Question 1
Which of the following statements are true?
◦ You may create multiple statements from one connection.
◦ You can send queries and update statements through a Statement object.
◦ You may create multiple connections to a database.
◦ You may load multiple JDBC drivers in a program.
Question 2
Analyze the following code:
ResultSet resultSet = statement.executeQuery
| | ("select firstName, mi, lastName from Student where lastName " |
System.out.println(resultSet.getString(1));
◦ If the SQL SELECT statement returns no result, resultSet is null.
◦ resultSet.getString(1) returns the firstName field in the result set.
◦ resultSet.getString(1) returns the mi field in the result set.
◦ The program will have a runtime error, because the cursor in resultSet does not point to a row. You must use resultSet.next() to move the cursor to the first row in the result set. Subsequently, resultSet.next() moves the cursor to the next row in the result set.
