Question

我在使用CTE对存储过程进行排序时遇到问题。如果我不使用case语句，那么排序有效，但我需要能够对四列中的任何一列进行排序。

任何帮助都将非常感激。以下是有问题的存储过程的片段....

DECLARE @ValuationIds ValuationIdTableType

    ;WITH CTE
    AS
    (
        SELECT V.[Id], Registration, (ROW_NUMBER() OVER
        (
            ORDER BY  
                CASE WHEN @SortCol='Registration' and @Direction='DESC' then Registration END DESC,
                CASE WHEN @SortCol='Registration' and @Direction='ASC' then Registration END ASC
        )) AS seq 
        FROM [Valuation] V WITH (NOLOCK)
          INNER JOIN dbo.Vehicle a ON a.Id = V.VehicleId
          INNER JOIN dbo.Derivative b on b.Id = a.DerivativeId
          INNER JOIN dbo.Model c on c.Id = b.ModelId
          INNER JOIN dbo.ModelRange d on d.Id = c.ModelRangeId
          INNER JOIN dbo.Manufacturer e on e.Id = d.ManufacturerId
          LEFT JOIN dbo.Disposal f ON f.ValuationId = V.Id            
            CROSS APPLY (
                SELECT TOP 1 *
                FROM dbo.SellerAdvanceValuation savCA
                INNER JOIN udf_SplitIDs(@CentreIdList) IdList 
                ON IdList.EntityID = savCA.CentreId 
                WHERE V.Id = savCA.ValuationId
                ORDER BY Id DESC
            ) sav 
        WHERE [Deleted] = 0
          AND f.Id IS NULL
          AND COALESCE(@Registration, [Registration]) = [Registration]
          AND COALESCE(@VehicleStatusId,[VehicleStatusId] ) = [VehicleStatusId] 
          AND COALESCE(@StartDate,sav.RequestDateTime ) <= sav.RequestDateTime 
          AND sav.RequestDateTime <= COALESCE(@EndDate,sav.RequestDateTime ) 
          AND sav.Amount IS NOT NULL
          AND sav.ValuationDateTime IS NOT NULL
          AND sav.ValuationDateTime > @ValuationExpiryDateTime
    )
    INSERT INTO @ValuationIds(ValuationId)
    SELECT a.Id
    FROM CTE a
    WHERE seq BETWEEN @StartIndex AND (@StartIndex + @MaxRows - 1)

    EXEC dbo.Valuation_Get_All @ValuationIds

更新：如果我做了以下它可以工作，但我真的不想这样做。我有4列，必须在每列上升和下降。

DECLARE @ValuationIds ValuationIdTableType

    ;WITH CTE
    AS
    (
        SELECT V.[Id], Registration, (ROW_NUMBER() OVER
        (
            ORDER BY  Registration DESC
                --CASE WHEN @SortCol='Registration' and @Direction='DESC' then Registration END DESC,
                --CASE WHEN @SortCol='Registration' and @Direction='ASC' then Registration END ASC
        )) AS seq 
        FROM [Valuation] V WITH (NOLOCK)
          INNER JOIN dbo.Vehicle a ON a.Id = V.VehicleId
          INNER JOIN dbo.Derivative b on b.Id = a.DerivativeId
          INNER JOIN dbo.Model c on c.Id = b.ModelId
          INNER JOIN dbo.ModelRange d on d.Id = c.ModelRangeId
          INNER JOIN dbo.Manufacturer e on e.Id = d.ManufacturerId
          LEFT JOIN dbo.Disposal f ON f.ValuationId = V.Id            
            CROSS APPLY (
                SELECT TOP 1 *
                FROM dbo.SellerAdvanceValuation savCA
                INNER JOIN udf_SplitIDs(@CentreIdList) IdList 
                ON IdList.EntityID = savCA.CentreId 
                WHERE V.Id = savCA.ValuationId
                ORDER BY Id DESC
            ) sav 
        WHERE [Deleted] = 0
          AND f.Id IS NULL
          AND COALESCE(@Registration, [Registration]) = [Registration]
          AND COALESCE(@VehicleStatusId,[VehicleStatusId] ) = [VehicleStatusId] 
          AND COALESCE(@StartDate,sav.RequestDateTime ) <= sav.RequestDateTime 
          AND sav.RequestDateTime <= COALESCE(@EndDate,sav.RequestDateTime ) 
          AND sav.Amount IS NOT NULL
          AND sav.ValuationDateTime IS NOT NULL
          AND sav.ValuationDateTime > @ValuationExpiryDateTime
    )
    INSERT INTO @ValuationIds(ValuationId)
    SELECT a.Id
    FROM CTE a
    WHERE seq BETWEEN @StartIndex AND (@StartIndex + @MaxRows - 1)

    EXEC dbo.Valuation_Get_All @ValuationIds

Answer 1

INSERT INTO @ValuationIds（ValuationId）选择a.Id 来自CTE a 在哪里@WartIndex与（@StartIndex + @MaxRows - 1）之间的关系 ORDER BY { ColumnFromInCTE }

????

CTE没有排序
