GROUP BY或Aggregation Function错误消息

Question

SQL新手。

我尝试使用SQL语句检索数据库中产品记录的数据。

但是，我收到一条错误

  

Msg 8120，Level 16，State 1，Line 11   专栏＆＃39; AggregatedSalesHistory.PriceZoneID＆＃39;在选择列表中无效，因为它不包含在聚合函数或GROUP BY子句中。＆＃34;

我正在使用Microsoft SQL Server Management Studio 2014，这是我运行的声明 -

select  
    PriceZoneID,
    Date, 
    CAST(ash.Date as date) as Date, 
    SUM(ash.Sales) as Units, 
    SUM(ash.Sales * ash.Price) AS CashSales
from AggregatedSalesHistory AS ASH 
    INNER JOIN ForecastProductScenario AS LRF
                ON ash.ProductSID = lrf.ProductSID AND ash.date = lrf.ForecastDate AND ash.PriceZoneID = lrf.ZoneID AND ash.SegmentID = lrf.SegmentID 
                WHERE ash.PriceZoneID = 2 
                AND ash.ProductSID = '56358E18-7B49-4346-8B70-DC5DE122DB59'
                AND DATE = 12/10/2014
