Creating CallableStatement Objects with prepareCall()

This section describes how to create a CallableStatement object with the prepareCall() method.

The first test I did was to create a CallableStatement with the prepareCall() method to call my simple procedure, UpdatePoint:

/* OracleCallableStatement.java
 * Copyright (c) HerongYang.com. All Rights Reserved.
 */
import java.sql.*;
public class OracleCallableStatement {
  public static void main(String [] args) {
    Connection con = null;
    try {
      oracle.jdbc.pool.OracleDataSource ds
        = new oracle.jdbc.pool.OracleDataSource();
      ds.setDriverType("thin");
      ds.setServerName("localhost");
      ds.setPortNumber(1521);
      ds.setDatabaseName("XE");
      ds.setUser("Herong");
      ds.setPassword("TopSecret");
      con = ds.getConnection();

// Create CallableStatement
      CallableStatement cs = con.prepareCall("CALL UpdatePoint()");

// Execute the call statement
      cs.execute();

// Close resource
      cs.close();

// Check execution result
      Statement sta = con.createStatement();
      ResultSet res = sta.executeQuery(
        "SELECT * FROM Profile WHERE FirstName LIKE 'Herong'");
      res.next();
      System.err.println("Point: "+res.getInt("Point"));
      res.close();
      sta.close();

      con.close();
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

Compilation and execution went ok. The output confirms that UpdatePoint was executed correctly:

herong> java -cp .;ojdbc11.jar OracleCallableStatement
Point: 2

herong> java -cp .;ojdbc11.jar OracleCallableStatement
Point: 3
