为什么我的查询失败并显示 SQLCODE = -420？

Question

我能得到一些帮助吗？我将复制代码和错误。我查了错误代码

(DB2 SQL Error: SQLCODE=-420, SQLSTATE=22018, SQLERRMC=BOOLEAN)

但是我不明白什么不符合功能要求？我只是想把这些表拉出来，满足一定条件的时候重命名ACH_ORIGINATION.DESCRIPTION，然后过滤掉不符合要求的。我也想按 DESCRIPTION 分组，但我想先让这部分工作。

SELECT
    ACH_ORIGINATION.COMPANY_SERIAL,
    ACH_ORIGINATION.NAME,
    ACH_ORIGINATION.AMOUNT,
    ACH_ORIGINATION.NEXT_POSTING_DATE,
    CASE ACH_ORIGINATION.DESCRIPTION
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%J & J%' THEN 'J & J Electric'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%DeCleene%' THEN 'DeCleene'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%Arab%' THEN 'Arab'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%Clifford%' THEN 'Clifford Signs'
        ELSE 'Nothing'
    END AS DESCRIPTION
FROM
    CORE.ACH_ORIGINATION AS ACH_ORIGINATION
WHERE
    ACH_ORIGINATION.NEXT_POSTING_DATE IS NOT NULL AND
    DESCRIPTION <> 'Nothing'

错误：

Answer 1

根据评论，像这样修正 CASE 表达式：

CASE    WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%J & J%' THEN 'J & J Electric'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%DeCleene%' THEN 'DeCleene'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%Arab%' THEN 'Arab'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%Clifford%' THEN 'Clifford Signs'
        ELSE 'Nothing'
END AS DESCRIPTION

其实还是post一个新问题比较好，如果你原来的问题已经解决了，现在又有新问题了...
GROUP BY 的多个问题。您可以运行下面的查询来玩弄表达式。

1) 您必须在 GROUP BY 列表中未出现但在 SELECT 列表中使用的列上使用某些聚合函数。如果您取消注释掉的第一行，并注释掉下一行（使用 MAX 函数），您将得到 SQLCODE=-119。

2) GROUP BY 子句中的意外/错误表达式。
您应该在 group by 子句中使用相同的 case 表达式，而不是原始的 DESCRIPTION 列。如果您取消注释 --DESCRIPTION 行并注释掉 GROUP BY 列表中的 CASE 表达式，您可能 "suddenly" 意识到，您在DESCRIPTION 列。这是因为您首先按 DESCRIPTION 中的原始值分组，然后在 CASE 表达式中处理分组值。

SELECT
    --ACH_ORIGINATION.NEXT_POSTING_DATE,
    MAX(ACH_ORIGINATION.NEXT_POSTING_DATE) AS NEXT_POSTING_DATE,
    CASE 
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%J & J%' THEN 'J & J Electric'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%DeCleene%' THEN 'DeCleene'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%Arab%' THEN 'Arab'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%Clifford%' THEN 'Clifford Signs'
        ELSE 'Nothing'
    END AS DESCRIPTION
, COUNT(1) CNT    
FROM 
(
VALUES 
  (CURRENT DATE - 1, 'Arab1') 
, (CURRENT DATE - 2, 'Arab2')  
) ACH_ORIGINATION (NEXT_POSTING_DATE, DESCRIPTION)
WHERE
    ACH_ORIGINATION.NEXT_POSTING_DATE IS NOT NULL AND
    DESCRIPTION <> 'Nothing'
GROUP BY 
--DESCRIPTION
    CASE 
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%J & J%' THEN 'J & J Electric'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%DeCleene%' THEN 'DeCleene'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%Arab%' THEN 'Arab'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%Clifford%' THEN 'Clifford Signs'
        ELSE 'Nothing'
    END
;
