Determine if a database supports Updatable ResultSets

This is an example of how to determine if a database supports updatable ResultSets. When a database supports updatable ResultSets it means that modification to data in a table is allowed through a result set. Checking if a database supports updatable ResultSets implies that you should:

  • Load the JDBC driver, using the ForName(String className) API method of the Class. In this example we use the MySQL JDBC driver.
  • Create a Connection to the database. Invoke the getConnection(String url, String user, String password) API method of the DriverManager to create the connection.
  • Create a DatabaseMetaData, using the getMetaData() API method. The metadata includes information about the database, including the capabilities of this connection.
  • Check if the database supports updatable ResultSets. Invoke the supportsResultSetConcurrency(int type, int concurrency) API method of the DatabaseMetaData.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.core;

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

public class UpdatableResultSetDatabaseSupport {
  public static void main(String[] args) {

    Connection connection = null;
    try {

  // Load the MySQL JDBC driver

  String driverName = "com.mysql.jdbc.Driver";


  // Create a connection to the database

  String serverName = "localhost";

  String schema = "test";

  String url = "jdbc:mysql://" + serverName +  "/" + schema;

  String username = "username";

  String password = "password";

  connection = DriverManager.getConnection(url, username, password);


  System.out.println("Successfully Connected to the database!");

    } catch (ClassNotFoundException e) {

  System.out.println("Could not find the database driver " + e.getMessage());
    } catch (SQLException e) {

  System.out.println("Could not connect to the database " + e.getMessage());

    try {

  DatabaseMetaData metadata = connection.getMetaData();

  if (metadata.supportsResultSetConcurrency(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_UPDATABLE)) {

System.out.println("Updatable result sets are supported");

  } else {

System.out.println("Updatable result sets are not supported");


    } catch (SQLException e) {

  System.out.println("Could not get database metadata " + e.getMessage());


Example Output:

Successfully Connected to the database!
Updatable result sets are supported
