First off, if your DB query is taking long enough to require a progress
indicator, you're probably writing horribly inefficient queries, and
could just make them run much quicker by proper use of indexes etc.

However, if you do need an indicator but don't need it to be an actual
progress bar as such (just showing that something's going on, as
opposed to how far through it is), then if you're using Javascript and
AJAXy stuff, just fire off the request to the server to fetch data via
AJAX, display a spinner, and when the response arrives, hide the
spinner and process the response data.
