nodejs mysql插入问题 [英] nodejs mysql insert issue

问题描述

exports.adduser = function(connection) {
    return function(req, res) {

        // get form values
        var username = req.body.username;
        var firstname = req.body.firstname;
        var lastname = req.body.lastname;

        var post = {
            username : username,
            firstname : firstname,
            lastname : lastname
        };

        connection.query('INSERT INTO myDatabase VALUES ?', post, function(err, result) {
            if (err) {
                res.send("There was a problem adding the information to the database.");
            }
        });
    }
}

这似乎不起作用.有人看到任何明显的问题吗?语法正确吗?当我按下表单上的提交"按钮时，它只是挂起，并且插入从未发生.我已经确认表格获得正确的值.数据库表中的字段是用户名，名字和姓氏.

This doesn't seem to work. Does anyone see any glaring issues? Is the syntax correct? When I press the submit button on my form, it just hangs, and the insert never occurs. I have confirmed that the form gets the right values. The fields in the database table are username, firstname, and lastname.

推荐答案

您误读了本手册！如果您正在使用INSERT INTO的对象，则需要使用SET:

You misread the manual! If you are using an object to INSERT INTO you need to use SET:

INSERT INTO myDatabase SET ?

引用:

如果您注意了，您可能已经注意到，这种转义可以使您执行以下整洁的事情:

If you paid attention, you may have noticed that this escaping allows you to do neat things like this:

var post  = {id: 1, title: 'Hello MySQL'};
var query = connection.query('INSERT INTO posts SET ?', post, function(err, result) {
  // Neat!
});
console.log(query.sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'
