将值传递给嵌套的子查询显示不同的行

Question

我在使用sql时遇到更多问题，每天都有其他毕业生获得一张纸，他们必须解决如何解决10个查询问题。

我可以在硬编码值时获取下面的代码来返回数据，但我需要做的是将name和item的值传递给子查询，我不能使用函数或视图并显示每个客户的结果。< / p>

SELECT  
    c.Name AS 'A',
    c.Address AS 'B',
    sales2.MinPrice AS 'C',
    MAX(sales.TotalItemsSold) AS 'D'
FROM 
    ABC c, 
    (SELECT SUM(i.Qty) AS TotalItemsSold
     FROM DEF i
     INNER JOIN GHI o ON i.Orderno = o.OrderNo               
     WHERE o.Cust = 'name') sales, 
    (SELECT (Min(s.Price) * i.Qty) AS MinPrice
     FROM ABC c 
     INNER JOIN GHI o ON c.Name = o.Cust        
     INNER JOIN DEF i ON i.Orderno = o.OrderNo  
     INNER JOIN JKL s ON i.Item = s.Item
     WHERE i.Item = 'item' AND o.Cust = 'name'
     GROUP BY i.Qty) sales2
GROUP BY 
    c.Name, c.Address, Sales2.MinPrice
