I am trying to get the same results as with a SQL query using Entity Framework method syntax.
SQL query :
select
mr.*, mrf.userId as RequesterUserId, mrt.UserId as ReceiverUserId
from
MoneyRequests mr
inner join
MoneyReqFrom mrf on mr.MoneyRequestId = mrf.MoneyRequestId
inner join
MoneyReqTo mrt on mr.MoneyRequestId = mrt.MoneyRequestId
where
mr.MoneyRequestId = 'acfc8008-4cf7-47ec-a3fe-0fe245af77cc'
EF Linq method syntax :
var moneyreqResponse = context.MoneyRequests
.Join(context.MoneyReqFroms,
mr => mr.MoneyRequestId,
mrf => mrf.MoneyRequestId,
(mr, mrf) => new
{
MoneyRequestId = mr.MoneyRequestId,
Amount = mr.Amount,
RequestType = mr.RequestType,
CreationDate = mr.CreationDate,
RequesterUserId = mrf.UserId
})
.Join(context.MoneyReqTos,
mr => mr.MoneyRequestId,
mrt => mrt.MoneyRequestId,
(mr, mrt) => new
{
MoneyRequestId = mr.MoneyRequestId,
Amount = mr.Amount,
RequestType = mr.RequestType,
CreationDate = mr.CreationDate,
ReceiverUserId = mrt.UserId,
Email = mrt.Email
})
.Where(fullEntry => fullEntry.MoneyRequestId == "acfc8008-4cf7-47ec-a3fe-0fe245af77cc")
.ToList();
I retrieve the data from the database except the column RequesterUserId
.
Do you know why?
Thanks
Your query returns a MoneyRequests
type, which I belive does not contain RequesterUserId
.
You should define a new type with all the properties you need (those returned by the join) and add it to your DbContext.
Also probably you want to mark your new type as keyless
