Question

I am looking for equivalent of the following for Entity SQL.

from row in Parent_Table
select new{
             Parent_Table.include("child_table").Select("SomeField").Max(),
             row
          }

Whereas this is part of whole query

(how can i create a sub query while the lazy loading is off ?)

as i try

myObjectQuery.Include("Proj_PF_" + state_Year).Select("phisicalImprovement").Max();

phisicalImprovement is a field of Proj_PF_” + state_Year and my query is to an other table

get the fallowing exception

'phisicalImprovement' is not a member of 'Transient.collection[NezaratModel.Proj_PF_58_89(Nullable=True,DefaultValue=)]'. To extract a property of a collection element, use a subquery to iterate over the collection. Near simple identifier

Thank you.

There is no equivalent in ESQL and it should not be needed because when you call ESQL you are using ObjectQuery<> so you just pass your ESQL command to the ObjectQuery instance and should be able to call Include for it:

var query = (new ObjectQuery<YourEntity>("SELECT VALUE ...")).Include("SomerRelation");
