如何在 SQL(toad) 中添加两个具有基于年份的金额总和的表格？

Question

第一个 Table :

SELECT A.BU,A.PROJECT,SUM(A.BUDGET_AMOUNT),SUBSTR(A.BUDGET_PERIOD,3,2)
FROM BUDGET_SUMMARY A
GROUP BY A.BU,A.PROJECT,SUBSTR(A.BUDGET_PERIOD,3,2)

第二个table：

SELECT B.BU,A.PROJECT,SUM(B.ACTUAL_AMOUNT),SUBSTR(B.ACTUAL_PERIOD,3,2)
FROM ACTUAL_SUMMARY B
GROUP BY B.BU,B.PROJECT,SUBSTR(B.ACTUAL_PERIOD,3,2)

现在，我想以

的形式将上述两个table合并为一个table

BU|PROJECT|SUM(BUDGET_AMOUNT)|SUBSTR(A.BUDGET_PERIOD,3,2)|SUM(B.ACTUAL_AMOUNT)|SUBSTR(B.ACTUAL_PERIOD,3,2)

Answer 1

SELECT A.BU,A.PROJECT, SUM(A.BUDGET_AMOUNT), SUBSTR(A.BUDGET_PERIOD,3,2), SUM(B.ACTUAL_AMOUNT)
FROM BUDGET_SUMMARY A
GROUP BY A.BU,A.PROJECT,SUBSTR(A.BUDGET_PERIOD,3,2)

或者两个 table 的值不同，您可以使用 JOIN（用于匹配值的内部联接）

    SELECT A.BU,A.PROJECT,SUM(A.BUDGET_AMOUNT),SUBSTR(A.BUDGET_PERIOD,3,2), T.SUM_BUDGET_AMOUNT, T.SUB_ACTUAL_PERIOD
    FROM BUDGET_SUMMARY A
    INNER JOIN  (
        SELECT B.BU,A.PROJECT,SUM(B.ACTUAL_AMOUNT) sum_BUDGET_AMOUNT,SUBSTR(B.ACTUAL_PERIOD,3,2) SUB_ACTUAL_PERIOD
        FROM ACTUAL_SUMMARY B
        GROUP BY B.BU,B.PROJECT,SUBSTR(B.ACTUAL_PERIOD,3,2)
        ) T  ON T.BU = A.BY 
            AND T.PROJECT = A.PROJECT,SUBSTR(A.BUDGET_PERIOD,3,2)
                AND T.SUB_ACTUAL_PERIOD = ,SUBSTR(A.BUDGET_PERIOD,3,2)
    GROUP BY A.BU,A.PROJECT,SUBSTR(A.BUDGET_PERIOD,3,2)

如果您有 aprtila 匹配项，请左加入

    SELECT A.BU,A.PROJECT,SUM(A.BUDGET_AMOUNT),SUBSTR(A.BUDGET_PERIOD,3,2), T.SUM_BUDGET_AMOUNT, T.SUB_ACTUAL_PERIOD
    FROM BUDGET_SUMMARY A
    LEFT  JOIN  (
        SELECT B.BU,A.PROJECT,SUM(B.ACTUAL_AMOUNT) sum_BUDGET_AMOUNT,SUBSTR(B.ACTUAL_PERIOD,3,2) SUB_ACTUAL_PERIOD
        FROM ACTUAL_SUMMARY B
        GROUP BY B.BU,B.PROJECT,SUBSTR(B.ACTUAL_PERIOD,3,2)
        ) T  ON T.BU = A.BY 
            AND T.PROJECT = A.PROJECT,SUBSTR(A.BUDGET_PERIOD,3,2)
                AND T.SUB_ACTUAL_PERIOD = ,SUBSTR(A.BUDGET_PERIOD,3,2)
    GROUP BY A.BU,A.PROJECT,SUBSTR(A.BUDGET_PERIOD,3,2)

Answer 2

纯属猜测，您的描述难以阅读且不可执行。命名子查询应该有助于获得您想要的结果（假设“项目”可以用作连接列）

with budget as
(
SELECT A.BU,A.PROJECT,SUM(A.BUDGET_AMOUNT) sum_amount,SUBSTR(A.BUDGET_PERIOD,3,2) m_period FROM BUDGET_SUMMARY A GROUP BY A.BU,A.PROJECT,SUBSTR(A.BUDGET_PERIOD,3,2)
), actual as
(
SELECT B.BU,B.PROJECT,SUM(B.ACTUAL_AMOUNT) sum_amount,SUBSTR(B.ACTUAL_PERIOD,3,2) m_period FROM ACTUAL_SUMMARY B GROUP BY B.BU,B.PROJECT,SUBSTR(B.ACTUAL_PERIOD,3,2)
)

select  budget.BU,budget.PROJECT,budget.sum_amount,budget.m_period,actual.sum_amount,actual.m_period
from budget
join actual on budget.project=actual.project
