Question

我正在使用SQL Server 2012。我有以下查询从几个不同的视图中提取各种字段。每当ContentSetName列中有新组时，查询就会动态插值三个不同的值。另请注意，Cover的值仅在每组中出现一次。这一切都运行正常，但我现在需要更改ContentSetName列中用于report_SSRS的硬编码值以使用动态派生值。请参阅此前有关此查询的Stackoverflow帖子

Dynamically interpolate extra rows in SQL query

此后，查询已演变为：

WITH Data AS
(   SELECT b.ReportHeading1, 
            bb.ReportHeading1 as RepHeading1,
            bb.ReportHeading2 as RepHeading2,
            bb.ReportHeading3 as RepHeading3,
            p.DisplayOrder, 
            p.MemberCode,
            m.PortfolioGroupCode as DistGroup,
            m.MemberCode as Packgroup,
            g.purpose,
            p.PortfolioGroupID as pid,
            m.PortfolioGroupID as mid,
            lb.value as repset,
            RowNumber = ROW_NUMBER() OVER(PARTITION BY p.portfoliogroupid ORDER BY p.DisplayOrder)
    FROM    [APXFirm].[AdvApp].[vPortfolioGroupMemberFlattened] p
                LEFT OUTER JOIN [APXFirm].[AdvApp].[vPortfolioBase] b
                ON b.PortfolioBaseID = p.PortfolioGroupID
                LEFT OUTER JOIN  [APXFirm].[AdvApp].[vPortfolioBase] bb
                ON bb.PortfolioBaseID = p.MemberID
                LEFT OUTER JOIN [APXFirm].[AdvApp].[vPortfolioGroupMember] m
                 on m.MemberID = p.PortfolioGroupID
                LEFT OUTER JOIN [APXFirm].[AdvApp].[vPortfolioGroup] g
                ON g.PortfolioGroupID = m.PortfolioGroupID
                LEFT OUTER JOIN [APXFirm].[AdvApp].[vPortfolioBaseLabels] lb
                on p.MemberID = lb.PortfolioBaseID
                WHERE     m.PortfolioGroupCode like '%_Dist%'
                and (g.Purpose like '%_ind' or g.Purpose like '%_group')
                and lb.Label = '$repset'

       )
SELECT
d.repset,
d.DistGroup,
d.Packgroup,
t.ContentSetName,
    CONCAT(d.pid,'_',d.DisplayOrder,'_',t.ContentSetName,'_') as DistributionName,
        CONCAT(d.RepHeading1,'_',d.RepHeading2,'_', d.RepHeading3) as DistributionCustom,
    'False' as IsForFunctionalGroup,
    'True' as IsLandscapePageNum,
    1 as NumOfCopies,
    d.purpose as RecipientCode,
    d.ReportHeading1 as RecipientFullName,
    d.MemberCode as ReportingEntityCode,
    'Daily' as RunEvent
    FROM    Data d
        CROSS JOIN 
        (   VALUES
                ('Cover_SSRS'),
                ('Separator_docx'),
                ('Report_SSRS')
        ) t (ContentSetName)
WHERE   d.RowNumber = 1
OR      t.ContentSetNAme != 'Cover_SSRS'

这将生成以下样本结果集。

这是期望的结果集

当前和期望结果集之间的差异是，不是第三个插值行的静态值“Report_SSRS”，而是想要拉出d.repset的值，在本例中，d.repset的值在DVAAnnual，DVAValues和DVAStandard之间变化。

我还在DistributionName列中连接d.repset列（当前为t.contentsetname），并希望使用d.repset的值而不是Report_SSRS的硬编码值。

谢谢

我认为您只需将查询更改为：

WITH Data AS
(   SELECT b.ReportHeading1, 
            bb.ReportHeading1 as RepHeading1,
            bb.ReportHeading2 as RepHeading2,
            bb.ReportHeading3 as RepHeading3,
            p.DisplayOrder, 
            p.MemberCode,
            m.PortfolioGroupCode as DistGroup,
            m.MemberCode as Packgroup,
            g.purpose,
            p.PortfolioGroupID as pid,
            m.PortfolioGroupID as mid,
            lb.value as repset,
            RowNumber = ROW_NUMBER() OVER(PARTITION BY p.portfoliogroupid ORDER BY p.DisplayOrder)
    FROM    [APXFirm].[AdvApp].[vPortfolioGroupMemberFlattened] p
                LEFT OUTER JOIN [APXFirm].[AdvApp].[vPortfolioBase] b
                ON b.PortfolioBaseID = p.PortfolioGroupID
                LEFT OUTER JOIN  [APXFirm].[AdvApp].[vPortfolioBase] bb
                ON bb.PortfolioBaseID = p.MemberID
                LEFT OUTER JOIN [APXFirm].[AdvApp].[vPortfolioGroupMember] m
                 on m.MemberID = p.PortfolioGroupID
                LEFT OUTER JOIN [APXFirm].[AdvApp].[vPortfolioGroup] g
                ON g.PortfolioGroupID = m.PortfolioGroupID
                LEFT OUTER JOIN [APXFirm].[AdvApp].[vPortfolioBaseLabels] lb
                on p.MemberID = lb.PortfolioBaseID
                WHERE     m.PortfolioGroupCode like '%_Dist%'
                and (g.Purpose like '%_ind' or g.Purpose like '%_group')
                and lb.Label = '$repset'

       )
SELECT
d.repset,
d.DistGroup,
d.Packgroup,
t.ContentSetName,
    CONCAT(d.pid,'_',d.DisplayOrder,'_',t.ContentSetName,'_') as DistributionName,
        CONCAT(d.RepHeading1,'_',d.RepHeading2,'_', d.RepHeading3) as DistributionCustom,
    'False' as IsForFunctionalGroup,
    'True' as IsLandscapePageNum,
    1 as NumOfCopies,
    d.purpose as RecipientCode,
    d.ReportHeading1 as RecipientFullName,
    d.MemberCode as ReportingEntityCode,
    'Daily' as RunEvent
    FROM    Data d
        CROSS APPLY 
        (   VALUES
                ('Cover_SSRS'),
                ('Separator_docx'),
                (d.repset)
        ) t (ContentSetName)
WHERE   d.RowNumber = 1
OR      t.ContentSetNAme != 'Cover_SSRS'

区别在于使用：

CROSS JOIN 
(   VALUES
        ('Cover_SSRS'),
        ('Separator_docx'),
        ('Report_SSRS')
) t (ContentSetName)

已更改为

CROSS APPLY 
(   VALUES
        ('Cover_SSRS'),
        ('Separator_docx'),
        (d.repset)
) t (ContentSetName)

通过使用CROSS APPLY，您仍然可以访问查询中的所有字段，而不是CROSS JOIN。

更改查询以包括派生数据而不是硬编码数据
