How do I move to absolute or relative row?
Category: java.sql, viewed: 2K time(s).
In this example we are showing you how to use result set abosule() and relative() method to jump from one result set row to the other. When you pass a positive number as the parameter you'll move from the first record to the last. But if you pass a negative number as parameter you'll move from the last record backward.
package org.kodejava.example.sql;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class MoveAbsoluteOrRelativeExample {
public static void main(String[] args) throws Exception{
Connection connection = null;
try {
Class.forName("com.mysql.jdbc.Driver");
connection = DriverManager.getConnection("jdbc:mysql://localhost/testdb", "root", "");
Statement statement = connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
ResultSet resultSet = statement.executeQuery("SELECT * FROM products");
//
// Move to the second row
//
resultSet.absolute(2);
System.out.println("You are now in: " + resultSet.getRow());
//
// Move 2 records forward from the current position (fourth row)
//
resultSet.relative(2);
System.out.println("You are now in: " + resultSet.getRow());
//
// Move to the last row in the result set
//
resultSet.absolute(-1);
System.out.println("You are now in: " + resultSet.getRow());
//
// Move 3 records backward from the current position (second row)
//
resultSet.relative(-3);
System.out.println("You are now in: " + resultSet.getRow());
} catch (SQLException e) {
e.printStackTrace();
} finally {
if (connection != null) {
connection.close();
}
}
}
}
