In 1.6, Vector->Join creates a new shapefile with the data in it. The
tab in 1.7 creates a dynamic join, which is preferable. If you use
PostGIS or SpatiaLite as a backend, you can use a view to do a dynamic
join in your spatial database, like so (in PostGIS):
CREATE VIEW geocode AS SELECT rooms.gid, rooms_centroids.room_no,
rooms.bldglevel, rooms.msg_en, rooms_centroids.the_geom
FROM rooms, rooms_centroids
WHERE rooms.room_no = rooms_centroids.room_no;
This creates a new view that uses the room_no and geometry from
rooms_centroids, and the gid, bldglevel and msg_en from rooms.

How can I link species occurrences with county names to the county shape file

Chris Buddenhagen
As the species occurrence list has county names, you could use a JOIN to link
the two files together.
In 1.6 it's in the vector menu list.
In 1.7 it's a tab in the layer properties dialogue.
QGIS is able to open non-spatial CSV or DBF format files through the Add Vector
system.
Does this help?
