NodeJS不更新MySQL数据库

尝试使用Javascript和NodeJS在XAMPP本地主机上更新MySQL中的数据库表,但是由于某些原因,代码未按我认为的方式处理。这是一个时钟程序,我所要做的只是一个简单的测试,即单击按钮时将名称插入到列中。基本上,该部分代码到达时不执行任何操作(它仅在第一个按钮上)。我该怎么办?谢谢。

JS

var clock = {
    bool: false,
    in: 0,
    inText: "Clock-in time: ",
    inText2: "Already clocked in: ",
    out: 0,
    outText: "Not clocked in.",
    outText2: "Clock-out time is: "
};

var rest = {
    bool: false,
    out: 0,
    outText: "Break-out time is: ",
    outText2: "Already on break: ",
    in: 0,
    inText: "Not on break.",
    inText2: "Break-in time is: "

};

var mysql = require('mysql');

var con = mysql.createConnection({
    host: "localhost",
    user: "root",
    password: "",
    database: "mydb"

function clockIn(id) {

        case false:
            var d = new Date();
            var t = d.toLocaleTimeString();
            clock.bool = true;
            clock.in = t;
            document.getElementById(id).innerHTML = clock.inText + clock.in;
            con.connect(function (err) {
                if (err)
                    throw err;
                console.log("Connected!");
                var sql = "INSERT INTO timeclock (Name) VALUES ('Name')";
                con.query(sql, function (err, result) {

            document.getElementById(id).innerHTML = rest.inText2 + rest.in;
            break;
    }
}

var myVar = setInterval(myTimer, 1000);

function myTimer() {
    var d = new Date();
    var t = d.toLocaleTimeString();
    document.getElementById("time").innerHTML = "Current time is: " + t;
}

function resetBtnTxt(id, text) {
    setTimeout(function () {
        document.getElementById(id).innerHTML = text;
    }, 5000);
}
