IDNUM"。
  2. 第一次查询 - 查询的主要目的是检查上述WITH CLAUSE中是否存在任何选定的"IDNUM"。此外，此查询应检查选定的"IDNUM"是否与特定"BUSS_ID"匹配，并在名为'MID'的列中将其标记为"DRIVE_TYPE"。
  3. 第二次查询 - 此查询与第一次查询几乎完全相同。唯一的区别是它在名为"IDNUM"的列中将'PRO'标记为"DRIVE_TYPE"。

    4. 您可能已经注意到，在两个查询中都有一个共同的"BUSS_ID": 'ABC'

    • 第一次查询 - , (CASE WHEN T1."BUSS_ID" IN ('ABC', 'DEF') THEN 'MID' ELSE NULL END) "DRIVE_TYPE"
    • 第二次查询 - , (CASE WHEN T1."BUSS_ID" IN ('ABC', 'JKL', 'PQR') THEN 'PRO'ELSE NULL END) "DRIVE_TYPE"

    我尝试过UNION这些查询来显示每一行，它们都是“BUSS_ID”，作为两行单独的结果。换句话说，如果一行有"BUSS_ID" of 'ABC'，那么select语句会显示两次。一行"DRIVE_TYPE"标记为'MID'，另一行标记为'PRO'。

    问题是，当我运行查询时，我收到以下错误：

      

    ORA-00604：递归SQL级别1发生错误

         

    ORA-00904：“来自$ _subquery $ _003”。“DATEKEY_0_0”：无效的标识符

    对我来说更令人困惑的是，我可以运行 WHERE CLAUSE + 1st Query 或 WITH CLAUSE + 2nd Query 的组合没有任何问题。 但是当我尝试运行 WITH CLAUSE + 1st Query + UNION + 2nd Query 时，我收到错误。

答案 0 :(得分：0)

这是关于CTE的伟大之处。试着用3个CTE重写一下，我敢打赌，如果你还有一个

，错误信息会更好

SELECT * FROM Q1
UNION
SELECT * FROM Q2

另外考虑将第一个CTE更改为使用与IDNUM不同的名称，可能是BOOKING_IDNUM 

WITH SubQry AS
(SELECT DISTINCT
TBL1.BOOKING_IDNUM
-- etc
