Creating CallableStatement Objects with Parameters

This section describes how to create CallableStatement objects with IN and OUT parameters.

For an IN parameter defined in a stored procedure, you can put a static value or a place holder in the CALL statement when creating the CallableStatement object. A value for that place holder must be provided by the setXXX() method.

For an OUT parameter defined in a stored procedure, you must put a place holder in the CALL statement when creating the CallableStatement object. That place holder must be registered with the registerOutParameter() method.

In a previous tutorial, I defined a store procedure called, CountChar(), with 1 IN parameter and 1 OUT parameter. The program below shows you to create a CallableStatement object to execute this stored procedure:

 - Copyright (c) 2015,, All Rights Reserved.
import java.sql.*;
public class OracleCallParameter {
  public static void main(String [] args) {
    Connection con = null;
    try {
      oracle.jdbc.pool.OracleDataSource ds 
        = new oracle.jdbc.pool.OracleDataSource();
      con = ds.getConnection();

// Create CallableStatement
      CallableStatement cs = con.prepareCall(
        "CALL CountChar(?,?)");

// Provide values for IN parameters
      String word = "Herong";

// Register OUT parameters
      cs.registerOutParameter(2, java.sql.Types.INTEGER);

// Execute the CALL statement and ignore result sets

// Retrieve values from OUT parameters
      int length = cs.getInt(2);
      System.out.println("Input word: "+word);
      System.out.println("Word length: "+length);

// Close resource

    } catch (Exception e) {

The output of the program confirms that I handled IN and OUT parameters correctly:

   -cp .;\local\lib\ojdbc6.jar OracleCallParameter

Input word: Herong
Word length: 6
