SQL 服务器- Select 进入另一个 Select 出错

Question

我创建查询以在我的数据库中获取我的商品，如下所示

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;

本次查询得到的商品有他们existnumber有颜色属性的商品，现在当我运行这个查询时我得到这个错误：

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.

这个错误是因为在某些商品中有两个 Color 而我想为这个商品得到两行

请检查此查询

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;
