Are there any sample apps that use DoQuery to populate fields from another table.

yes, I'm working on a quote system with would either swarm the reference table with relationships or swarm the database with tables, having a single reference table is the sensible option but I'll need to get my head around doquery, I've got as far as I can with the code, but would like to see a working example to see what I've got wrong.  The Records and Ipsums example looks good but I can't access the properties, so any application with a working doquery would be great.
