updatedp (alias: updb)

drush updb

In order to update the database, simply type "drush updb". You'll be shown a list of pending updates and asked if you'd like to run all pending updates. I'll type "y" and push enter.

That's all there is to it!

This accomplishes the same thing as going to "/update.php" on your website, and following the prompts there, but is significantly faster.
