Prepared Statement With Batch Update
This section helps to use the PreparedStatement with
BatchUpdate and we are going to provide an example
that performs batch update facility. In batch update more than one records can
be added in the database simultaneously by using the some java methods like: addBatch
and executeUpdate.
First of all we are going to describe the Batch
Update.
A batch update is a collection of multiple update statements that provides the
facility for submitting in the database as a batch.
Description of program:
In this program firstly we have to
establish the connection with MySQL database by using the JDBC driver.
When the connection has been established we need to give the query in the prepareStatement
method and it returns PreparedStatement object. The data is submitted in
a batch
by the addBatch method and updates it by using the executeBatch
method of the PreparedStatement interface. If all records will get
added in the database then it will display a message
"Added Successfully!" and if any problem arises then it
throws an BatchUpdateException and it shows "SQL
statement is not executed!".
Here is the code of program:
import java.sql.*;
public class PreparedStatementBatchUpdate{
public static void main(String[] args) {
System.out.println("Prepared Statement Batch Update Example!");
Connection con = null;
try{
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection
("jdbc:mysql://localhost:3306/jdbctutorial","root","root");
try{
con.setAutoCommit(false);
String sql = "INSERT movies VALUES(?,?)";
PreparedStatement prest = con.prepareStatement(sql);
prest.setString(1,"Bagal bali");
prest.setInt(2,2002);
prest.addBatch();
prest.setString(1,"Raja Hindustani");
prest.setInt(2,1998);
prest.addBatch();
prest.setString(1,"Diwar");
prest.setInt(2,1980);
prest.addBatch();
prest.setString(1,"Nadia ke par");
prest.setInt(2,1975);
prest.addBatch();
int count[] = prest.executeBatch();
con.commit();
con.close();
System.out.println("Added Successfully!");
}
catch (BatchUpdateException s){
System.out.println("SQL statement is not executed!");
}
}
catch (Exception e){
e.printStackTrace();
}
}
}
