Select Records Using Prepared Statement

     

In this section we will learn how to select some specific records by using the PreparedStatement. We know that the PreparedStatement object  represents a precompiled SQL statement. See brief information below:

Description of program:

In this program firstly we need to establish the connection with MySQL database by using the JDBC driver. After establishing the connection we pass the necessary SQL query in the prepareStatement method. This method returns the PreparedStatement object. According to the conditions given in the query the result will be displayed to the user. Here we are displaying all records between 1980 and 2004 in the movies database table and it displays the number of records that follows this conditions. If any problems arises in that process it shows a message "SQL statement is not executed!".

Here is the code of program:

import java.sql.*;

public class SelectRecords{
  public static void main(String[] args) {
  System.out.println("Select Records Example by using the Prepared Statement!");
  Connection con = null;
  int count = 0;
  try{
  Class.forName("com.mysql.jdbc.Driver");
  con = DriverManager.getConnection
("jdbc:mysql://localhost:3306/jdbctutorial","root","root");
  try{
  String sql 
= "SELECT title,year_made FROM movies WHERE year_made >= ? AND year_made <= ?";
  PreparedStatement prest = con.prepareStatement(sql);
  prest.setInt(1,1980);
  prest.setInt(2,2004);
  ResultSet rs = prest.executeQuery();
  while (rs.next()){
  String mov_name = rs.getString(1);
  int mov_year = rs.getInt(2);
  count++;
  System.out.println(mov_name + "\t" + "- " + mov_year);
  }
  System.out.println("Number of records: " + count);
  prest.close();
  con.close();
  }
  catch (SQLException s){
  System.out.println("SQL statement is not executed!");
  }
  }
  catch (Exception e){
  e.printStackTrace();
  }
  }
}
