Jonathan Daggerhart: Database Interactions with WP_Query and $wpdb

This session teachs developers how to write custom WP_Query loops, the different functions available for interacting with WP_Query objects, and how to use each function appropriately. We discuss the cases where WP_Query doesn’t fit your needs, and how to deal with the global $wpdb object directly. And we look at the most useful methods available with the $wpdb object, and discuss responsible usage and implementation there of.
