经过几个小时的合并和尝试，我终于做到了：
SELECT * FROM objects as o
/* filter1 join */
INNER JOIN
attributes AS f1
ON
o.object_id = f1.attr_object_id
AND
f1.attr_property_id = 1
AND
f1.attr_value <= '100000'
/* filter2 join */
INNER JOIN
attributes AS f2
ON
f1.attr_object_id = f2.attr_object_id
AND
f2.attr_property_id = 2
AND
f2.attr_value > '2000'
WHERE
o.object_group_id = 1
我太接近了，因此将所有过滤条件都移至INNER JOIN。
