public static void main(String[] args) {
String url = "jdbc:teradata://hostname:port/database=dbname";
String username = "username";
String password = "password";
try {
Connection conn = DriverManager.getConnection(url, username, password);
System.out.println("Connected to Teradata database successfully!");
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}

import java.sql.SQLException;
import java.sql.Statement;
public class TeradataQueryExample {
public static void main(String[] args) {
String url = "jdbc:teradata://hostname:port/database=dbname";
String username = "username";
String password = "password";
try {
Connection conn = DriverManager.getConnection(url, username, password);
Statement stmt = conn.createStatement();
String sql = "SELECT * FROM your_table";
ResultSet rs = stmt.executeQuery(sql);
while (rs.next()) {

public static void main(String[] args) {
String url = "jdbc:teradata://hostname:port/database=dbname";
String username = "username";
String password = "password";
try {
Connection conn = DriverManager.getConnection(url, username, password);
Statement stmt = conn.createStatement();
String sql = "UPDATE your_table SET column1 = value WHERE condition";
