PreparedStatement Overview

This section provides an overview of PreparedStatement.

If you have a SQL statement that needs to be executed multiple times, it is more efficient to use a JDBC PreparedStatement object to run it. JDBC PreparedStatement class supports the following main features:

A PreparedStatement object should be created from a Connection object with the prepareStatement() method and executed like a regular Statement object as shown in the following program:

/* OraclePreparedSelect.java

 */
import java.sql.*;
public class OraclePreparedSelect {
  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();

// PreparedStatement for SELECT statement
      PreparedStatement sta = con.prepareStatement(
	"SELECT * FROM Profile WHERE ID = 2");

// Execute the PreparedStatement as a query
      ResultSet res = sta.executeQuery();

// Get values out of the ResultSet
      res.next();
      String firstName = res.getString("FirstName");
      String lastName = res.getString("LastName");
      System.out.println("User ID 2: "+firstName+' '+lastName);

// Close ResultSet and PreparedStatement
      res.close();
      sta.close();

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

The output looks correct:

C:\herong>\Progra~1\java\jdk1.8.0_45\bin\javac
   -cp .;\local\lib\ojdbc6.jar
   OraclePreparedSelect.java

C:\herong>\Progra~1\java\jdk1.8.0_45\bin\java
   -cp .;\local\lib\ojdbc6.jar
   OraclePreparedSelect
