How can I get every page in the posts table?

Hi, this is probably an easy thing but I’m having trouble getting at the posts table in a little plugin I’m writing. (first one actually)

I want all the feilds in every row with a post_type of page. I’ve tried using a query with $myrows = $wpdb->get_results($query); but wordpress returns this error:

Fatal error: Call to a member function get_results() on a non-object

Doesn’t seem to be a problem with the query. It does this on every query.

The result I want is like the get_post() function except I want to be able to loop through all the pages to get these values, not just one.

Any help would be appreciated!
