Predict and justify the output of the following code snippet written by the developer to update the Status table: String str = "UPDATE m_id SET m_id= ? WHERE bk_id= ? "; PreparedStatement ps = con.prepareStatement(str); ps.setString(1, "m2"); ps.setString(2, "bk23"); int rt=ps.executeUpdate();

import java.sql.*;
class UpdateData{
public static void main(String[] args){
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/roseindia", "root", "root");
String str = "UPDATE Status SET name= ?,value=? WHERE id= 1 ";
PreparedStatement ps = con.prepareStatement(str);
ps.setString(1, "m2");
ps.setString(2, "bk23");
ps.executeUpdate();
}
catch(Exception e){
System.out.println(e);
}
}
}
For the above code, we have created following table:
CREATE TABLE `status` (
`id` bigint(255) NOT NULL auto_increment,
`name` varchar(255) default NULL,
`value` varchar(255) default NULL,
PRIMARY KEY (`id`)
);
