SQL服务器 - 选择在另外一个选择了错误

Question

创建查询来获取我的货在我的数据库如下图所示

SELECT 
    Goods.GoodsID ,Max(Price) 
    ExistNumber AS ExistNumber , 
    (SELECT p.ValueText 
    FROM STR.GoodsProperties gp 
    INNER JOIN PRP.Properties p ON p.PropertyID = gp.PropertyID 
    WHERE NodeText LIKE '/40/%' 
     AND gp.GoodsID = Goods.GoodsID) AS Color 
FROM  
    STR.Goods 
GROUP BY 
    Goods.GoodsID, ExistNumber; 

该查询拿到货与他们existnumber货物的颜色属性， 现在当我运行此查询我得到这个错误：

Msg 512, Level 16, State 1, Line 13
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

此错误是由于在某些货物造成有两个Color，我想获得两行此产品

请检查这个查询

SELECT Goods.GoodsID , 
     ExistNumber AS ExistNumber , 
     Prop.ValueText AS Color 
FROM STR.Goods 
     INNER JOIN (SELECT gp.GoodsID , 
          p.ValueText 
        FROM STR.GoodsProperties gp 
          INNER JOIN PRP.Properties p ON p.PropertyID = gp.PropertyID 
        WHERE NodeText LIKE '/40/%' 
        ) Prop ON Prop.GoodsID = Goods.GoodsID 
GROUP BY Goods.GoodsID , 
     ExistNumber , 
     Prop.ValueText;
