title: How can I insert a post into wordpress and associate it with a category?
body: <p>I have content from elsewhere that I would like to insert as a post in Wordpress and then associate with an existing category.  It is pretty straightforward to insert a new post into the wp_posts table, but I can't seem to figure out how to construct a query to both insert a new post and at the same time associate the post with a category.  How would one go about doing this?</p>
  
  <p>If it helps, I am using WordPress 2.8</p>
