Question

我有一个与Heroku一起部署的Node.JS应用程序，它具有简单的CRUD系统。但是，每当我使用Web应用程序本身更新行时，我都会遇到问题。

这是我的server.js文件中的UPDATE语句的代码

app.post('/logs/edit/:mobile', function(req, res){
   var input = JSON.parse(JSON.stringify(req.body));
   var mobile = req.params.mobile;
   var data = {            
        last    : input.last,
        first   : input.first,
        middle  : input.middle,
        mobile  : input.mobile,
        email   : input.email,
        bday    : input.bday,
        status  : input.status
   };
   connection.query("UPDATE logs set ? WHERE mobile = ? ",[data,mobile], function(err, rows){  
      if(err) console.log(err);
      res.redirect('/logs');          
   });
});

然后这是我的日志中显示的错误

我希望有一个解决方案。

非常感谢

据我所知，如果你向他们发送像你一样使用data的JSON，那么MySQL版本将不会起作用。我实际上并不知道您的代码有什么问题，但是，我看到您的节点代码没问题。

我建议您直接在mysql上尝试该查询（使用控制台或工作台）
