Joseph,

Can you explain more about what you want to achieve using a join? or why
you think you need to use a join?

Typically joins are only supported on QUERY with a template if you are
using shapefiles. If you are looking to use a join for say
classification of polygons for thematic mapping you should probably look
into moving all your data into PostGIS as it it not supported for
shapefiles (much to my consternation and occasional prodding otherwise).
