set CCK default value from query (Multi-Value)
Just in case you may need to populate a CCK field from a db query OR more to the point, next time I have to:
$qdata= 'db_query(SELECT field_school_studyareas_value
where nid in (select nid from node WHERE node.type in ("exhibitor_profile") and uid ='.$user->uid.')) ' ;
Yes a join would have been far better. I'll fix that soon.
