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 Worldthat’s all folks!
