Java Programming Multiple Choice Question

Which of these code lines related to the Statement-type object is true?

statement.executeUpdate("select * from employees");

statement.executeQuery("delete from employees");

statement.execute("select * from employees");

statement.executeQuery("select * from employees");

All of the above.

statement.executeUpdate("select * from employees");

statement.executeQuery("delete from employees");

statement.execute("select * from employees");

statement.executeQuery("select * from employees");

All of the above.

Option d.

-For sql statements relate to queries we use executeQuery(query_sql) method.

-For sql statements related to Updating the existing row or inserting a new row or for Deleting the row we use executeUpdate(sql) method.

- Only exceute() method is used for executing DDL statements.

- Based on the above information we can see that all the sql statements except the query sql statement, are calling the wrong execute() method.

So option d is correct.
