Retrieving single field with no filtering parameters is not implemented in OQL yet. We will have this functionality in one of our next releases and until then I can recommend you to workaround this using Linq query like:
var result = (from a in scope.Extent<MyGuidClass>()
I also would like to introduce to you our Knowledge-Base
. It should serve you to advance with OpenAccess more quickly.
I hope this was helpful and I’m looking forward for your feedback.
