Receiving ResultSet Objects from executeQuery

This section describes how to receive the ResultSet object returning from the executeQuery() method.

When you execute a SQL SELECT statement with the executeQuery() method, you need receive the returning ResultSet object with a variable. This ResultSet object variable represents the data that are generated by the SELECT query statement.

There are two types of methods available on the ResultSet object:

The tutorial below shows you how to receive the ResultSet object and the value from the first column of the first row:

import java.sql.*;
public class GetServerDate {
  public static void main(String [] args) {
    Connection con = null;
    try {

// Obtaining a connection to SQL Server
      con = DriverManager.getConnection(
        + "user=herong;password=T0pSecret;"
        + "database=AdventureWorks2019");

// Checking the database name
      Statement sta = con.createStatement();
      ResultSet res = sta.executeQuery("SELECT GETDATE()");;
      Date today = res.getDate(1);
      System.out.println("Server date: "+today);

    } catch (Exception e) {

If you run this program, you will get something like this:

herong> java -cp .;mssql-jdbc-9.4.1.jre16.jar

Server date: 2022-01-01
