如图，
满足条件 propId = 2 且 valueId =4 还需满足 propId = 3 且 valueId =8 的itemId
这时只有item =4满足
item为6 不满足 以为只有 propId = 3 且 valueId =8

引用 1 楼 mafeifan 的回复:

select *
  from t t2
 where t2.itemid in (select itemid
                       from t t1
                      where t1.propid = 2
                        and valueid = 4)
   and t2.propid = 3
   and t2.valueid = 8
