I got it (allthough i can probably leave out the joins). I still would like to know how to put the values into the array, but this is the query:

SELECT DISTINCT wposts.*
        FROM $wpdb->posts wposts
        JOIN $wpdb->postmeta wpostmeta ON wpostmeta.post_id = wposts.ID
        JOIN $wpdb->postmeta wpostmeta2 ON wpostmeta2.post_id = wposts.ID
        JOIN $wpdb->postmeta wpostmeta3 ON wpostmeta3.post_id = wposts.ID
        WHERE wposts.ID = wpostmeta.post_id
        AND wposts.ID = wpostmeta2.post_id
        AND wposts.ID = wpostmeta3.post_id
        AND wpostmeta.meta_key = 'event_date'
        AND wpostmeta2.meta_key = 'event_time'
        AND wpostmeta3.meta_key = 'location'
        ORDER BY wpostmeta.meta_value ASC, wpostmeta2.meta_value ASC, wpostmeta3.meta_value ASC'

The question wasn’t very clear. So I’ll try it again.

In 1 template I want to show all posts of the category program. A post contains besides the usual fields some custom values: event_date, event_time, location and 2 or 3 more.
I want to display the posts ordered by event_date, event_time and then by location.

What function or sql statement do I need to use in order to get an array of posts in that specific order?
