我有一个带有多个SUMs 的查询，它给我的值比我预期的要高。如果我将查询缩减为一个SUM，一切正常，但只要我添加其他SUMs，我就会得到不正确的值。我尝试在网上查找并尝试了不同的方法，包括更改JOINs 和 nested SELECTs，但仍然没有运气。所有帮助将不胜感激。

SELECT
    A.WR_NO WORK_ORDER, A.WR_TYPE_CODE WR_TYPE, B.NAME PLANNER, A.SCHEDULING_POLYGON_CODE AREA, A.FINAL_CLOSE_DATE COMPLETION_DATE, C.ACTUAL_ITEM_AMT EST_ENG,
    SUM(D.AFTER_COND_FCT_AMT) EST_CREW, SUM(E.AFTER_COND_FCT_AMT) ASB_CREW, SUM(F.AFTER_COND_FCT_AMT) EST_CONTR, SUM(G.AFTER_COND_FCT_AMT) ASB_CONTR
FROM
    WORK_REQUEST A, CC.ALL_PEOPLE B, WR_CONTRIBUTION_VOUCHER C, WR_COST_ESTIMATE D, WR_COST_ESTIMATE E, WR_COST_ESTIMATE F, WR_COST_ESTIMATE G
WHERE
    (A.FINAL_CLOSE_DATE BETWEEN TO_DATE ('10/01/2012','MM/DD/YYYY') AND TO_DATE ('10/04/2012','MM/DD/YYYY'))
    AND A.ENTRY_PERSON_NO = B.PERSON_NO(+)
    AND A.WR_NO = C.WR_NO(+)
    AND A.WR_NO = D.WR_NO(+)
    AND A.WR_NO = E.WR_NO(+)
    AND A.WR_NO = F.WR_NO(+)
    AND A.WR_NO = G.WR_NO(+)
    AND (C.VOUCHER_CNTRB_TYPE_CODE(+) = 'ENGT')
    AND (D.COST_TYPE_CODE(+) = 'LAB' AND D.DESIGN_ASBUILT_DA(+) = 'D' AND   D.PROVIDER(+) = 'CO')
    AND (E.COST_TYPE_CODE(+) = 'LAB' AND E.DESIGN_ASBUILT_DA(+) = 'A' AND   E.PROVIDER(+) = 'CO')
    AND (F.COST_TYPE_CODE(+) = 'LAB' AND F.DESIGN_ASBUILT_DA(+) = 'F' AND   F.PROVIDER(+) = 'CN')
    AND (G.COST_TYPE_CODE(+) = 'LAB' AND G.DESIGN_ASBUILT_DA(+) = 'G' AND   G.PROVIDER(+) = 'CN')
GROUP BY
    A.WR_NO, A.WR_TYPE_CODE, B.NAME, A.SCHEDULING_POLYGON_CODE, A.FINAL_CLOSE_DATE,     C.ACTUAL_ITEM_AMT
ORDER BY 1

您获得的值比您预期的要高，因为连接是乘以行的。如果不了解数据结构，外部人员很难准确地告诉您问题出在哪里。

该问题的解决方案是只在计算它所需的表格上进行求和。然后，您可以在该点之后加入其他表/摘要。

顺便说一句，你真的应该使用正确的JOIN语法。使用逗号来表示连接已经过时了，并且使查询更难理解。
