Node.js MySQL Insert Records

INSERT INTO statement is used to insert records in MySQL.

Create a js file named "insert" in DBexample folder and put the following data into it:

1. var mysql = require('mysql');  
2. var con = mysql.createConnection({  
3. host: "localhost",  
4. user: "root",  
5. password: "12345",  
6. database: "javatpoint"  
7. });  
8. con.connect(function(err) {  
9. if (err) throw err;  
10. console.log("Connected!");  
11. var sql = "INSERT INTO employees (id, name, age, city) VALUES ('1', 'Ajeet Kumar', '27', 'Allahabad')";  
12. con.query(sql, function (err, result) {  
13. if (err) throw err;  
14. console.log("1 record inserted");

16. ];  
17. con.query(sql, [values], function (err, result) {  
18. if (err) throw err;  
19. console.log("Number of records inserted: " + result.affectedRows);
