JDBC : Find Lowest salary

In this tutorial, we are showing how to find record of lowest salary in table employee.

MIN() :

MIN() method returns the lowest value of the specified field. So when you want to get lowest value of any numeric field just use MIN method in your query as -

sql = SELECT MIN(salary) FROM employee

Employee Table :  -

Example : In the following example we are displaying record of such employee who has lowest salary among all. For that we are using MIN() function.

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

class JDBCMinSalary {
	public static void main(String[] args) {
		System.out.println("Finding Lowest salary Example...");
		Connection conn = null;
		String url = "jdbc:mysql://localhost:3306/";
		String dbName = "employees";
		String driverName = "com.mysql.jdbc.Driver";
		String userName = "root";
		String password = "root";
		Statement statement = null;
		ResultSet rs;
		try {
			Class.forName(driverName);
			conn = DriverManager
					.getConnection(url + dbName, userName, password);
			statement = conn.createStatement();

			String sql = "SELECT * FROM employee WHERE salary=(SELECT MIN(salary) FROM employee)";

			rs = statement.executeQuery(sql);
			System.out.println("EmpId\tName\tSalary");
			System.out.println("----------------------");
			while (rs.next()) {
				int roll = rs.getInt("emp_id");
				String name = rs.getString("name");
				long salary = rs.getLong("salary");

				System.out.println(roll + "\t" + name + "\t" + salary);

			}

			conn.close();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

Output :
