I have the following tables:
Project:
Id
SettlementId
...
Settlement
Id
Name
AreaId
Area
Id
Name
...
I need to get all settlements that belong to a particular area (i get the areaId from the selected dropdownlist) that are not part of any project.
So far this is my query:
var settlements = (from s in entities.Settlements
where s.AreaId == selectedAreaId
select s).toList();
Am not entirely sure how to filter out the settlements that are already part of an existing project.
Thanks for your time!
你试过了吗?
where s.Projects.Count() == 0
