SQL查询中的语法错误。无法找到错误

Question

我在mysql中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是一个表格，num，place和person是列表中单个项目的值。我也在红宝石脚本中使用它。

我收到语法错误。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`’

我无法弄清楚这个问题。请帮帮我。

Answer 1

查看查询的ORDER BY部分

ORDER BY list.person, list.state='closed' DESC, list.updated_at DESC 

list.state不应该有=＆＃39;已关闭＆＃39;

只需尝试将其全部更改为

ORDER BY list.person, list.state DESC, list.updated_at DESC

Answer 2

我认为你在双引号中使用了错误的字符。你有“。请改为"。
