jdbc hello world

I am in a java mood today, let’s check how to print hello world with jdbc :)

import java.sql.*;
public class HelloWorld {
  public  static void main(String[] args) throws SQLException {
    DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
    ResultSet res = DriverManager.
      getConnection("jdbc:oracle:thin:@srv1:1521:DB01", "scott", "tiger").
      prepareCall("select 'Hello World' txt from dual").
      executeQuery();
    res.next();
    System.out.println(res.getString("TXT"));
  }
}

let’s compile
javac -classpath $ORACLE_HOME/jdbc/lib/classes12.jar HelloWorld.java

and run

$ java -classpath $ORACLE_HOME/jdbc/lib/classes12.jar:. HelloWorld
Hello World

that’s all folks!
