Create links to the update page
After creating the search and results pages, you create links on the results page to open the update page. You then
modify the links to pass the IDS of the records the user selects. The update page uses this ID to find the requested
record in the database and display it.
You use the same process to open the update page and pass a record ID that you do to open a detail page and pass a
record ID. For more information, see "Create links to the detail page" on page 617.
