That's usually bad...

But that doesn't mean that ONE more DB query will kill you.

And there are times when the JOINs for the one-query solution will kill you anyway, but with proper pagination, the dozen multi-query solution will zip along merrily.

What is "good" for the DB storage and what users end up wanting collated on a page are occasionally at odds, especially for the admin pages.

If you've tweaked the front-facing user side and correctly laid-out the DB for maximum scalability for the users, the admin side can sometimes be a bit hairy like that...

Which is fine, since the admin side is much less trafficked.

Short Version:
Sometimes you should break the rules. Knowing when is called "experience"
