Hi i am trying to build an odd display website for soccer matches

Im trying to get data from betfair which works fine then insert it to my database
Problem is that the function is only inserting the first item, what should i do?

const request = require('request');

const cheerio = require('cheerio');

const fs = require('fs');

const util = require('util');

const appendFile = util.promisify(fs.appendFile);

const async = require("async");



var mysql      = require('mysql');

var connection = mysql.createConnection({

  host     : 'localhost',

  user     : 'root',

  password : '',

  database : 'betfair'

});



connection.connect(function(err) {

  if (err) {

    console.error('error connecting: ' + err.stack);

    return;

  }



  console.log('connected as id ' + connection.threadId);

});



var url = 'https://www.betfair.com/sport/football';



var customHeaderRequest = request.defaults({

    headers: {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.133 Safari/537.36'}

})



customHeaderRequest.get(url, async function(err, resp, body){

  try {

    let $ = cheerio.load(body);

    let links = $('.section-list .section:nth-child(2) .event-list li').toArray();

    for (let link of links) {



        const id = $(link).find('.event-information .avb-col-markets a:nth-child(1)').attr('href');

        const idx = id.replace('/sport/football/event?eventId=', '');



        const home = $(link).find('.event-information div:nth-child(3) div a div span.team-name:nth-child(1)').text().trim();

        const away = $(link).find('.event-information div:nth-child(3) div a div span.team-name:nth-child(2)').text().trim();



        const x1 = $(link).find('.event-information .avb-col-markets .market-3-runners .runner-list li:nth-child(1) a .ui-runner-price').text().trim();

        const x = $(link).find('.event-information .avb-col-markets .market-3-runners .runner-list li:nth-child(2) a .ui-runner-price').text().trim();

        const x2 = $(link).find('.event-information .avb-col-markets .market-3-runners .runner-list li:nth-child(3) a .ui-runner-price').text().trim();



        const over = $(link).find('.event-information .avb-col-markets .market-2-runners .runner-list li:nth-child(1) a .ui-runner-price').text().trim();

        const under = $(link).find('.event-information .avb-col-markets .market-2-runners .runner-list li:nth-child(2) a .ui-runner-price').text().trim();

        if (home && away) {



          connection.query("INSERT INTO bf (id, home, away, x1, x, x2, over, under) VALUES ('"+idx+"', '"+home+"', '"+away+"', '"+x1+"', '"+x+"', '"+x2+"', '"+over+"', '"+under+"')", function (err, result) {

            if (err) throw err;

          });

        }

    }

  } catch(e) {

  }

});

I have tried plenty of thinks but im not that good in nodejs and i am looking for your help

Thanks

You didn't mention what the error is but I guess you don't really need the id so removing it will be OK.

P.S. Your code has many more issues, the most important one is the sql query.

You should use knex or at least change it to:

INSERT INTO bf (home, away, x1, x, x2, over, under) VALUES (?, ?, ?, ?, ?, ?, ?)",
[home, away, x1, x, x2, over, under], function (err, result) {
