To close the database session after examining the results of an SQL query, you can use the close method for the RecordSet and Connection objects.
Let's go through each option to understand why it is correct or incorrect:
Option A) Call the ADO.Close function - This option is incorrect because there is no specific ADO.Close function to close the database session. ADO (ActiveX Data Objects) is a library used for database access, but it doesn't have a Close function for closing the session.
Option B) Use the close method for the RecordSet object - This option is incorrect because closing only the RecordSet object is not sufficient to close the entire database session. The RecordSet object represents the results of the query, but there is still an active connection to the database that needs to be closed.
Option C) Set the RecordSet and Connection objects equal to Nothing - This option is incorrect because setting the objects equal to Nothing in many programming languages is a way to release the memory occupied by the objects, but it does not close the actual database session. It may help with memory management, but the session connection will still remain open.
Option D) Use the close method for the RecordSet and Connection objects - This option is correct because it ensures that both the RecordSet object and the Connection object are closed properly. By calling the close method for both objects, you are closing the database session and releasing any resources associated with it.
The correct answer is D. Using the close method for the RecordSet and Connection objects. This option is correct because it closes both the RecordSet object and the Connection object, effectively closing the entire database session.
