In this tutorial we will see how to insert data into MySQL table using Node.js. In previous node .js article I will give you example about how to connect MySQL database with Node.js and how to create MySQL database in Node.js.

So, now I will give you information about insert rows into mysql database table from node.js or insert multiple records into mysql using node.js. Before perform this article please make sure create database with connection. So, read below tutorial for connect database.

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 ('websolutionstuff', '[email protected]')";
  con.query(sql, function (err, result) {
    if (err) throw err;
    console.log("Record Inserted Successfully!");
  });
});

Run db_record_demo.js file

node db_record_demo.js

The response with console messages like

Connected..!!
Record Inserted Successfully!

 

 

Insert Multiple Records

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 :

INSERT INTO users (name, email) VALUES ?

Use query() method with SQL statement and data array like below :

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);
  });
});

Run db_record_demo.js file

node db_record_demo.js

The response with console messages like :

Connected..!!
Number of records inserted: 3
