Is this what you are looking for? https://github.com/igor-tkachev/bltoolkit/blob/master/UnitTests/Linq/Model/ParentChild.cs#L503

I think that the only way to implement it is to give you access to SQL generation process. Somehow. No idea how.

What data provider do you use?

I think it can be implemented as a helper method in your project if you really need it.

Try the latest.

The ExecuteList method does not cache anything.

Usually GC takes as much memory as it can if other applications do not need it. So, I do not think this is a problem.

Try ``` var query = db.MyEntity.Select(s => s.Id).AsEnumerable().Union(new[] { 5 }); ```

Then I do not quite understand the problem.

This request is huge. I just need a lot of time to review it.
