如果按以下方式去获取特定条件下（hours=14）随机行会返回错误的数据，返回行的id字段和其他字段不是同一行的数据，而在数据库直接执行该语句则正常
$Model->query('
SELECT *
FROM `table` AS t1
JOIN (SELECT ROUND(RAND() * ((SELECT MAX(id) FROM `table`)-(SELECT MIN(id) FROM `table`))+(SELECT MIN(id) FROM `table`)) AS id) AS t2
WHERE t1.id >= t2.id and hours =14
ORDER BY t1.id LIMIT 1');
如果不加条件就正常
