【问题描述】：

我正在使用 npm 模块 mysql2
这里是代码：

var values = [['a', 'b', 'c', 'd', 'https://ne.wikipedia.org/wiki/%E0%A4%AE%E0%A5%81%E0%A4%96%E0%A5%8D%E0%A4%AF_%E0']];
    con.query(
      "INSERT INTO urlparse (title, description, author, keywords, url) VALUES ?",
      [values],
      function(err, result) { 
        if (err) throw err;
      }
    );
  });

这是我得到的错误：

                 ^

请帮忙。

【问题讨论】：

您确定您的驱动程序支持将? 扩展为多个值吗？您可能需要为每列添加一个?。
您正在为查询中的值传递一个数组数组，请尝试使用values 而不是[values]

【解决方案1】：

您正在为查询中的值传递一个数组数组尝试使用values 而不是[values]

var values = ['a', 'b', 'c', 'd',
'https://ne.wikipedia.org/wiki/%E0%A4%AE%E0%A5%81%E0%A4%96%E0%A5%8D%E0%A4%AF_%E0'];

con.query(
 "INSERT INTO urlparse (title, description, author, keywords, url) VALUES (?, ?, ?, ?, ?)",
 values, // Array of values here
 function(err, result) { 
   if (err) throw err;
 }
);
