I have the following LINQ-to-SQL code
var customerList = from cm in dc.ConsignmentMarginBreakdowns
join tm in dc.ConsignmentTripBreakdowns on new { Depot = cm.Depot, TripNumber = cm.TripNumber, TripDate = cm.TripDate } equals new { Depot = tm.Depot, TripNumber = tm.TripNumber, TripDate = tm.TripDate }
join sl in dc.SageAccounts on new { LegacyID = cm.Customer, Customer = true } equals new { LegacyID = sl.LegacyID, Customer = sl.Customer }
join ss in dc.SageAccounts on sl.ParentAccount equals ss.ID
where (tm.DeliveryDate >= dateRange1.FromDate && tm.DeliveryDate <= dateRange1.ToDate) || (dateRange2.FromDate != null && (tm.DeliveryDate >= dateRange2.FromDate && tm.DeliveryDate <= dateRange2.ToDate))
where tm.Depot == depotLetter
group cm by new { ss.Name, ss.ID } into cmg
select new
{
CustomerID = cmg.Key.ID,
CustomerName = cmg.Key.Name,
Sales1 = cmg.Where(a => a.DeliveryDate >= dateRange1.FromDate && a.DeliveryDate <= dateRange1.ToDate).Sum(a => a.TripSalesTotal),
Sales2 = dateRange2.FromDate != null ? tmg.Where(a => a.DeliveryDate >= dateRange2.FromDate && a.DeliveryDate <= dateRange2.ToDate).Sum(a => a.TripSalesTotal) : 0.00m
};
The problem I have is that the 'DeliveryDate' from 'tm' is not in the scope of the query when I select. Any ideas how I can get this value in my query?
Thanks
Just create another anonymous type
group new { cm, tm } by new { ss.Name, ss.ID } into cmg
so your query would look like this:
var customerList = from cm in dc.ConsignmentMarginBreakdowns
join tm in dc.ConsignmentTripBreakdowns on new { Depot = cm.Depot, TripNumber = cm.TripNumber, TripDate = cm.TripDate } equals new { Depot = tm.Depot, TripNumber = tm.TripNumber, TripDate = tm.TripDate }
join sl in dc.SageAccounts on new { LegacyID = cm.Customer, Customer = true } equals new { LegacyID = sl.LegacyID, Customer = sl.Customer }
join ss in dc.SageAccounts on sl.ParentAccount equals ss.ID
where (tm.DeliveryDate >= dateRange1.FromDate && tm.DeliveryDate <= dateRange1.ToDate) || (dateRange2.FromDate != null && (tm.DeliveryDate >= dateRange2.FromDate && tm.DeliveryDate <= dateRange2.ToDate))
where tm.Depot == depotLetter
group new { cm, tm } by new { ss.Name, ss.ID } into cmg
select new
{
CustomerID = cmg.Key.ID,
CustomerName = cmg.Key.Name,
Sales1 = cmg.Where(a => a.tm.DeliveryDate >= dateRange1.FromDate && a.tm.DeliveryDate <= dateRange1.ToDate).Sum(a => a.cm.TripSalesTotal),
Sales2 = dateRange2.FromDate != null ? tmg.Where(a => a.tm.DeliveryDate >= dateRange2.FromDate && a.tm.DeliveryDate <= dateRange2.ToDate).Sum(a => a.cm.TripSalesTotal) : 0.00m
};

I want to assign GetMajorMileStone(projecttask.ProjectTaskId) result to MajorMilestone.
I tried but getting following error:
LINQ to Entities does not recognize the method

I separate multiple simple query for testing. Please try to execute below two query and check whether successful or not.
// First query to get project
var query1 = from project in db.Project.Where(t => (t.Active || t.TempActive) && t.ProjectId == projectid)
join UP in db.User_X_Project on project.ProjectId equals UP.ProjectId
where (UP.UserId == userId && UP.Active)
orderby (project.Priority ?? int.MaxValue)
orderby (project.ProjectTitle)
.Select new { project = project }.ToList();
// Second query to get projecttask from query1.project and execute store procedure
var query2 = from projecttask in query1.project.ProjectTask.Where(t => t.Active && (
(includeArchived == true && t.TaskStatusId == (int?)TaskStatus.Archived) ||
(includeArchived == false && t.TaskStatusId != (int?)TaskStatus.Archived)) ||
t.TaskStatusId != (int?)TaskStatus.Planned)
join schedule in query1.project.ProjectTask.SelectMany(p => p.ProjectTaskSchedule) on projecttask.ProjectTaskId equals schedule.ProjectTaskId
join daily in db.ProjectTaskSchedule.SelectMany(p => p.DailyStatus) on schedule.ProjectTaskScheduleId equals daily.ProjectTaskScheduleId
where schedule.Active && daily.Active && projecttask.Active && schedule.ResourceId == userId && (
(EntityFunctions.TruncateTime(daily.Date) >= EntityFunctions.TruncateTime(startDate.Date) &&
EntityFunctions.TruncateTime(daily.Date) <= EntityFunctions.TruncateTime(endDate.Date))
)
orderby schedule.StartDate
.Select new
{
MajorMilestone = db.GetMajorMileStone(projecttask.ProjectTaskId).FirstOrDefault(),
}.ToList();
Let me know it has result or not. In the meantime you can check this "Method cannot be translated into a store expression"
It has link to article about what not to do with linq. Nested Linq like this is best to avoid and better to split up the query. If it affects the execution time, it better to execute raw sql.

how to write multiple left joins in linq.. the below linq query i am writing based on this sp

