Quick check of code sanity

All,

I have the following call that worked a-ok in WP 1.5, that seems to fail to retrieve valid data under v 2.0 (yes I know it’s not in general release yet), but someone might be able to spot the goof.

Code snippet:

<?php $sidenote_cat = $wpdb->get_var("SELECT cat_ID FROM $wpdb->categories WHERE category_nicename = 'asides'"); ?>

Under 1.5, that will (obviously) perform a valid mySQL lookup, under 2.0 it fails to actually generate any result (it’s used before the_post loop). Is there anything new I need to add to ensure I’m making the right db calls?

Cheers,
Brendan.
