I have to join multiple tables in a SQL Server database in order to use the fields in Report Builder. This SQL query is ran as a stored procedure. The problem is that it is returning multiple rows that I consider duplicates.

Here is my query (some structure parts were taken out): 

 ALTER PROCEDURE [dbo].[GetRollCallData] 
    @Ids        VARCHAR(255),
    @LexiconId  INT,
    @UUID       UNIQUEIDENTIFIER,
    @ReadOnly   INT
 AS


 DECLARE @TableCode INT
 SET @TableCode = 58


        EXEC InsertInSelectionCache @Ids, @UUID, @TableCode, 0

            SELECT [File].*, FileType2Lexicon.Label as FileTypeLabel, [People].DefaultPhone, CFV.Value as DOA, CFV.CustomRecordsetId
                FROM FileType2Lexicon, SelectionCache, [People], [File]
                INNER JOIN [CustomRecordSet]
                ON [CustomRecordset].RecordId = [File].Id
                INNER JOIN (SELECT Value, CustomFieldId, CustomRecordsetId FROM [CustomFieldValue]) CFV
                ON  [CustomRecordset].Id = CFV.CustomRecordsetId
                INNER JOIN (SELECT CustomFieldId, Label FROM [CustomField2Lexicon]) CF2L
                ON CF2L.CustomFieldId = CFV.CustomFieldId
                WHERE   [File].Id = SelectionCache.RecordId
                AND SelectionCache.UUID = @UUID
                AND SelectionCache.TableCode = @TableCode -- this is the code for File table  
                AND     [File].Id <> 0 
                AND     [File].FileTypeId = FileType2Lexicon.FileTypeId 
                AND     FileType2Lexicon.LexiconId = @LexiconId
                AND     [File].ClientIdString = [People].ClientIdString
                AND     CFV.Value <> ''
                AND     CF2L.Label = 'Date of Arrest'

This ends up returning:

Id  ShortFileNameMatterName Summary             FileTypeLabelDefaultPhone   DOA         CustomRecordsetId
4691    Bob State v.  Bob   RETAINED:1/1/2013   Criminal    (123) 242-8454  2013-01-16  6942
4691    Bob State v.  Bob   RETAINED:1/1/2013   Criminal    (123) 242-8454  2013-01-16  6948

As apparent, the rows are duplicating because of the recordsetId column. Each table row does have it's own UUID as well.

Any ideas? I've been working on this for days.

EDIT: Here is my solution that I found.

    WITH RankedCTE AS(
        SELECT ROW_NUMBER() OVER(PARTITION BY [File].Id ORDER BY CustomRecordsetId DESC) AS RowNumber, [File].*, FileType2Lexicon.Label as FileTypeLabel, [People].DefaultPhone, [People].InvertedName, CFV.Value as DOA
            FROM FileType2Lexicon, SelectionCache, [People], [File]
            INNER JOIN [CustomRecordSet]
            ON [CustomRecordset].RecordId = [File].Id
            INNER JOIN (SELECT Value, CustomFieldId, CustomRecordsetId FROM [CustomFieldValue]) CFV
            ON  [CustomRecordset].Id = CFV.CustomRecordsetId
            INNER JOIN (SELECT CustomFieldId, Label FROM [CustomField2Lexicon]) CF2L
            ON CF2L.CustomFieldId = CFV.CustomFieldId
            WHERE   [File].Id = SelectionCache.RecordId
            AND SelectionCache.UUID = @UUID
            AND SelectionCache.TableCode = @TableCode -- this is the code for File table  
            AND     [File].Id <> 0 
            AND     [File].FileTypeId = FileType2Lexicon.FileTypeId 
            AND     FileType2Lexicon.LexiconId = @LexiconId
            AND     [File].ClientIdString = [People].ClientIdString
            AND     CFV.Value <> ''
            AND     (CF2L.Label = 'Date of Arrest')
        SELECT *
        FROM RankedCTE
        WHERE RowNumber = 1

你有没有考虑过使用任何一个……</p> 

SELECT DISTINCT [FILE].*, (etc)

甚至是……</p> 

GROUP BY [FILE].id

如果问题是RecordSetId，则按其余列分组并为该列使用聚合列。或者，通过聚合记录集来解决问题：

   SELECT [File].*, FileType2Lexicon.Label as FileTypeLabel, [People].DefaultPhone, CFV.Value as DOA, CFV.CustomRecordsetId
        FROM FileType2Lexicon, SelectionCache, [People], [File]
        INNER JOIN (select RecordId, max(id) as id
                    from [CustomRecordSet]
                    group by recordId
                   ) CustomRecordSet
        ON [CustomRecordset].RecordId = [File].Id
        INNER JOIN (SELECT Value, CustomFieldId, CustomRecordsetId FROM [CustomFieldValue]) CFV
        ON  [CustomRecordset].Id = CFV.CustomRecordsetId
        INNER JOIN (SELECT CustomFieldId, Label FROM [CustomField2Lexicon]) CF2L
        ON CF2L.CustomFieldId = CFV.CustomFieldId
        WHERE   [File].Id = SelectionCache.RecordId
        AND SelectionCache.UUID = @UUID
        AND SelectionCache.TableCode = @TableCode -- this is the code for File table  
        AND     [File].Id <> 0 
        AND     [File].FileTypeId = FileType2Lexicon.FileTypeId 
        AND     FileType2Lexicon.LexiconId = @LexiconId
        AND     [File].ClientIdString = [People].ClientIdString
        AND     CFV.Value <> ''
        AND     CF2L.Label = 'Date of Arrest'

这个版本任意选择最大id。
