Question

在选择列表中，获取列'CM.PfmFolder.Id'无效，因为该列未包含在聚合函数或GROUP BY子句中。 请提出如何重新构造此查询

 SELECT                     
 F.Id                    
,F.FolderNo                    
,F.FolderStatusDate
,(SELECT CodeDesc FROM CM.CodeTable WHERE Id = F.FolderStatusCode) 'FolderStatus'                    
,(SELECT CodeDesc FROM CM.CodeTable WHERE Id = F.FolderLocationCode) 'Location'                    
,F.Volume                    
,F.SDExhibits                    
,F.Cost                    
,F.Remarks                    
 FROM CM.PfmFolder F WITH(NOLOCK, INDEX(IX)) INNER JOIN                    
(                    
 CM.PfmFolderMstIpMap MAP WITH(NOLOCK, INDEX(ix_FF))                  
 INNER JOIN  CM.MstIp IP WITH(NOLOCK) ON MAP.MstIpFK = IP.Id                   
 AND IP.RegistryCode = @RegistryCode                    
 AND IP.DeletedBy IS NULL                      
 AND MAP.DeletedBy IS NULL                      
)                    
ON MAP.PfmFolderFK = F.Id                    
AND F.DeletedBy IS NULL      
AND (

  OR F.FolderLocationCode = @FolderLocationCode                    
 )                    
AND (                    
  @FolderStatusCode IS NULL                    
  OR @FolderStatusCode = @GUID_EMPTY                    
  OR F.FolderStatusCode = @FolderStatusCode                    
 )
 GROUP BY F.Id

Answer 1

您必须对ID以外的其他列使用聚合函数，才能为每个分组的F.Id获取不同的值。

您也可以使用排名功能来做到这一点：

尝试这个

SELECT * FROM
(
SELECT                     
 F.Id                    
,F.FolderNo                    
,F.FolderStatusDate
,(SELECT CodeDesc FROM CM.CodeTable WHERE Id = F.FolderStatusCode) 'FolderStatus'                    
,(SELECT CodeDesc FROM CM.CodeTable WHERE Id = F.FolderLocationCode) 'Location'                    
,F.Volume                    
,F.SDExhibits                    
,F.Cost                    
,F.Remarks,
Row_number() OVER(partition BY F.Id  ORDER BY (SELECT NULL) ASC) RN              
 FROM CM.PfmFolder F WITH(NOLOCK, INDEX(IX)) INNER JOIN                    
(                    
 CM.PfmFolderMstIpMap MAP WITH(NOLOCK, INDEX(ix_FF))                  
 INNER JOIN  CM.MstIp IP WITH(NOLOCK) ON MAP.MstIpFK = IP.Id                   
 AND IP.RegistryCode = @RegistryCode                    
 AND IP.DeletedBy IS NULL                      
 AND MAP.DeletedBy IS NULL                      
)                    
ON MAP.PfmFolderFK = F.Id                    
AND F.DeletedBy IS NULL      
AND (                    
 F.FolderStatusDate >= @FolderStatusDateFrom                    
 AND F.FolderStatusDate < @FolderStatusDateTo                    
 )                    
AND (                    
  @FolderLocationCode IS NULL                    
  OR @FolderLocationCode = @GUID_EMPTY                    
  OR F.FolderLocationCode = @FolderLocationCode                    
 )                    
AND (                    
  @FolderStatusCode IS NULL                    
  OR @FolderStatusCode = @GUID_EMPTY                    
  OR F.FolderStatusCode = @FolderStatusCode                    
 )
) AS T
Where RN = 1

您还可以检查加入条件，并确保它们给出了不同的结果。 这些重复可能是由这些情况引起的。
