We have some sample content for some of the simpler tables for the Kings project. Had to download and install a new copy of MySQL Workbench (it's not in the repos) to get work on the file; it got nuked when my system died the other week. Initially I had the dreaded "err 150" which prevented me from building four of the tables in the db. This is a famously unhelpful and mysterious error message. It turned out that one of the foreign keys in each of these tables was pointing to a column in another table that should have been a primary key, but wasn't. That error always takes ages to figure out. But the DB is built now.
