Question

所以我有一个SQL查询返回一组结果，如：

ID     Data1      Data2      Data3      Data4
1,     Null,      Null,      Null,      SomeValue
1,     Null,      Null,      SomeValue, Null
1,     Null,      SomeValue, Null,      Null
1,     SomeValue, Null,      Null,      Null
2,     Null,      Null,      Null,      SomeValue
2,     Null,      Null,      SomeValue, Null
2,     Null,      SomeValue, Null,      Null
2,     SomeValue, Null,      Null,      Null

我需要做的是将所有ID合并到同一个ID，然后生成2行完整数据：

ID       Data1           Data2           Data3           Data4
1,     SomeValue,      SomeValue,      SomeValue,      SomeValue
2,     SomeValue,      SomeValue,      SomeValue,      SomeValue

任何人都知道这是否可行？

我尝试使用GROUP BY，但它不允许我在select查询中拥有的其余值。

完整的SQL语句：

SELECT      
DISTINCT(D.DocumentNumber) AS [PTW No], 
D.ListCustomField1 AS [Work Order], 
D.ListAssetNumber AS [KKS No],
D.ListWorkToBeDone AS [Description],
D.CurrentStatusName AS [PTW Status],
D.TypeName AS [Section],
dbo.Sem_fn_PTWReport_ProcessData('AreaPicklist', MDP.Value, DCV.ValueString) AS [Area],
dbo.Sem_fn_PTWReport_ProcessData('IssueDate', MDP.Value, D.ID) AS [Actual Start Date], 
dbo.Sem_fn_PTWReport_ProcessData('CloseDate', MDP.Value, D.ID) AS [Actual Finished Date], 
dbo.Sem_fn_PTWReport_ProcessData('Duration', MDP.Value, D.ID) AS [Duration], 
dbo.Sem_fn_PTWReport_ProcessData('Impact', MDP.Value, DCV.ValueString) AS [Potential Non-Availability],
dbo.Sem_fn_PTWReport_ProcessData('DerationWater', MDP.Value, DCV.ValueString) AS [Deration - Water],
dbo.Sem_fn_PTWReport_ProcessData('DerationPower', MDP.Value, DCV.ValueString) AS [Deration - Power],
dbo.Sem_fn_PTWReport_ProcessData('DeclarationNumber', MDP.Value, DCV.ValueString) AS [Availability Decl No/ Rev No]

FROM dbo.Document AS D LEFT OUTER JOIN
     dbo.DocumentControlValues AS DCV ON D.ID = DCV.DocumentId LEFT OUTER JOIN
     dbo.MapperDocumentProperty AS MDP ON DCV.ControlId = MDP.DocumentControlMapperId
WHERE D.Stereotype = '1' 
AND CAST(MDP.Name AS nvarchar(max)) = 'FriendlyName'
AND CAST(MDP.Value AS nvarchar(max)) IN ('AreaP1_Picklist', 'ImpactAvailabilityP3_TextBlock',         'DerationWaterP1_TextBox', 'DerationPowerP1_TextBox', 'DerationDeclarationNoP1_TextBox')

欢迎帮助！

干杯，戴夫。

很抱歉这个混乱。这就是我试图建议的：

SELECT  (D.DocumentNumber) AS [PTW No], 
        MAX(D.ListCustomField1) AS [Work Order], 
        MAX(D.ListAssetNumber) AS [KKS No],
        MAX(D.ListWorkToBeDone) AS [Description],
        MAX(D.CurrentStatusName) AS [PTW Status],
        MAX(D.TypeName) AS [Section],
        MAX(dbo.Sem_fn_PTWReport_ProcessData('AreaPicklist', MDP.Value, DCV.ValueString)) AS [Area],
        MAX(dbo.Sem_fn_PTWReport_ProcessData('IssueDate', MDP.Value, D.ID)) AS [Actual Start Date], 
        MAX(dbo.Sem_fn_PTWReport_ProcessData('CloseDate', MDP.Value, D.ID)) AS [Actual Finished Date], 
        MAX(dbo.Sem_fn_PTWReport_ProcessData('Duration', MDP.Value, D.ID)) AS [Duration], 
        MAX(dbo.Sem_fn_PTWReport_ProcessData('Impact', MDP.Value, DCV.ValueString)) AS [Potential Non-Availability],
        MAX(dbo.Sem_fn_PTWReport_ProcessData('DerationWater', MDP.Value, DCV.ValueString)) AS [Deration - Water],
        MAX(dbo.Sem_fn_PTWReport_ProcessData('DerationPower', MDP.Value, DCV.ValueString)) AS [Deration - Power],
        MAX(dbo.Sem_fn_PTWReport_ProcessData('DeclarationNumber', MDP.Value, DCV.ValueString)) AS [Availability Decl No/ Rev No]
FROM    dbo.Document AS D LEFT OUTER JOIN
        dbo.DocumentControlValues AS DCV ON D.ID = DCV.DocumentId LEFT OUTER JOIN
        dbo.MapperDocumentProperty AS MDP ON DCV.ControlId = MDP.DocumentControlMapperId
WHERE   D.Stereotype = '1' 
        AND CAST(MDP.Name AS nvarchar(max)) = 'FriendlyName'
        AND CAST(MDP.Value AS nvarchar(max)) IN 
        (
            'AreaP1_Picklist',
            'ImpactAvailabilityP3_TextBlock',
            'DerationWaterP1_TextBox',
            'DerationPowerP1_TextBox',
            'DerationDeclarationNoP1_TextBox'
        )
GROUP BY (D.DocumentNumber)

SQL合并具有相同ID的行
