JdbcRowSet Query Statement with Parameters
This section describes how to define parameters in the query statement of a JdbcRowSet object.
When you call the setCommand() method to provide the SELECT query statement, you can define some parameters in the same way as a PreparedStatement. Here is a sample program showing you set parameters and provide parameter values:
/* MySqlRowSetParameter.java * Copyright (c) HerongYang.com. All Rights Reserved. */ import java.sql.*; import javax.sql.rowset.RowSetProvider; import javax.sql.rowset.JdbcRowSet; public class MySqlRowSetParameter { public static void main(String [] args) { try { // RowSetFactory should be used now // JdbcRowSet jrs // = new com.sun.rowset.JdbcRowSetImpl(); JdbcRowSet jrs = RowSetProvider.newFactory().createJdbcRowSet(); // Set the connection URL for the DriverManager jrs.setUrl("jdbc:mysql://localhost/HerongDB" +"?user=Herong&password=TopSecret"); // Set a SQL statement with a parameter jrs.setCommand("SELECT * FROM Profile WHERE ID = ?"); // Set parameter values jrs.setInt(1, 30028); // Connect and run the statement jrs.execute(); jrs.next(); System.out.println("User #30028: " +jrs.getString("FirstName")+" "+jrs.getString("LastName")); // Repeating for another parameter value jrs.setInt(1, 30027); jrs.execute(); jrs.next(); System.out.println("User #30027: " +jrs.getString("FirstName")+" "+jrs.getString("LastName")); // Close resource jrs.close(); } catch (Exception e) { System.err.println("Exception: "+e.getMessage()); } } }
The parameter in this program represents the ID value in the Profile table. You may need to change the parameter values if your Profile table has different ID values. Here is the output of the program:
User #30028: 2438 bed51 User #30027: f5a 2c5c6
