正如您的问题评论中提到的，拥有一个包含这么多列的表不是一个好主意。处理属性过滤的这种必要性的最佳方法是使用一个具有多对一关系Map的单独的值表。然后可以按如下方式筛选所需的值：

SELECT * FROM table a where conditional = X 
AND a.PrimaryId IN 
(SELECT P_Id FROM values WHERE ValueType = "value1" AND ValueValue = "x" AND P_Id = a.PrimaryId)
AND a.PrimaryId IN 
(SELECT P_Id FROM values WHERE ValueType = "value2" AND ValueValue = "y" AND P_Id = a.PrimaryId)
.... ;

也可以改用内部联接

SELECT * from table a where conditional = X
INNER JOIN values b
INNER JOIN values c
WHERE a.P_Id = b.P_Id AND a.P_Id = c.P_Id ...
AND b.ValueType = "value1" AND b.ValueValue = "x"
AND c.ValueType = "value2" AND c.ValueValue = "y"
... ;

尽管这比一个有数百列的表要好，但随着“值”数量的增加，这仍然会变得相当难看。我会考虑使用外部自由文本/属性搜索引擎或索引器。
