If you want to create a question with a list of responses from which the respondent can choose several, and whose category lists are generated by connecting to an external database, use a multiple response database question type. For example: "Which of these types of coffee have you ever purchased?"

From the menu, choose Insert Question Database Question Multiple Response or press Alt+I, Q, D, D, P

The Data Link Properties dialog box displays, allowing you to provide the appropriate database provider and connection string information.
