I have the following linq query and it is giving the following error: A query body must end with a select clause or a group clause
from sdc in ScheduleDestinationCaches
let twins = from gt in GetTwins(72)
join ssFilter in ScheduleStops on sdc.CarrierID equals ssFilter.CarrierID
join ssLookup in ScheduleStops on sdc.CityID equals ssLookup.CityID
join sc in ScheduleCarriers on ssLookup.CarrierID equals sc.CarrierID
where twins.Contains(ssFilter.StopID ) || ssFilter.StopID == 72
select sc
any ideas?
By the way I'm using linqpad
Let's add some indentation:
from sdc in ScheduleDestinationCaches
let twins = from gt in GetTwins(72)
join ssFilter in ScheduleStops on sdc.CarrierID equals ssFilter.CarrierID
join ssLookup in ScheduleStops on sdc.CityID equals ssLookup.CityID
join sc in ScheduleCarriers on ssLookup.CarrierID equals sc.CarrierID
where twins.Contains(ssFilter.StopID ) || ssFilter.StopID == 72
select sc
Can you see the issue now? Adding from as an assignment to let-defined variable starts new LINQ expression, which end with select sc. This makes the outer query not to have select clause at all!
I think you're looking for
from sdc in ScheduleDestinationCaches
let twins = GetTwins(72)
join ssFilter in ScheduleStops on sdc.CarrierID equals ssFilter.CarrierID
join ssLookup in ScheduleStops on sdc.CityID equals ssLookup.CityID
join sc in ScheduleCarriers on ssLookup.CarrierID equals sc.CarrierID
where twins.Contains(ssFilter.StopID ) || ssFilter.StopID == 72
select sc
Comments-based update
from sdc in ScheduleDestinationCaches
let twins = GetTwins(72).Select(x => x.Id)
join ssFilter in ScheduleStops on sdc.CarrierID equals ssFilter.CarrierID
join ssLookup in ScheduleStops on sdc.CityID equals ssLookup.CityID
join sc in ScheduleCarriers on ssLookup.CarrierID equals sc.CarrierID
where twins.Contains(ssFilter.StopID ) || ssFilter.StopID == 72
select sc

can someone please help me in combining these 2 Teradata queries into a single query? The tables - cdb.dim_party_doc_id, cdb.dim_doc_issuer, mdb.fp_account_entity_map do not have customer_account_number in them, so I not able to directly join all these tables in a single query directly.
Thanks a lot!!

I'm trying to build a linq query based on this:
select
SERVICE_REQUEST_CR.SRCR_FK_SR, SERVICE_REQUEST.SR_TX_NAME,
AC_USER.USER_TX_NAME, SERVICE_REQUEST_CR.SRCR_DT_CREATED,
SERVICE_REQUEST_CR_STATUS.SRCRST_TX_DESCRIPTION,
COUNT(SERVICE_REQUEST_PROGRAM.SRPG_FK_SR_ID) as Activities
from
SERVICE_REQUEST_CR
inner join
AC_USER on AC_USER.USER_ID = SERVICE_REQUEST_CR.SRCR_FK_REQUESTOR
inner join
SERVICE_REQUEST_CR_STATUS on SERVICE_REQUEST_CR_STATUS.SRCRST_ID = SERVICE_REQUEST_CR.SRCR_FK_CR_STATUS
inner join
SERVICE_REQUEST on SERVICE_REQUEST.SR_ID = SERVICE_REQUEST_CR.SRCR_FK_SR
inner join
SERVICE_REQUEST_PROGRAM on SERVICE_REQUEST_PROGRAM.SRPG_FK_SR_ID = SERVICE_REQUEST_CR.SRCR_FK_SR
group by

