Specifically I’ve been trying to implement a many-to-many relation where the intermediate table has attributes, and then do a join across this table filtered by these attributes.  Trivial in SQL, and frustratingly difficult in SQLObject.  In fact I’ve shelved it for now while I concentrate on other issues.
