how i write this sql query to linq query - linq-to-sql

Question

i just want to use LinqToSql classes query. here i just want to convert this sql query to appropriate linq query.
this is my sql query:
SELECT j.[JobID], p.[PreparedEmailID],
p.[Name] AS 'PreparedEmailName',
j.[CreatedOn], j.[CompletedOn],
j.[SubscriberCount], j.[EmailsSent],
(SELECT TOP 1 [Message] FROM
[LoggedMessages] WHERE [JobID] =
j.[JobID] ORDER BY [LoggedMessageID] DESC)
AS 'LoggedMessage' FROM [Jobs] AS j
INNER JOIN [PreparedEmails] AS p
ON p.[PreparedEmailID] =
j.[PreparedEmailID]
and my generated linq query is like:
var query = from j in db.Jobs
join p in db.PreparedEmails on j.PreparedEmailID equals p.PreparedEmailID
join l in db.LoggedMessages on j.JobID equals l.JobID into ej
from l in ej.DefaultIfEmpty() orderby l.LoggedMessageID descending
orderby l.LoggedMessageID descending
orderby j.CreatedOn descending
select new
{
JobID = j.JobID,
PreparedEmailID = p.PreparedEmailID,
PreparedEmailName = p.Name,
CreatedOn = j.CreatedOn,
CompletedOn = j.CompletedOn,
SubscriberCount = j.SubscriberCount,
EmailsSent = j.EmailsSent,
LoggedMsg = l.Message
};

Answer 1

I prepared some linQ query for you (but i didn't test it in VS because i have no access to it now, so please be careful because it can contain some errors):
var list = from Jobs
join PreparedEmails on Jobs.PreparedEmailID == PreparedEmails.PreparedEmailID
join LoggedMessages on LoggedMessages.JobID == Jobs.JobID
select
{
JobID = Jobs.JobID,
PreparedEmailID = PreparedEmails.PreparedEmailID,
PreparedEmailName = PreparedEmails.Name,
CreatedOn= Jobs.CreatedOn,
CompletedOn = Jobs.CompletedOn,
SubscriberCount = Jobs.SubscriberCount,
EmailsSent = Jobs.EmailsSent,
LoggedMessage = LoggedMessages.Message
} orderby descending LoggedMessages.LoggedMessageID;
It should help a little bit ...

Answer 2

this is solution:
var query = from j in db.Jobs
join p in db.PreparedEmails on j.PreparedEmailID equals p.PreparedEmailID
orderby j.CreatedOn descending
select new
{
JobID = j.JobID,
PreparedEmailID = p.PreparedEmailID,
PreparedEmailName = p.Name,
CreatedOn = j.CreatedOn,
CompletedOn = j.CompletedOn,
SubscriberCount = j.SubscriberCount,
EmailsSent = j.EmailsSent,
LoggedMsg = (from l in db.LoggedMessages
where j.JobID == l.JobID
orderby l.LoggedMessageID descending
select l.Message).FirstOrDefault()
};
