如何在查询中大写散列的 md5？

Question

在进入数据库之前如何将散列的 md5 大写？

我尝试了以下方法：

connection.query("UPDATE penguins SET password = UPPER(password)");

这有效，但它不会将刚注册的用户大写。它在数据库中每隔一个 md5 散列大写。

这是我的 INSERT 查询：

var insertQuery = "INSERT INTO penguins (moderator, registrationdate, inventory, email, password, username, nickname ) VALUES ('" + moderator + "','" + registrationdate + "','" + inventory + "','" + email +  "', + MD5('" + password + "'), '" + username + "', '"+username+"')";

这是我的整个护照攻略：

var moment = require('moment');
var datetime = moment().format('x')
var mysql = require('mysql');
var LocalStrategy = require('passport-local').Strategy;

var connection = mysql.createConnection({
    host: 'localhost',
    user: 'root',
    password: 'root'
});

connection.query('USE kitsune');

// expose this function to our app using module.exports
module.exports = function(passport) {

    // =========================================================================
    // passport session setup ==================================================
    // =========================================================================
    // required for persistent login sessions
    // passport needs ability to serialize and unserialize users out of session

    // used to serialize the user for the session
    passport.serializeUser(function(user, done) {
        done(null, user.id);
    });

    // used to deserialize the user
    passport.deserializeUser(function(id, done) {
        connection.query("SELECT * FROM penguins WHERE id = " + id, function(err, rows) {
            done(err, rows[0]);
        });
    });


    // =========================================================================
    // LOCAL SIGNUP ============================================================
    // =========================================================================
    // we are using named strategies since we have one for login and one for signup
    // by default, if there was no name, it would just be called 'local'

       passport.use('local-signup', new LocalStrategy({
        // by default, local strategy uses username and password, we will override with email
        usernameField: 'username',
        passwordField: 'password',
        gameusernameField: 'username',
        nicknameField: 'nickname',
        passReqToCallback: true // allows us to pass back the entire request to the callback
    },

    function(req, username, password, done) {

        // here you read from req
        const email = req.body.email
        const nickname = req.body.nickname
        const inventory = '%1'; // This is what the user gets on register. You can set this to anything that you want like: %1%2%3%4%5%6%7%8%9%10%11%12%13%14%15%16
        const moderator = '0';
        const registrationdate = datetime

    passport.serializeUser(function(username, done) {
        done(null, username);
    });

        // find a user whose email is the same as the forms email
        // we are checking to see if the user trying to login already exists
        connection.query("SELECT * FROM `penguins` WHERE `username` = '" + username + "'", function(err, rows) {
            console.log(rows);
            console.log("above row object");
            if (err) return done(err);
            if (rows.length) {
                return done(null, false, req.flash('signupMessage', 'That username is already taken.'));
            } else {

                // if there is no user with that email
                // create the user
                var newUserMysql = new Object();
                newUserMysql.registrationdate = registrationdate;
                newUserMysql.moderator = moderator;
                newUserMysql.inventory = inventory;
                newUserMysql.email = email;
                newUserMysql.password = password; // use the generateHash function in our user model
                newUserMysql.username = username;
                newUserMysql.nickname = nickname;
                var insertQuery = "INSERT INTO penguins (moderator, registrationdate, inventory, email, password, username, nickname ) VALUES ('" + moderator + "','" + registrationdate + "','" + inventory + "','" + email +  "', + MD5('" + password + "'), '" + username + "', '"+username+"')";
                console.log(insertQuery);
                console.log('Query is rolling!');
                connection.query(insertQuery, function(err, rows) {
                    newUserMysql.id = rows.insertId;
                    return done(null, newUserMysql);
                    });

            }

您是否在插入语句中尝试过 UPPER()，希望它能起作用。

    var insertQuery = "INSERT INTO penguins (moderator, registrationdate, inventory, email, password, username, nickname ) VALUES ('" + moderator + "',UNIX_TIMESTAMP(),'" + inventory + "','" + email +  "', + UPPER(MD5('" + password + "')), '" + username + "', '"+username+"')";
