Question

我根据需要运行第一个查询。此查询按周将用户的活动级别聚合到相应的BusinessIds中。

出于报告目的，我需要创建一个新列，用于捕获每个Grouped Week和BusinessId的活动级别大于0的UserId数。第二个查询自己给了我正确的值（尽管它可能有比合并后所需的数据点更多的数据点），但是我很难将它合并到我的第一个查询中。

这可能是一项非常直接的努力，但我无法从其他问题的样本中找到答案。任何帮助表示赞赏。

如果您想在一个声明中执行此操作，可以使用CTE。

SET DATEFIRST 2;
WITH cte1 AS (
    /* First Query */
    SELECT  SUM(fua.[RisksAffected] + fua.[IssuesAffected] + fua.[ChangesAffected]) AS RIC,
            SUM(fua.[ProjectsCreated] + fua.[ProjectsAffected]) AS Projects,
            CASE WHEN SUM(fua.[ProjectsCreated]) > 0 THEN CAST(1 AS BIT)
                 ELSE CAST(0 AS BIT)
            END AS ProjectCreated,
            SUM(fua.[TimesheetsCreated]) AS Timesheets,
            SUM(fua.[ReportsAffected]) AS Reports,
            SUM(fua.[FilesAffected]) AS Files,
            ud.[BusinessId],
            COUNT(DISTINCT fua.UserId) AS [UserCount],
            DATEADD(day,-1 * DATEPART(dw,fua.[QueryDate]),fua.[QueryDate]) AS [ActivityDate]
    FROM    [client_projectmanager].[whs].[FactUserActivity] fua
            LEFT JOIN [client_projectmanager].[whs].[DimUserDataV2] ud ON fua.[UserId] = ud.[UserId]
    GROUP BY DATEADD(day,-1 * DATEPART(dw,fua.[QueryDate]),fua.[QueryDate]),
            ud.[BusinessId]
),
cte2 AS (
    /* Second Query */
    SELECT  COUNT(DISTINCT sela.UserId),
            sela.BusinessId,
            DATEADD(day,-1 * DATEPART(dw,sela.[Date]),sela.Date)
    FROM    (SELECT fua.UserId,
                    ud.BusinessId,
                    DATEADD(day,-1 * DATEPART(dw,fua.[QueryDate]),fua.[QueryDate]) AS [Date],
                    SUM(fua.[RisksAffected] + fua.[IssuesAffected] + fua.[ChangesAffected] + fua.[ProjectsCreated] + [ProjectsAffected]) AS Acttotal
             FROM   [client_projectmanager].[whs].[FactUserActivity] fua
                    LEFT JOIN [client_projectmanager].[whs].[DimUserDataV2] ud ON fua.[UserId] = ud.[UserId]
             GROUP BY DATEADD(day,-1 * DATEPART(dw,fua.[QueryDate]),fua.[QueryDate]),
                    fua.[UserId],
                    ud.BusinessId
             HAVING SUM(fua.[RisksAffected] + fua.[IssuesAffected] + fua.[ChangesAffected] + fua.[ProjectsCreated] + fua.[ProjectsAffected]) > 0
            ) sela
    GROUP BY DATEADD(day,-1 * DATEPART(dw,sela.[Date]),sela.Date),
            sela.BusinessId
    ORDER BY DATEADD(day,-1 * DATEPART(dw,sela.[Date]),sela.Date)
)
SELECT  *
FROM    cte1
        -- USE INNER JOIN IF YOU WANT ONLY RECORDS THAT EXIST IN BOTH
        LEFT JOIN cte2 ON cte1.BusinessId = cte2.BusinessId
                     AND cte1.ActivityDate = cte2.GroupedByDateName

您的第二个查询缺少列别名..假设您正在加入BusinessId的2个查询和您分组的日期，则需要添加列别名

需要帮助将第二个查询合并到第一个查询中
