从这里改编：
SELECt T2.id, T2.nameFROM ( SELECt @r AS _id, (SELECT @r := parent_id FROM table1 WHERe id = _id) AS parent_id, @l := @l + 1 AS lvl FROM (SELECT @r := 5, @l := 0) vars, table1 h WHERe @r <> 0) T1JOIN table1 T2ON T1._id = T2.idORDER BY T1.lvl DESC
该行
@r := 5是当前页面的页码。结果如下：
1, 'Home'2, 'about'4, 'Legal'5, 'Privacy'
