SQL Server 2012：窗口附近的'訂單'附近的語法不正確

Question

這應該是一個簡單的分區/排序依據...但是我今天有愚蠢的，並且看不到我惡意的方式。

這裏的架構和SQL：

create table #NoDiscountFleet 
(fleet_number int, 
customer_key int, 
posyear int, 
posmonth int, 
sale_net_val decimal(16,4), 
sale_tot_qty decimal(12,3), 
FirstDayOfMonth date, 
LastDayOfMonth date 
); 

select fleet_number, 
     lastdayofmonth, 
     tot_fleet_net_sales = sum(sale_net_val) over (partition by fleet_number order by fleet_number,lastdayofmonth) 
from #NoDiscountFleet 
group by fleet_number,lastdayofmonth 
     order by fleet_number; 

Answer 1

你不需要GROUP BY：

SELECT fleet_number, 
     lastdayofmonth, 
     tot_fleet_net_sales = SUM(sale_net_val) OVER (PARTITION BY fleet_number 
                 ORDER BY lastdayofmonth) 
FROM #NoDiscountFleet 
ORDER BY fleet_number;
