存儲過程得到分頁排序的結果與計算的數據列

Question

我想做一個存儲過程得到分頁排序結果，但這裏是扭曲。我必須添加一列並填充計算/計算的數據。目前，我有

ALTER proc [dbo].[pr_GetPagedSortedOrdersByUser]  
(
@userid numeric(18,0),    
@CurrentPage int,    
@PageSize int,    
@SortField varchar(200),    
@SortOrder varchar(5),   
@status varchar(50)   
)    
as    
begin    
with temp as    
    (    
    select * 
    ,ROW_NUMBER() OVER (order by    
     CASE WHEN @SortField = 'orderdate' AND @SortOrder = 'Desc' THEN orderdate END DESC,    
     CASE WHEN @SortField = 'orderdate' THEN orderdate END,  
     CASE WHEN @SortField = 'netamount' AND @SortOrder = 'Desc' THEN netamount END DESC,    
     CASE WHEN @SortField = 'netamount' THEN netamount END,  
     CASE WHEN @SortField = 'id' AND @SortOrder = 'Desc' THEN id END DESC,    
     CASE WHEN @SortField = 'id' THEN id END      
     ) AS ROWID    
    from tbOrder  
    where (@status='All' or delivered=@status)and userid=@userid 

)    
    select * , 
    (
    netamount - discount 
) as 'Gross'  
    from temp    
    where rowid>((@CurrentPage - 1) * @PageSize) and rowid <(@CurrentPage * @PageSize + 1)    

    select count(*) as [count]    
    from tbOrder  
    where (delivered=@status or @status='All')and userid=@userid  
end 

注：Gross列不存在於數據庫中，我應該能值Gross傳遞給@SortField

你應該只能夠將您的計算列添加到您的case語句排序：

select * 
    ,ROW_NUMBER() OVER (order by    
     CASE WHEN @SortField = 'orderdate' AND @SortOrder = 'Desc' THEN orderdate END DESC,    
     CASE WHEN @SortField = 'orderdate' THEN orderdate END,  
     CASE WHEN @SortField = 'netamount' AND @SortOrder = 'Desc' THEN netamount END DESC,    
     CASE WHEN @SortField = 'netamount' THEN netamount END,  
     CASE WHEN @SortField = 'id' AND @SortOrder = 'Desc' THEN id END DESC,    
     CASE WHEN @SortField = 'id' THEN id END, 
     CASE WHEN @SortField = 'gross' AND @SortOrder = 'Desc' THEN netamount - discount END DESC,    
     CASE WHEN @SortField = 'gross' THEN netamount - discount END 
     ) AS ROWID    
    from tbOrder