I dont know the exact relation between the table but, i have assumed and written query. hope it helps u
I have a list with a column value like "0000000385242160714132019116002239344.ACK" i need to take last 6 digits from this value like "239344" without extension(.ack) when binding to the list.
And i need to find the sum of Salary field also.
My query looks like below.
var result = from p in Context.A
join e in B on p.Id equals e.Id
join j in Context.C on e.CId equals j.CId
where (e.Date >= periodFrom && e.Date <= periodTo)
group new
{
e,
j
} by new
{
j.J_Id,
e.Date,
e.Es_Id,
e.FileName,
j.Name,
e.ACK_FileName,
p.EmpSalaryId,
p.Salary
} into g
orderby g.Key.CId, g.Key.Es_Id, g.Key.Date, g.Key.FileName
select new
{
CorporateId = g.Key.CId,
ProcessedDate = g.Key.Date,
EstID = g.Key.Es_Id,
FileName = g.Key.FileName,
Name = g.Key.Name,
ack = g.Key.ACK_FileName,
EmpSalaryId = g.Key.EmpSalaryId,
Salary=g.Key.Salary
};
var Abc=result.ToList();
var result = (from p in Context.A
join e in B on p.Id equals e.Id
join j in Context.C on e.CId equals j.CId
where (e.Date >= periodFrom && e.Date <= periodTo)
group new { e, j } by new
{
j.J_Id,
e.Date,
e.Es_Id,
e.FileName,
j.Name,
ACK_FileName = e.ACK_FileName.Substring(e.ACK_FileName.IndexOf(".ACK") - 7, 11),
p.EmpSalaryId,
p.Salary
} into g
orderby g.Key.CId, g.Key.Es_Id, g.Key.Date, g.Key.FileName
select new
{
CorporateId = g.Key.CId,
ProcessedDate = g.Key.Date,
EstID = g.Key.Es_Id,

First I want to say hello, I'm new to this site ;-)
My problem is to transform the following sql-query into a c# linq-query.
( I HAVE searched hard for an existing answer but I'm not able to combine the solution for
the joins on multiple conditions and the grouping / counting ! )
The sql-query :
DECLARE #datestart AS DATETIME
DECLARE #dateend AS DATETIME
SET #datestart = '01.04.2014'
SET #dateend = '30.04.2014'
SELECT md1.value AS [controller],md2.value AS [action], COUNT(md2.value) AS [accesscount], MAX(re.TIMESTAMP) AS [lastaccess] FROM recorderentries AS re
INNER JOIN messagedataentries AS md1 ON re.ID = md1.recorderentry_id AND md1.position = 0
INNER JOIN messagedataentries AS md2 ON re.ID = md2.recorderentry_id AND md2.position = 1
WHERE re.TIMESTAMP >= #datestart AND re.TIMESTAMP <= #dateend
AND re.messageid IN ('ID-01','ID-02' )
GROUP BY md1.value,md2.value
ORDER BY [accesscount] DESC
Any suggestions are welcome ...
What i have so far is this :
var _RecorderActionCalls = (from r in _DBContext.RecorderEntries
join m1 in _DBContext.MessageDataEntries on
new {
a = r.ID,
b = 0
} equals new {
a = m1.ID,
b = m1.Position
}
join m2 in _DBContext.MessageDataEntries on
new {
a = r.ID,
b = 0
} equals new {
a = m2.ID,
b = m2.Position
}
where r.TimeStamp >= StartDate & r.TimeStamp <= EndDate & (r.MessageID == "VAREC_100_01" | r.MessageID == "VAAUTH-100.01")
group r by new { md1 = m1.Value, md2 = m2.Value } into r1
select new { controller = r1.Key.md1, action = r1.Key.md2, count = r1.Key.md2.Count() }).ToList();
But this throws an exception ( translated from german ) :
DbExpressionBinding requires an input expression with a Listing Result Type ...
UPDATE : Back with headache ... ;-)
I found a solution to my problem :
var _RecorderActionCalls = _DBContext.RecorderEntries
.Where(r => r.TimeStamp >= StartDate & r.TimeStamp <= EndDate & (r.MessageID == "VAREC_100_01" | r.MessageID == "VAAUTH-100.01"))
.GroupBy(g => new { key1 = g.MessageData.FirstOrDefault(md1 => md1.Position == 0).Value, key2 = g.MessageData.FirstOrDefault(md2 => md2.Position == 1).Value })
.Select(s => new {
ControllerAction = s.Key.key1 + " - " + s.Key.key2,
Value = s.Count(),
Last = s.Max(d => d.TimeStamp)
}).ToList();
With this syntax it works for me. Thank you for thinking for me :-)
Something like that:
List<string> messageIdList = new List<string> { "ID-01", "ID-02" };
from re in RecorderEntries
from md1 in MessageDataEntries
from md2 in MessageDataEntries
where re.ID = md1.recorderEntry_id && md1.position == 0
where re.ID = md2.recorderEntry_id && md2.position == 1
where idList.Contains(re.messageid)
let joined = new { re, md1, md2 }
group joined by new { controller = joined.md1.value, action = joined.md2.value } into grouped
select new {
controller = grouped.Key.controller,
action = grouped.Key.action,
accesscount = grouped.Where(x => x.md2.value != null).Count(),
lastaccess = grouped.Max(x => x.re.TimeStamp) }
Hello I have a C# lambda expression looks like it should work to me but its returning nothing.
CategoryItems = (db.Items.Include("Pictures").Join(db.Rentals,

PricePerDay = i.Rental.RentalPrice ?? 0.00m,
ItemID = i.Item.itemID,

})).ToPagedList(page, 5);
Any help appreciated
var CategoryItems =
