如何在SQL中按最大行数排序

Question

I have this stored procedure and I want to sort by number of total result returns. Means customer with maximum orders must come first and so on Following is my stored procedure.

BEGIN
  SELECT    Customer.Customer_Name, Item.Item_Name, 
       Count(Item.Item_Name)  , Customer_Sale.Quantity_Customer,
       Customer_Sale.Sale_Price ,Customer_Sale.Total_Price,  
       Customer_Sale.Date ,Total_Remaining_Previous, Today_Credit, 
       Total_Remaining_Now  , Today_Receiving , Total_Xhot
FROM         Customer  JOIN
                         Customer_Sale ON Customer.Customer_Id = Customer_Sale.Customer_Id INNER JOIN
                         Customer_Account on Customer.Customer_Id=Customer_Account.Customer_Id inner join 
                         Unit ON Customer_Sale.Unit_Id = Unit.Unit_Id INNER JOIN
                         Item ON Customer_Sale.Item_Id = Item.Item_Id 

                         WHERE  Customer_Sale.Date = @date and Customer_Account.Customer_Date=@date 
                          group by Item.Item_Name

END

Answer 1

您可以将查询括在括号中并执行SELECT * FROM () ORDER BY ORDER_COLUMN_NAME吗？

Answer 2

I am Assuming that the “Count(Item.Item_Name)” is your attempt at this. You have to use the Over clause like this:

SELECT
Customer.Customer_Name
,Item.Item_Name
,Count(Item.ID) OVER (PARTITION BY Customer.Customer_Name) AS ItemCount
,Customer_Sale.Quantity_Customer
,Customer_Sale.Sale_Price
,Customer_Sale.Total_Price
,Customer_Sale.Date
,Total_Remaining_Previous
,Today_Credit
,Total_Remaining_Now
,Today_Receiving
,Total_Xhot

FROM Customer INNER JOIN Customer_Sale ON Customer.Customer_Id = Customer_Sale.Customer_Id INNER JOIN Customer_Account ON Customer.Customer_Id = Customer_Account.Customer_Id INNER JOIN Unit ON Customer_Sale.Unit_Id = Unit.Unit_Id INNER JOIN Item ON Customer_Sale.Item_Id = Item.Item_Id WHERE Customer_Sale.Date = @date AND Customer_Account.Customer_Date = @date

Can you try

BEGIN
        SELECT   Customer.Customer_Name ,
                 Item.Item_Name ,
                 COUNT(Item.Item_Name) ,
                 Customer_Sale.Quantity_Customer ,
                 Customer_Sale.Sale_Price ,
                 Customer_Sale.Total_Price ,
                 Customer_Sale.Date ,
                 Total_Remaining_Previous ,
                 Today_Credit ,
                 Total_Remaining_Now ,
                 Today_Receiving ,
                 Total_Xhot
        FROM     Customer
                 JOIN Customer_Sale ON Customer.Customer_Id = Customer_Sale.Customer_Id
                 INNER JOIN Customer_Account ON Customer.Customer_Id = Customer_Account.Customer_Id
                 INNER JOIN Unit ON Customer_Sale.Unit_Id = Unit.Unit_Id
                 INNER JOIN Item ON Customer_Sale.Item_Id = Item.Item_Id
        WHERE    Customer_Sale.Date = @date
                 AND Customer_Account.Customer_Date = @date
        GROUP BY Item.Item_Name;
        ORDER BY COUNT(1) OVER (PARTITION BY Customer.Customer_Name) DESC
    END;
