    Insert more than one record, make an array containing the values, and insert a question mark in the sql, which will be replaced by the value array :

connection.query(query, [data]);

    Example :

var mysql = require('mysql');

var con = mysql.createConnection({
  host: "localhost",
  user: "your_username",
  password: "your_password",
  database: "websolutionstuff"
});

con.connect(function(err) {
  if (err) throw err;
  console.log("Connected..!");
  var sql = "INSERT INTO users (name, email) VALUES ?";
  var values = [
    ['websolutionstuff', '[email protected]'],
    ['dell', '[email protected]'],
    ['laravel', '[email protected]']
  ];
  con.query(sql, [values], function (err, result) {
    if (err) throw err;
    console.log("Number of records inserted: " + result.affectedRows);
  });
});
