Java OCA OCP Practice Question 2912

Question

Suppose that the table animal has five rows and this SQL statement updates all of them.

What is the result of this code? 

public static void main(String[] args) throws SQLException { 
   Connection conn = DriverManager.getConnection("jdbc:derby:zoo"); 
   Statement stmt = conn.createStatement(); 
   int result = stmt.executeUpdate("update animal set name = name"); 
   System.out.println(result); 
}
  • A. 0
  • B. 1
  • C. 5
  • D. The code does not compile.
  • E. A SQLException is thrown.
  • F. A different exception is thrown.


C.

Note

This code works as expected.

It updates each of the five rows in the table and returns the number of rows updated.

Therefore, choice C is correct.
