Question

我有以下Postgres代码，我希望Group BY "Personal CC"，但由于显而易见的原因，我无法对聚合字段执行此操作。

如果我没有放Group BY，那么我会收到错误的"Number of Assistant Supervisors in Same Month" Personal CC。

请帮我详细说明如何计算金额。是的，我做了一些研究，并且知道我们可以使用INNER JOIN，但我失败了。

期望的结果应该是降序中的个人CC总和
总和应仅适用于我在下面给出的月份和年份，但是它需要整年的价值观是错误的
如果没有，我只需要将个人CC的总和包括在内请给我们一个解决方案，如何通过不包括来获得总和它在Group BY
我没有阅读文档，但我一直在研究 IT

对于每个赞助商，我有各个国家的每月cc。个人CC值。每个月。我想总结它们以获得一个独特的总结值

 SELECT 
        extended_downline."Sponsor FBO ID"
        ,extended_downline."Sponsor Name"
        ,mcc.processing_month__c AS "Processing Month"
        ,mcc.processing_year__c AS "Processing Year"

        ,sum(mcc.personal_cc_mtd__c) AS "Personal CC"
        ,sum("Same Month") as "Number of Assistant Supervisors in Same Month"
        ,bool_or(mcc.current_month_active__c) AS "Current Month Active"

    FROM extended_downline
    LEFT OUTER JOIN connect.monthly_cc__c mcc ON mcc.distributor__c = extended_downline.sponsor_distributor__c
        AND mcc.op_company__c = extended_downline."Operating Company"
        AND (
            (
                mcc.processing_year__c = '2017'
                AND mcc.processing_month__c = 10
                )
            )
    WHERE extended_downline."Same Month" <> 0
        AND extended_downline."Generation" <> 0
        AND mcc.personal_cc_mtd__c IS NOT NULL
    GROUP BY
        extended_downline."Sponsor FBO ID"
        ,extended_downline."Sponsor Name"    
        ,mcc.processing_year__c
        ,mcc.processing_month__c
        ,mcc.personal_cc_mtd__c
        ,extended_downline."Same Month"

    ORDER BY "Personal CC" DESC LIMIT 20

您可以使用Order By ColumnPosition

例如：
