搜索在存儲過程中無法正常工作

Question

我創建了一個用分頁進行搜索的存儲過程，但搜索無法正常工作。你能告訴我在這個存儲過程中我做錯了什麼嗎？

ALTER PRocedure [dbo].[uspGetAddressByClientAndCode]   
    @PageIndex INT = 1,   
    @PageSize INT = 10,   
    @ClientId int,   
    @clientName varchar(40)= null,   
    @Code varchar(2)=null,   
    @RecordCount INT OUTPUT   
AS   
BEGIN   
    SET NOCOUNT ON;   

    SELECT * FROM (  
     SELECT ROW_NUMBER() OVER (ORDER BY AD.[CLIENTID] DESC) AS RowNumber 
     ,AD.[NAME]   
     ,AD.[ADDR]   
     ,AD.[CITY]   
     ,AD.[STPROV]   
     ,AD.[ZIPPOSTAL]   
     ,AD.[COUNTRY]   
     ,AD.[ZONE]   
     ,AD.[CLIENTID]   
     ,CL.BCLIENT   
     ,AD.ADDRESSID   
    FROM 
     [Address] Ad   
    INNER JOIN 
     client CL ON CL.CLIENTID = AD.[CLIENTID]   
    WHERE    
     AD.CLIENTID = @ClientId   
     AND (AD.NAME IS NULL OR AD.NAME Like @clientName +'%')   
     AND (AD.code IS NULL OR AD.code = @Code) 
) As PageTable   
WHERE 
    RowNumber BETWEEN (@PageIndex -1) * @PageSize + 1 AND (((@PageIndex -1) * @PageSize + 1) + @PageSize) - 1   
END

即使目前還不清楚爲什麼這個存儲過程都不能正常工作我想你必須改變WHERE子句這樣的：

WHERE    
     AD.CLIENTID = @ClientId   
     AND (@clientName IS NULL OR AD.NAME Like @clientName +'%')   
     AND (@Code IS NULL OR AD.code = @Code)
