Inserting Records using the Prepared Statement
In this section we are going to learn how we will insert the records in the database table by using the PreparedStatement interface of java.sql package. As we all know that in database all records are added in the table in a tabular format like: rows and columns. See brief description below:
Description of program:
This program will perform the work for inserting the records in 'movies' database table. For this, first of all we need to establish the connection with MySQL database by using the JDBC driver. When the connection has been established then we will pass a SQL statement in the prepareStatement that returns the PreparedStatement object. After setting the values of movie name and release year the values are inserted in the movies table by the help of executeUpdate method then it will show a message "row(s) affected" otherwise display "SQL statement is not executed!" . The executeUpdate method also executes the SQL statement (INSERT, UPDATE, DELETE) at the time of inserting, updating and deleting the records from the database table.
Here is the code of program:
import java.io.*;
import java.sql.*;
public class InsertRecords{
public static void main(String[] args) {
System.out.println("Insert records example using prepared statement!");
Connection con = null;
try{
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection("jdbc:mysql:
//localhost:3306/jdbctutorial","root","root");
try{
String sql = "INSERT movies VALUES(?,?)";
PreparedStatement prest = con.prepareStatement(sql);
BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter movie name:");
String mov = bf.readLine();
prest.setString(1, mov);
System.out.println("Enter releases year of movie:");
int year = Integer.parseInt(bf.readLine());
prest.setInt(2, year);
int count = prest.executeUpdate();
System.out.println(count + "row(s) affected");
con.close();
}
catch (SQLException s){
System.out.println("SQL statement is not executed!");
}
}
catch (Exception e){
e.printStackTrace();
}
}
}
Database Table: movies
| title | year_made |
| alam ara | 1945 |
| Bagal bali | 2002 |
| Diwar | 1980 |
| Nadia ke par | 1975 |
| Karan | 1996 |
| Ramayan | 1966 |
| Yarana | 1988 |
| Muhabte | 1998 |
Output of program:
| C:\vinod\jdbc\jdbc\PreparedStatement>javac InsertRecords.java C:\vinod\jdbc\jdbc\PreparedStatement>java InsertRecords Insert records example using prepared statement! Enter movie name: Bagban Enter releases year of movie: 2003 1row(s) affected |
After executing the program:
