Question

我正在尝试将文本存储到表中，如下所示：

let insert_query = "insert into Messages(mid, mdate, sender, mtype, reply_to, is_forwarded, mtext, size, resolution, duration, emoji)"
insert_query += `values ('${message_id}', to_timestamp('${message_date}', 'DD.MM.YYYY HH24:MI:SS'), '${from_name}', '${media_type}', '${reply_to}', ${is_forwarded}, '${text}', '${media_size}', '${photo_resolution}', '${media_duration}', '${sticker_emoji}');`

这是一个相当长的查询，需要注意的重要部分是我在'${text}'字段中添加mtext的地方。

我收到此错误：

{ error: syntax error at or near "s"

  dataType: undefined,

  file: 'scan.l',
  line: '1134',
  routine: 'scanner_yyerror' }

我打印出insert_query表示何时发生这些错误，下面是一些结果：

insert into Messages(mid, mdate, sender, mtype, reply_to, is_forwarded, mtext, size, resolution, duration, emoji)
values ('message8224', to_timestamp('21.06.2019 21:27:34', 'DD.MM.YYYY HH24:MI:SS'), 'AmirAShabani', 'text', '', false, 'he's a loser', '', '', '', '');

我可以看到问题出在单引号字符上。我试图用\'替换它，就像这样：

text = child['children'][0]['data'].trim().replace('\'', '\\\'')

但这也无济于事，而且我不确定我是否应该这样做。

我该如何解决？
