I am joining couple tables and trying to get the count of each status.
EmployeeEvaluationsStatuses
has the following fields :
Id, Title.
Data in EmployeeEvaluationsStatuses
look like :
Id Title
1 New - Incomplete
2 Submitted – All Docs
3 Approved
4 Rejected - Need More Info
5 Qualified
I want to get the result as follows :
StatusCount Status
60 New - Incomplete
42 Submitted – All Docs
20 Qualified
Here is how my query look like :
from ep in EmployeePositions.Where(a => a.CorporateId == 1596)
join ee in EmployeeEvaluations.Where(e => e.TargetGroupId != null) on ep.EmployeeId equals ee.EmployeeId
join ees in EmployeeEvaluationStatuses on ee.EvaluationStatusId equals ees.Id
group ees by ees.Id into g
select new
{
StatusCount = g.Count()
,Status= ees .title
}
I am getting an error " The name 'ees' does not exist in the current context
"
I am not sure about navigational properties.
public partial class WotcEntities : DbContext
{
public WotcEntities()
: base(hr.common.Database.EntitiesConnectionString("res://*/ef.WotcModel.csdl|res://*/ef.WotcModel.ssdl|res://*/ef.WotcModel.msl", "devConnection"))
{
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
throw new UnintentionalCodeFirstException();
}
public virtual DbSet<EmployeeEvaluations> EmployeeEvaluations { get; set; }

}

}
public int Id { get; set; }

You have to use a composite key in your group by
and navigate using g.Key
from ep in EmployeePositions.Where(a => a.CorporateId == 1596)
join ee in EmployeeEvaluations.Where(e => e.TargetGroupId != null) on ep.EmployeeId equals ee.EmployeeId
join ees in EmployeeEvaluationStatuses on ee.EvaluationStatusId equals ees.Id
group ees by new { ees.Id, ees.title } into g
select new
{
StatusCount = g.Count(),
Status= g.Key.title
