∟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, HelloWorld():

/**
 * MySqlCallableStatement.java
 * Copyright (c) 2007 by Dr. Herong Yang. All rights reserved.
 */
import java.sql.*;
public class MySqlCallableStatement {
  public static void main(String [] args) {
    Connection con = null;
    try {
      com.mysql.jdbc.jdbc2.optional.MysqlDataSource ds 
        = new com.mysql.jdbc.jdbc2.optional.MysqlDataSource();
      ds.setServerName("localhost");
      ds.setPortNumber(3306);
      ds.setDatabaseName("HerongDB");
      ds.setUser("Herong");
      ds.setPassword("TopSecret");
      con = ds.getConnection();

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

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

// Close resource
      cs.close();

      con.close();
    } catch (Exception e) {
      System.err.println("Exception: "+e.getMessage());
      e.printStackTrace();
    }
  }
}

Compilation and execution went ok. There was no output from the program as expected:

C:\>javac -cp .;\local\lib\mysql-connector-java-5.0.7-bin.jar 
  MySqlCallableStatement.java

C:\java -cp .;\local\lib\mysql-connector-java-5.0.7-bin.jar
  MySqlCallableStatement
