Answer 1

另一种方式

WITH YourTable(LineNumber, UnitPrice, Quantity)
     AS (SELECT 1, 14,12
         UNION ALL
         SELECT 2, 09, 10
         UNION ALL
         SELECT 3, 34, 5
         UNION ALL
         SELECT 4, 18, 9
         UNION ALL
         SELECT 5, 42, 40
         UNION ALL
         SELECT 6, 07, 10
         UNION ALL
         SELECT 7, 45, 15)
SELECT LineNumber,
       UnitPrice,
       SUM(Quantity) AS Quantity
FROM   YourTable
GROUP  BY GROUPING SETS ( ( LineNumber, UnitPrice, Quantity ), ( ) ) 

Answer 2

要获得总数，您将使用聚合：

select sum(quantity) Total
from yourtable

要从表中返回数据：

select LineNumber, UnitPrice, Quantity
from yourTable

要将它们一起归还，您可以使用UNION ALL：

select LineNumber, UnitPrice, Quantity
from yourTable
UNION ALL
select 0, 0, sum(quantity) Total
from yourtable

-- For all the data from the table
SELECT [LineNumber], [UnitPrice], [Quantity] FROM [SomeTable]

-- For the sum of the quantity field.
SELECT SUM([Quantity]) AS [Sum] FROM [SomeTable]
