public static void main (String args []) throws Exception
//DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@localhost:1516:ORAL", "name", "ps");
// @machineName:port:SID, userid, password
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery("select id from sample_table");
while (rset.next())
System.out.println (rset.getString(1)); // Print col 1
stmt.close();
}
