不是在WHERE子句

Question

內的IIF內的條款，我希望做這樣的事情：

CREATE FUNCTION [Aftermarket].[ft_Filter_V41_HubAssembly_AxleStudThreads_DEV] (
    @SearchTokens     dbo.SearchTokenTableType  READONLY, 
    @AftermarketHubAssemblyNumbers dbo.ConMetPartNumberTableType READONLY, 
    @TruckCompartmentIds    dbo.IntegerTableType   READONLY, 
    @TruckMakeIds     dbo.IntegerTableType   READONLY, 
    @AxleNameIds      dbo.IntegerTableType   READONLY, 
    @GrossAxleWeightRatingRangeIds dbo.IntegerTableType   READONLY, 
    @AxleStudThreadIds    dbo.IntegerTableType   READONLY, 
    @WheelMaterialStudLengthClassIds dbo.IntegerTableType   READONLY, 
    @HubCastingMaterialTypeIds  dbo.IntegerTableType   READONLY, 
    @HubAssemblyTypeIds    dbo.IntegerTableType   READONLY, 
    @ExcludeProvidedValues BIT = 1 
) 
RETURNS TABLE 
RETURN 
    SELECT DISTINCT v.AxleStudThreadId AS Id, 
    CASE v.AxleStudThreadId WHEN 0 THEN N'—' ELSE th.ThreadDesignation END AS Designation, 
    bt.DiameterValue AS DiameterInch, 
    CASE v.AxleStudThreadId WHEN 0 THEN N'—' 
          WHEN 6 THEN N'3/4' 
          WHEN 8 THEN N'5/8' 
          ELSE th.ThreadDesignation 
          END AS NominalDiameter 
    FROM Aftermarket.vFilters_V3_HubAssemblies AS v 
    JOIN Stud.Threads AS th ON v.AxleStudThreadId = th.Id 
    JOIN Stud.BaseThreads AS bt ON th.BaseThreadId = bt.Id 
    WHERE (((SELECT COUNT(PartNumber) FROM @AftermarketHubAssemblyNumbers) = 0) OR v.HubAssemblyNumber     IN (SELECT PartNumber FROM @AftermarketHubAssemblyNumbers)) 
     AND (((SELECT COUNT(Value)  FROM @TruckCompartmentIds)    = 0) OR v.TruckCompartmentId     IN (SELECT Value FROM @TruckCompartmentIds    )) 
     AND (((SELECT COUNT(Value)  FROM @TruckMakeIds)     = 0) OR v.TruckMakeId      IN (SELECT Value FROM @TruckMakeIds      )) 
     AND (((SELECT COUNT(Value)  FROM @AxleNameIds)      = 0) OR v.AxleNameId       IN (SELECT Value FROM @AxleNameIds      )) 
     AND (((SELECT COUNT(Value)  FROM @GrossAxleWeightRatingRangeIds) = 0) OR v.GawrRangeId      IN (SELECT Value FROM @GrossAxleWeightRatingRangeIds  )) 

     AND (((SELECT COUNT(Value) FROM @AxleStudThreadIds) = 0) OR IIF(@ExcludeProvidedValues = 1, 
                      v.AxleStudThreadId NOT IN (SELECT Value FROM @AxleStudThreadIds), 
                      v.AxleStudThreadId IN (SELECT Value FROM @AxleStudThreadIds)) 
                    ) 

     AND (((SELECT COUNT(Value)  FROM @WheelMaterialStudLengthClassIds) = 0) OR v.WheelMaterialStudLengthClassId  IN (SELECT Value FROM @WheelMaterialStudLengthClassIds )) 
     AND (((SELECT COUNT(Value)  FROM @HubCastingMaterialTypeIds)  = 0) OR v.HubCastingMaterialTypeId   IN (SELECT Value FROM @HubCastingMaterialTypeIds   )) 
     AND (((SELECT COUNT(Value)  FROM @HubAssemblyTypeIds)    = 0) OR v.HubAssemblyTypeId     IN (SELECT Value FROM @HubAssemblyTypeIds    )) 
     AND ((SELECT COUNT(Token) 
      FROM @SearchTokens 
      WHERE ((LEN(Token) > 0) AND ((CAST(CHARINDEX(Token, th.ThreadDesignation) AS INT) > 0)))) = (SELECT COUNT(Token) FROM @SearchTokens WHERE LEN(Token) > 0)) 

這是無效的T-SQL語法。我怎麼能表達WHERE ... IIF（cond，Field NOT IN ...）想法達到同樣的效果？

IIF(@ExcludeProvidedValues = 1, 
     v.AxleStudThreadId NOT IN (SELECT Value FROM @AxleStudThreadIds), 
     v.AxleStudThreadId IN (SELECT Value FROM @AxleStudThreadIds)) 
    ) 

Answer 1

替換：

OR IIF(@ExcludeProvidedValues=1, v.AxleStudThreadId NOT IN (SELECT Value FROM @AxleStudThreadIds), 1) 

有了：

1 = Case when @ExcludeProvidedValues=1 and v.AxleStudThreadId NOT IN (SELECT Value FROM @AxleStudThreadIds) then 1 else 0 end 

Answer 2

以下條款的伎倆

AND (
     ((SELECT COUNT(Value) FROM @AxleStudThreadIds) = 0) 
    OR ((@ExcludeProvidedValues = 0) AND v.AxleStudThreadId IN (SELECT Value FROM @AxleStudThreadIds)) 
    OR ((@ExcludeProvidedValues = 1) AND v.AxleStudThreadId NOT IN (SELECT Value FROM @AxleStudThreadIds)) 
) 

下面是完整的完整UDF定義：
