Is it possible to eager load lazy Blobs, like it's possible for Associations?
For normal, there is no need to load these Blobs immediatly. But there is one part, where I could load them directly without using a second SQL-Statement...

That is unfortunately not possible yet.
would be a nice addition
I created this Feature Request
@Weetch_Russell just vote
I did the following as an efficient workaround:
// Getting Datas:
ObjManager.Find<TEntity>
.Where(Linq['Active'] = True).List;
// Getting Blobs:
hBlobs := ObjManager.Find<TEntity>
.Select(TProjections.ProjectionList
.Add(Linq['Id'])
.Add(Linq['BlobField'])
.Where((Linq['Active'] = True)
and (Linq['BlobField'].IsNotNull)).ListValues;
for hBlob in hBlobs do
begin
hEntity := ObjManager.Find<TEntity>(hBlob.Values[0]); // this uses the ObjManagers cache, so no SQL is fired...
hEntity.BlobField:= hBlob.Values[1];
end;
but this needs 2 selects and I have to check hEntity.BlobField.Available every time I want to only get the loaded Blobs...
