When users want to delete a record, they must first find that record in the database. Accordingly, you need a search and a results page to work with the delete page. The user enters search criteria in the search page and selects the record on the results page. When the user clicks the record, the delete page opens and displays the record in an HTML form.
For instructions on creating pages to search for the record to delete, see Building search/results pages (ColdFusion, ASP, JSP, PHP).
After creating the search/results pages, the next step is to create links on the results page to let users select a record to delete and display a confirmation page. See Creating links to a confirmation page (ColdFusion).
