 GROUP BY t2.ItemID ORDER BY Quantity desc");

Answer 1

您缺少外部 SELECT 语句中的 FROM 部分（第 2 行）

你在那里有一个 WHERE 条件

另外我认为您不需要为此进行子查询

试试这个

('  SELECT TOP 5 t2.ItemID, SUM(t2.Quantity)  as Quantity 
    FROM Orders as t1 
        INNER JOIN BasketItems as t2 on t2.BasketID = t1.BasketID
    WHERE t1.OrderStatusID = 3 
    AND t1.OrderDate BETWEEN '" + LastWeekDate + "' AND '" + TomorrowsdaysDate + "'
    GROUP BY t2.ItemID ORDER BY 2 desc
 ');
