Question

我正在关注我在这里提出的问题：SumIF in SQL Access

我有3张桌子[经纪人]，[OPT]，[TRS]。 [经纪人]有2个字段BRKR_CODE, Status和[OPT]和[TRS]有5个相同字段BRKR1, BRKR2, Date, COM_BRK1, COM_BRKR2

OPT.BRKR1，OPT.BRKR2，TRS.BRKR1，TRS.BRKR2与Broker.BRKR_CODE相关联且可以相等。

我想写这个查询....如果Broker.Status="Active"那么选择Broker.BRKR_CODE 然后对于每个Broker.BRKR_CODE（例如“CB”），当OPT.COM_BRKR1时OPT.BRKR1="CB" + OPT.COM_BRKR2的总和OPT.BRKR2="CB"时，TRS.COM_BRKR1的总和在TRS.BRKR1="CB"

时TRS.COM_BRKR2 + TRS.BRKR2="CB"的总和时BRKR_CODE

我使用前一个问题中得到的答案编写了这段代码...但仍然存在语法问题...基本上我想要一个包含3列OPT_Tot，TRS_Tot，{的数组{1}}

SELECT Broker.BRKR_CODE,
       Sum(OPT.COM_BRKR1)+ Sum(OPT.COM_BRKR2) AS OPT_Tot,
       Sum(TRS.COM_BRKR1)+ Sum(TRS.COM_BRKR2) AS TRS_Tot
FROM Broker 
     INNER JOIN  OPT
     ON (Broker.BRKR_CODE = OPT.BRKR2) OR (Broker.BRKR_CODE = OPT.BRKR1)
      INNER JOIN  TRS
     ON (Broker.BRKR_CODE = TRS.BRKR2) OR (Broker.BRKR_CODE = TRS.BRKR1)
WHERE Broker.Status = "Active"
GROUP BY Broker.BRKR_CODE

您应该尝试在设计器中进行此查询（只是为了使基本连接正确）。您将看到Access使用其他SQL引擎不做的括号做了一些不同的事情。

您需要将每组连接包装在括号中

SELECT Broker.BRKR_CODE,
       Sum(OPT.COM_BRKR1)+ Sum(OPT.COM_BRKR2) AS OPT_Tot,
       Sum(TRS.COM_BRKR1)+ Sum(TRS.COM_BRKR2) AS TRS_Tot
FROM (Broker 
     INNER JOIN  OPT
     ON (Broker.BRKR_CODE = OPT.BRKR2) OR (Broker.BRKR_CODE = OPT.BRKR1))
      INNER JOIN  TRS
     ON (Broker.BRKR_CODE = TRS.BRKR2) OR (Broker.BRKR_CODE = TRS.BRKR1)
WHERE Broker.Status = "Active"
GROUP BY Broker.BRKR_CODE
