JDBC: Last Inserted Id Example

In this tutorial, you will learn how to find last inserted record ID using JDBC API.

Getting Last Inserted ID : Last inserted Id is required for further insertion, so that you use correct id for next insertion.  you can get the last inserted id by using MAX(), writing query as -

 sql = "SELECT MAX(roll_no) from student";

Example :  In this example we are finding the roll_no of last inserted record of student table.

package jdbc;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

class LastInsertId {
	public static void main(String[] args) {
		System.out.println("Last inserted Id Example...");
		Connection con = null;
		Statement statement = null;
		ResultSet rs = null;
		String url = "jdbc:mysql://localhost:3306/";
		String dbName = "students";
		String driverName = "com.mysql.jdbc.Driver";
		String userName = "root";
		String password = "root";
		try {
			// Connecting to the database
			con = DriverManager.getConnection(url + dbName, userName, password);
			try {
				// Creating object of Statement
				statement = con.createStatement();

				// Finding id of last inserted record
				String sql = "SELECT MAX(roll_no) from student";
				rs = statement.executeQuery(sql);
				while ( {
					System.out.println("Id of Last inserted student record : "
							+ rs.getInt(1));
			} catch (SQLException e) {
		} catch (Exception e) {

Output :
