updateXXX() - Updating Column Values for Row Update or Insert

This section describes updateXXX() methods used to update column values for the current row for database update or the insert row for inserting a new row.

When a ResultSet object is created with update capability, you can call updateXXX() methods to update column values to prepare for calling updateRow() or insertRow() method store the updated row or a new row to the target table. All updateXXX() methods support two types of parameters to specify a column:

JDBC supports many updateXXX() methods, one for each Java data type, so that you can set column values directly with the desired Java data types without any conversion. Here is a list of updateXXX() methods:

Here is sample program that uses different updateXXX() methods to set column values with different data types:

/* DerbyUpdateMethods.java

import java.sql.*;
public class DerbyUpdateMethods {
  public static void main(String [] args) {
    Connection con = null;
    try {
      con = DriverManager.getConnection("jdbc:derby://localhost/TestDB");

// Create a Statement for scrollable ResultSet
      Statement sta = con.createStatement(

// Catch the ResultSet object
      ResultSet res = sta.executeQuery(
        "SELECT * FROM Profile WHERE 1=2");

// Check ResultSet's updatability
      if (res.getConcurrency() == ResultSet.CONCUR_READ_ONLY) {
        System.out.println("ResultSet non-updatable.");
      } else {
        System.out.println("ResultSet updatable.");

// Move the cursor to the insert row

// Prepare column values in different data types
      String firstName = "Alex";
      String lastName = "King";
      double points = 654.321;
      Date birthDate = Date.valueOf("1966-06-06");
      Timestamp now = new Timestamp(System.currentTimeMillis());

// Set the new first name and last name
      res.updateString("FirstName", firstName);
      res.updateString("LastName", lastName);
      res.updateDouble("Point", points);
      res.updateDate("BirthDate", birthDate);
      res.updateTimestamp("ModTime", now);

// Store the insert into database

// Move the cursor back to the current row

      System.out.println("Row inserted ok.");

// Close ResultSet and Statement

    } catch (Exception e) {
      System.err.println("Exception: "+e.getMessage());

Note that the Date class used in this program is from the java.sql.* package, not from the java.util.* package. There is no problem with the execution:

ResultSet updatable.
Row inserted ok.
