As for specific query, well, start with a select query to retrieve the one (or more) entries you want to modify. Once that is successful, change the select to an update and identify the new value(s) you want to have in their place.
If still have an error with that, temporarily create a new field that is autonumber/unique so that phpmyadmin can play with it, then I suggest deleting that column. This is something I have done to make a "quick/bulk" change. (Lazily)
