Java OCA OCP Practice Question 3190

Question

Assume that you've freshly created this table with the following command in MySQL: 

create table familyGroup (
id int not null auto_increment, 
nickName varchar(30) Not null, 
primary key (id));

You've written this program that makes use of this table: 

import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class Main {
     public static void main(String[] args) throws SQLException {
             try (Connection connection = DbConnector.connectToDb();
                     Statement statement =
                      connection.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
                     ResultSet resultSet =statement.executeQuery("SELECT * FROM familyGroup")) {
                     resultSet.moveToInsertRow();
                     resultSet.updateString("nickName", "Sam");
                     resultSet.insertRow();  // INSERT ROW
                     System.out.println("Table updated with a row. . .");
                     connection.commit();    // COMMIT STMT
             }//from   w  w  w.  j  av  a  2  s . c  o  m
     }
}

What will be the result of executing this program assuming that establishing the connection succeeds? 

A.The program will successfully insert a row with id = 1 and nickName = "Sam".
B.A SQLException will be thrown in the line where the INSERT ROW comment is provided because you cannot insert a row on a read-only ResultSet object.
C.A SQLException will be thrown in the line where the COMMIT STMT statement is provided because auto-commit is enabled; hence the commit will fail.
D.The program will not insert anything into the *familyGroup* table.



C.

Note

Any attempt to use methods such as commit, rollback, setSavepoint(), etc. will result in throwing a SQLException if auto-commit is not disabled.
