SQL Query创建日期和金额的记录？

Question

我有一张看起来像这样的表：

------------------------------------
|  ID  | Amount | Date             |
------------------------------------
|  1   | 50.00  | 10/02/2010       |
|  2   | 20.00  | 10/02/2010       |
|  3   | 30.00  | 12/02/2010       |
|  4   | 70.00  | 12/02/2010       |
|  5   | 40.00  | 12/02/2010       |
------------------------------------

现在的问题是，如何创建一个查询，将按日期汇总金额并将其分组：

10/02/2010 70.00
12/02/2010 140.00

Answer 1

SELECT [Date], SUM(Amount) TotalAmount
FROM YourTable
GROUP BY [Date]
