body: <p>I got a function like getItemPrice in nodeJS. But while trying to inserting datas there is a error occuring. Can't write any dynamic value inside VALUES(item.Id, value.lowest_price).</p>
  
  <p>I've tried lots of things bot none of work.</p>
  
  <pre><code>con.query('SELECT game_item.id as itemId, steam_app_game.app_id as gameId, game_item.name, steam_app_game.id FROM steam_app_game LEFT JOIN game_item ON steam_app_game.id = game_item.app_game_id', function(err, rows, fields) {
  var counter = 1;
  rows.forEach(function (item,index) {
          setTimeout(function(){
              market.getItemPrice(item.gameId, item.name).then(function (value, err) {
                  if(err) throw  err;
                  var lowest = value.lowest_price
                  con.query('INSERT INTO game_item_spec(game_item_id,price) VALUES (item.itemId,value.lowest_price )')
                  counter ++;
              });
          }, index * 5000);
      });
  });
