我使用 Oracle 10g 并在 Packages 中查询。如何在 Packages 中透视函数 sum()？

Sql 查询。

WITH DATA_JOIN AS
 (SELECT S.START_DATE_GMT,
         S.NO_OF_CALL,
         S.RATE,
         T.TAX_RATE,
         T.EFF_DATE,
         T.EXP_DATE,
         S.COMPANY_CODE,
         T.COMPANY_CODE CC,
         S.SUB_EVENT_TYPE_ID,
         S.event_type_id,
         S.PMN_ORIGIN,
         S.PMN_ROUTE
    FROM IR_V_ISM_RATE_BY_TRANS S
    LEFT JOIN IR_PMN_TAX T
      ON S.COMPANY_CODE = T.COMPANY_CODE
     AND S.PMN_ROUTE = T.PMN_CODE
   WHERE T.TAX_TYPE = '01'
     AND S.START_DATE_GMT <= T.EFF_DATE
     AND S.START_DATE_GMT >= T.EXP_DATE
      OR T.EXP_DATE IS NULL
   ORDER BY COMPANY_CODE),
TEMP_A AS
 (SELECT START_DATE_GMT,
         SUM(NO_OF_CALL) AS TOTAL_TRANSACTION,
         ((SUM(NO_OF_CALL)) * RATE) AS TOTAL_AMOUNT,
         ((((SUM(NO_OF_CALL)) * RATE) * TAX_RATE) / 100) AS TOTAL_VAT,
         RATE
    FROM DATA_JOIN
   WHERE COMPANY_CODE = 'RIT' 
     AND SUB_EVENT_TYPE_ID = '2'
     AND PMN_ROUTE = 'C2' 
     AND EVENT_TYPE_ID = '01'
     AND TO_CHAR(START_DATE_GMT, 'MM/YYYY') <= '01/2015'
     AND (TO_CHAR(START_DATE_GMT, 'MM/YYYY') >= '01/2015' OR START_DATE_GMT IS NULL) 
   GROUP BY START_DATE_GMT, SUB_EVENT_TYPE_ID, RATE, TAX_RATE
   ORDER BY START_DATE_GMT)

/* Result */
 SELECT 
 SUM(TOTAL_AMOUNT)AS EXCLUDE_VAT,
 SUM(TOTAL_VAT) AS SUM_VAT,
 SUM(SUM(TOTAL_AMOUNT)+SUM(TOTAL_VAT)) AS TOTAL_INCLUDE
FROM TEMP_A
GROUP BY TOTAL_AMOUNT,TOTAL_VAT;

结果 SQL 查询

EXCLUDE_VAT | SUM_VAT | TOTAL_INCLUDE
5.50        | 0.30    | 5.80

我需要结果透视图

Calculate Vat   | Total Amount
----------------------------------
EXCLUDE_VAT     | 5.50
SUM_VAT         | 0.30
TOTAL_INCLUDE   | 5.80

如何在包中枢转函数 Sum()？

【参考方案1】：

您需要 unpivot，而不是 pivot，但 10g 本身不支持。有办法做到这一点，as shown here with decode，但在这种情况下，由于您已经拥有 CTE，您可以将三个查询联合起来：

/* Result */
SELECT 'EXCLUDE_VAT' AS CALCULATE_VAT,
  SUM(TOTAL_AMOUNT) AS TOTAL_AMOUNT
FROM TEMP_A
UNION ALL
SELECT 'TOTAL_VAT', SUM(TOTAL_VAT)
FROM TEMP_A
UNION ALL
SELECT 'TOTAL_INCLUDE', SUM(TOTAL_AMOUNT)+SUM(TOTAL_VAT)
FROM TEMP_A;

【参考方案2】：

我现在无法访问 Oracle 数据库，但我记得将 PIVOT 与 WITH 语句一起使用是有限制的。我可能错了。

select * from (
    select 1 AS CV_ORDER,
       'EXCLUDE_VAT' as CALCULATE_VAT,
       SUM(TOTAL_AMOUNT) as TOTAL_AMOUNT
    from TEMP_A group by 1, 'EXCLUDE_VAT'
    union all
    select 2 as CV_ORDER,
        'SUM_VAT' as CALCULATE_VAT,
         SUM(TOTAL_VAT) as TOTAL_AMOUNT
     from TEMP_A group by 2, 'SUM_VAT'
    union all
    select 3 as CV_ORDER,
        'TOTAL_INCLUDE' as CALCULATE_VAT,
        SUM(TOTAL_AMOUNT) + SUM)(TOTAL_VAT) as TOTAL_AMOUNT
        from TEMP_A group by 3, 'TOTAL_INCLUDE'
    ) order by CV_ORDER
