[odb-users] Querying on Containers

[Lukas Obermann]

Hi Boris,

sorry für the delay.

So, I have this view:
#pragma db view \
object(main) \
object(ClassA = a: main::ptr_a) \
object(ClassA = list_a: main::list_a) \
object(ClassB = b: main::ptr_b)
...

So, accessing and querying 'a' and 'list_a' works perfectly.
but when now trying query:
query::b::ptr_c->iNeedToBeQueried == "SomeValues"
it simply does not know the 'iNeedToBeQueried' value.
Also tried:
query::b::ptr_c::iNeedToBeQueried == "SomeValues"
with the same result.

I assume that I somehow have to make ClassC visible within the view?

Thanks,
Lukas
