T-SQL表加一排，

Question

表填充爲不太重要的值的摘要如下

CustomerName     SalesValue 
CusA       100 
CusB       250 
CusC       900 
CusD       1200 
CusE       2500 

我想查詢其中將列出的銷售值，我所有的客戶，如果值（每客戶）超過1000如果是少的話，我只是想看到一個摘要行表明所有客戶的總價值< = 1000。結果會是這個樣子：提前

CusE       2500 
CusD       1200 

(Small Value Customers)  1250 

Total       4950 

感謝。

Answer 1

也許：

WITH sales AS 
(
    SELECT [CustomerName], [SalesValue], 
     CustSales = SUM(SalesValue)OVER(PARTITION BY CustomerName) 
    FROM dbo.Sales 
) 
SELECT CustomerName, CustSales FROM(
    SELECT 1 AS Source, 
     CustomerName, 
     CustSales = SUM(CustSales) FROM sales 
    GROUP BY CustomerName 
    HAVING SUM(CustSales) > 1000 

    UNION ALL 

    SELECT 2 As Source, 
     CustomerName = '(Small Value Customers)', 
     CustSales = SUM(CustSales) FROM sales 
    WHERE CustSales <= 1000 

    UNION ALL 

    SELECT 3 As Source, 
     CustomerName = 'Total', 
     CustSales = SUM(CustSales) FROM sales 
) AS X 
ORDER BY X.Source, X.CustSales DESC

Answer 2

你可以這樣做：

DECLARE @LargeCustomersSum INT 

    SELECT @LargeCustomersSum = SUM(SalesValue) 
    FROM YourTable 
    WHERE SalesValue >= 1000 

    DECLARE @SmallCustomersSum INT 

    SELECT @SmallCustomersSum = SUM(SalesValue) 
    FROM YourTable 
    WHERE SalesValue <= 1000 

    SELECT 'Large Value Customers', @LargeCustomersSum 
    UNION 
    SELECT CustomerName, SalesValue 
    FROM YourTable 
    ORDER BY SalesValue DESC 
    WHERE SalesValue >= 1000 

    UNION 
    SELECT 'Small Value Customers', @SmallCustomersSum 
    UNION 
    SELECT CustomerName, SalesValue 
    FROM YourTable 
    ORDER BY SalesValue DESC 
    WHERE SalesValue <= 1000 

    UNION 
    SELECT 'Total', @LargeCustomersSum + @SmallCustomersSum 

Answer 3

這裏是查詢

select SalesValue, CustomerName from cus_sales where SalesValue > 1000 
UNION 
    select sum(SalesValue) as Sum, 'Others' as CustomerName from cus_sales where SalesValue <= 1000 
UNION 
select sum(SalesValue) as Sum, 'Total' as CustomerName from cus_sales 

和sqlfiddle

Answer 4

選項爲SQLServer2008的+與GROUP BY ROLLUP

SELECT ISNULL(CASE WHEN SalesValue > 1000 THEN CustomerName 
        ELSE 'SmallValueCustomers' END, 'Total') AS CustomerName, 
     SUM(SalesValue) AS SumSalesValue 
FROM dbo.sales 
GROUP BY ROLLUP(CASE WHEN SalesValue > 1000 THEN CustomerName 
        ELSE 'SmallValueCustomers' END) 

演示上SQLFiddle

或者如果你不能用ROLLUP操作中使用GROUP BY子句

SELECT CASE WHEN SalesValue > 1000 THEN CustomerName 
      ELSE 'SmallValueCustomers' END AS CustomerName, 
     SUM(SalesValue) AS SumSalesValue 
FROM dbo.sales 
GROUP BY CASE WHEN SalesValue > 1000 THEN CustomerName 
       ELSE 'SmallValueCustomers' END 
UNION ALL 
SELECT 'Total', SUM(SalesValue) 
FROM dbo.sales
