值的總和，並在今年的格式顯示

Question

SELECT datesold, SUM(salesprice) FROM Cust.trans Group By datesold;

我得到這個：

DateSold Sum(SalesPrice) 
12/12/08 800 
18/12/08 200 
18/11/11 475 
28/06/09 17500 
16/03/09 450 
07/06/08 2750 
15/08/09 575 
19/12/07 500 
26/04/10 6500 
27/09/10 5450 
14/12/07 42500 
28/09/09 400 
27/09/09 400 
29/09/09 68750 
18/12/09 72500 
28/09/12 350 
18/01/08 400 
28/11/08 27500 
22/12/08 400 

我如何改變它每一年的總結salesprice的？

這應該這樣做。

SELECT YEAR(datesold), SUM(salesprice) FROM Cust.trans Group By YEAR(datesold);
