我有一个相当复杂的 PIVOT 查询，可能应该分成几部分。我的问题是我最终需要删除重复的行。

        SELECT 
        PostName,
        ActivityID,
        ProjectName,
        ProjectID,
        ObjectiveID,
        ObjectiveName,
        LastName,
        FirstName,
        VolID,
        Orgs,
        Coms,
        ISNULL([Males 0-9], 0) [Males 0-9], 
        ISNULL([Males 10-17], 0) [Males 10-17], 
        ISNULL([Males 18-24], 0) [Males 18-24], 
        ISNULL([Males 25+], 0) [Males 25+], 
        ISNULL([Females 0-9], 0) [Females 0-9], 
        ISNULL([Females 10-17], 0) [Females 10-17], 
        ISNULL([Females 18-24], 0) [Females 18-24], 
        ISNULL([Females 25+], 0) [Females 25+]
    FROM 
    (
        SELECT

            o.ObjectiveName,
            a.LastName,
            a.FirstName,
            a.VolID,
            ISNULL(COUNT(DISTINCT ac1.ActivityCollaboratorID), 0) AS Orgs,
            ISNULL(COUNT(DISTINCT ac2.ActivityCollaboratorID), 0) AS Coms,
            p.AddInd,

                LEFT JOIN [PCVRT].[dbo].[ActivityParticipants] p
                    ON a.ActivityID = p.ActivityID
                        AND a.GroupName IS NOT NULL
                        AND a.MMED <> 1
                FULL OUTER JOIN [PCVRT].[dbo].Buckets b
                    ON 
                        b.BucketID = p.BucketID
                        AND b.BucketSetID = 
                        (
                            SELECT BucketSetID FROM [PCVRT].[dbo].BucketSets
                            WHERE Name = 'Standard'
                        )
                LEFT JOIN PCVRT.dbo.Objectives o
                    ON o.ObjectiveID = ao.ObjectiveID
                LEFT JOIN PCVRT.dbo.ActivityCollaborators ac1
                    ON a.ActivityID = ac1.ActivityID
                        AND ac1.CollaboratorTypeID = 1
                LEFT JOIN PCVRT.dbo.ActivityCollaborators ac2
                    ON a.ActivityID = ac2.ActivityID
                        AND ac2.CollaboratorTypeID = 2
                LEFT JOIN PCVRT.dbo.Projects pr
                    ON pr.ProjectID = a.ProjectId
        GROUP BY
            a.ActivityID,
            a.PostName,
            pr.PostID,
            pr.ProjectName,
            pr.ProjectID,
            o.ObjectiveID,
            o.ObjectiveName,
            a.LastName,
            a.FirstName,
            a.VolID,
            p.AddInd,
            b.Name

    ) AS source
    PIVOT
    (
        MAX(AddInd)
        FOR Name IN([Males 0-9], [Males 10-17], [Males 18-24], [Males 25+], [Females 0-9], [Females 10-17], [Females 18-24], [Females 25+])
    ) AS pvt
    WHERE ProjectName IS NOT NULL
        AND ObjectiveName IS NOT NULL
    ORDER BY 
        ProjectID,
        ObjectiveID,
        ProjectName,
        ObjectiveName,
        LastName,
        FirstName

所以，这样的结果是这样的：

所以，我需要的是每个项目-> 目标配对只获得一行，汇总活动。

想法？

您没有提供您想要的最终结果，但是根据您当前的结果，我对问题所在进行了一些猜测。

当您应用 PIVOT 函数时，您应该只包含实际需要在最终结果中显示的列，因为选择列表中不属于聚合函数或 PIVOT 列的所有列都将被分组。

您当前的数据具有该列的多个值，ObjectiveId因此当您包含该列时，您将在最终结果中显示多行。

我猜您应该使用类似于以下内容的内容：

SELECT 
    PostName,
    ActivityID,
    ProjectName,
    ProjectID,
    ObjectiveName,
    LastName,
    FirstName,

    ISNULL([Males 10-17], 0) [Males 10-17], 
    ISNULL([Males 18-24], 0) [Males 18-24], 
    ISNULL([Males 25+], 0) [Males 25+], 
    ISNULL([Females 0-9], 0) [Females 0-9], 
    ISNULL([Females 10-17], 0) [Females 10-17], 
    ISNULL([Females 18-24], 0) [Females 18-24], 
    ISNULL([Females 25+], 0) [Females 25+]
