discipline is its own table, not a column, so i'd need to throw a join
in there. I have another table, showcase_discipline to relate from
showcases. I did it this way because there are several other tables that
rely on disciplines (one to one and many to one).
And thanks for the ORDER BY tip! I had no idea i could do that. I'll see
if i can work that in.
