甲骨文求和

Question

我无法使“求和”正常工作。我不确定 select 语句中的 Sum 是否有效，因为我是 Oracle SQL 的新手。我正在尝试找出应付总额大于客户信用额度的地方。

SELECT ARCUSTO.CUSTNO,
       ARCUSTO.COMPANY,
       ARCUSTO.ID,
       ARCUSTO.FAX_NUMBER,
       ARCUSTO.STATUS_ID,
       ARCUSTO.CREDIT_LIMIT,
       ARCUSTO.ADDR1,
       ARCUSTO.ADDR2,
       ARCUSTO.ADDR3,
       ARCUSTO.CITY,
       ARCUSTO.STATE,
       ARCUSTO.ZIP,
       ARCUSTO.COUNTRY,
       ARCUSTO.PHONE_NUMBER,
       SUM(V_1_30_SUM.LEFT_TO_APPLY, V_30_60_SUM.LEFT_TO_APPLY, V_60_90_SUM.LEFT_TO_APPLY, V_90_SUM.LEFT_TO_APPLY, V_CURRENT_SUM.LEFT_TO_APPLY) Due
FROM   ( ( ( (IQMS.ARCUSTO ARCUSTO
              LEFT OUTER JOIN IQMS.V_1_30_SUM V_1_30_SUM
              ON ARCUSTO.ID=V_1_30_SUM.ARCUSTO_ID)
            LEFT OUTER JOIN IQMS.V_30_60_SUM V_30_60_SUM
            ON ARCUSTO.ID=V_30_60_SUM.ARCUSTO_ID)
          LEFT OUTER JOIN IQMS.V_60_90_SUM V_60_90_SUM
          ON ARCUSTO.ID=V_60_90_SUM.ARCUSTO_ID)
         LEFT OUTER JOIN IQMS.V_90_SUM V_90_SUM
         ON ARCUSTO.ID=V_90_SUM.ARCUSTO_ID)
       LEFT OUTER JOIN IQMS.V_CURRENT_SUM V_CURRENT_SUM
       ON ARCUSTO.ID=V_CURRENT_SUM.ARCUSTO_ID
ORDER BY
       ARCUSTO.CUSTNO,
       ARCUSTO.ID,
       ARCUSTO.COMPANY
HAVING SUM(Due) > ARCUST.CREDIT_LIMIT

Answer 1

你应该 post 你得到的确切错误，我在没有它的情况下做出假设..

你需要一个 GROUP BY 在那里......你的 HAVING 不能引用列别名..你需要重新声明完整的 SUM .. ORDER BY 排在最后。

所以你的最终作品应该是这样的：

  GROUP BY ARCUSTO.CUSTNO,
         ARCUSTO.COMPANY,
         ARCUSTO.ID,
         ARCUSTO.FAX_NUMBER,
         ARCUSTO.STATUS_ID,
         ARCUSTO.CREDIT_LIMIT,
         ARCUSTO.ADDR1,
         ARCUSTO.ADDR2,
         ARCUSTO.ADDR3,
         ARCUSTO.CITY,
         ARCUSTO.STATE,
         ARCUSTO.ZIP,
         ARCUSTO.COUNTRY,
         ARCUSTO.PHONE_NUMBER,
  HAVING SUM(V_1_30_SUM.LEFT_TO_APPLY, V_30_60_SUM.LEFT_TO_APPLY, V_60_90_SUM.LEFT_TO_APPLY, V_90_SUM.LEFT_TO_APPLY, V_CURRENT_SUM.LEFT_TO_APPLY)
              > ARCUST.CREDIT_LIMIT
  ORDER BY
         ARCUSTO.CUSTNO,
         ARCUSTO.ID,
         ARCUSTO.COMPANY

试试看是否效果更好，如果不行，请post完整准确的错误信息

SUM不支持多表达式。
子句的顺序为：WITH ... SELECT ... FROM ... WHERE ... GROUP BY ... HAVING ... ORDER BY ...。
如果有非聚合列，为了使用 HAVING 子句，您需要一个 GROUP BY 子句。
您不能在 WHERE 或 HAVING 子句中使用 SELECT 子句中定义的列别名。

类似于：

SELECT *
FROM   (
  SELECT A.*,
         COALESCE( ( SELECT SUM( LEFT_TO_APPLY ) FROM V_1_30_SUM WHERE A.ID = ARCUSTO_ID ), 0 )
           + COALESCE( ( SELECT SUM( LEFT_TO_APPLY ) FROM V_30_60_SUM   WHERE A.ID = ARCUSTO_ID ), 0 )
           + COALESCE( ( SELECT SUM( LEFT_TO_APPLY ) FROM V_60_90_SUM   WHERE A.ID = ARCUSTO_ID ), 0 )
           + COALESCE( ( SELECT SUM( LEFT_TO_APPLY ) FROM V_90_SUM      WHERE A.ID = ARCUSTO_ID ), 0 )
           + COALESCE( ( SELECT SUM( LEFT_TO_APPLY ) FROM V_CURRENT_SUM WHERE A.ID = ARCUSTO_ID ), 0 ) AS Due
  FROM   IQMS.ARCUSTO A
  ORDER BY
         A.CUSTNO,
         A.ID,
         A.COMPANY
)
WHERE Due > Credit_Limit;
