The option to have a delete page is on step 1 of the wizard, bottom item of the six options in the pages section.
You need a results page by default, but the other 5 pages are optional.
You mention the user deleting the database, I assume you mean record ? the delete button will not delete the database.
If you already have the results page with the delete buttons, simply remove the buttons (and the table rows which contain them), and then remove the delete page.
