yes, 'db' is unknown what it is and indeed the qf isn't used so I think linq and queryspec are mixed here.
Ah, yes, I must have been reading the QuerySpec stuff, while in this case db is a Linq metadata object. The wide range of options for querying data makes it very tricky to work out how to perform non-trivial operations like this.
qf
was introduced as a test after I crashed and burned trying to use PrefetchPathStreamrow in a Linq operation, so presumably that property serves no purpose in a Linq based operation chain?
