我正在用mysql为我的数据库编写测试。

con.query(“SELECT  `list`.* FROM `list`  WHERE `list`.`place` = 86 AND `list`.`person` = \"#{person_id}\" AND (( (list.state = 'open' AND num=\"#{num}\") || (list.state = ?) )) AND (list.updated_at > \"2018-06-05\") ORDER BY list.person, list.state='closed' DESC, list.updated_at DESC LIMIT 50 OFFSET 1”)
``` `list` 是一张table `num` ,  `place` ，和 `person` 是列表中单个项的值。我还在ruby脚本中使用它。
我得到一个语法错误。错误消息是： `You have an error in your SQL syntax check the manual that corresponds to your MySQL server version for the right syntax to use near ‘`?) )) AND (list.update_at > “2018-06-05”)) ORDER BY list.person, or`’` 我搞不懂这个问题。请帮帮我。