AC_USER.USER_TX_NAME, SERVICE_REQUEST_CR.SRCR_DT_CREATED,
SERVICE_REQUEST_CR_STATUS.SRCRST_TX_DESCRIPTION,
SERVICE_REQUEST_PROGRAM.SRPG_FK_SR_ID
This is as far as I could come up with:
Dim x = From cr In db.SERVICE_REQUEST_CR
Join usr In db.AC_USER On usr.USER_ID Equals cr.SRCR_FK_REQUESTOR
Join crSt In db.SERVICE_REQUEST_CR_STATUS On crSt.SRCRST_ID Equals cr.SRCR_FK_CR_STATUS
Join sr In db.SERVICE_REQUEST On sr.SR_ID Equals cr.SRCR_FK_SR
Join srProg In db.SERVICE_REQUEST_PROGRAM On srProg.SRPG_FK_SR_ID Equals cr.SRCR_FK_SR
Could anyone give me a help with this? It's the grouping that gets confusing so I just put the joins and the query to keep it simple.
Thanks,
Something like this, but I am not sure about Basic syntax:
Dim x = From cr In db.SERVICE_REQUEST_CR
Join usr In db.AC_USER On usr.USER_ID Equals cr.SRCR_FK_REQUESTOR
Join crSt In db.SERVICE_REQUEST_CR_STATUS On crSt.SRCRST_ID Equals cr.SRCR_FK_CR_STATUS
Join sr In db.SERVICE_REQUEST On sr.SR_ID Equals cr.SRCR_FK_SR
Join srProg In db.SERVICE_REQUEST_PROGRAM On srProg.SRPG_FK_SR_ID Equals cr.SRCR_FK_SR
group new
{
cr.SRCR_FK_SR,
sr.SR_TX_NAME,
usr.USER_TX_NAME,
cr.SRCR_DT_CREATED,
crSt.SRCRST_TX_DESCRIPTION,
srProg.SRPG_FK_SR_ID
}
by new
{
cr.SRCR_FK_SR,
sr.SR_TX_NAME,
usr.USER_TX_NAME,
cr.SRCR_DT_CREATED,
crSt.SRCRST_TX_DESCRIPTION,
srProg.SRPG_FK_SR_ID
} into gr
select new
{
gr.Key.SRCR_FK_SR,
gr.Key.SR_TX_NAME,
gr.Key.USER_TX_NAME,
gr.Key.SRCR_DT_CREATED,
gr.Key.SRCRST_TX_DESCRIPTION,
gr.Key.SRPG_FK_SR_ID,
Activities = gr.Count()
}
I am unable to execute the below linq.
var items( from p in Patients
join q in MURWorksheets on p.PatientId equals q.PatientId into step1
from s in step1.DefaultIfEmpty()
join t in MURWorksheetAnswers on s.MURWorksheetId equals t.MURWorksheetId into step2
from s2 in step2.DefaultIfEmpty()
select new {p.FirstName , Date = (s.MURDate == null ? DateTime.Now.Date : s.MURDate),
s2.MURQuestionnaireId,s2.MURExpctedAnswersId}).ToList();
Here is the sql for the same for your reference.
select a.FirstName,b.MURDate,c.MURQuestionnaireId,c.MURWorksheetAnswersID from Patients as a
left join MURWorksheet as b on a.PatientId = b.PatientId
left join MURWorksheetAnswers as c on b.MURWorksheetId = c.MURWorksheetId
You are missing an equals sign in your pasted code:
var items = (from p in Patients
join q in MURWorksheets on p.PatientId equals q.PatientId into step1
from s in step1.DefaultIfEmpty()
join t in MURWorksheetAnswers on s.MURWorksheetId equals t.MURWorksheetId into step2
from s2 in step2.DefaultIfEmpty()
select new {p.FirstName , Date = (s.MURDate == null ? DateTime.Now.Date : s.MURDate),
s2.MURQuestionnaireId,s2.MURExpctedAnswersId}).ToList();
I have this Model
My goal is to retrieve all resources for a user except for resources that share a restricted role with that user.
This is not too hard in straight SQL (6BA60C09-2873-46A5-BAFB-5996A6C6482B is the userid)
SELECT distinct r.Name
FROM dbo.Resources xr
INNER JOIN [dbo].[x_Resource_RestrictedRole] rr ON xr.Id = rr.ResourceId
INNER JOIN [dbo].[aspnet_UsersInRoles] ur ON ur.RoleId = rr.RoleId
AND ur.UserId = '6BA60C09-2873-46A5-BAFB-5996A6C6482B'
RIGHT JOIN dbo.Resources r on r.id = xr.id
WHERE xr.id IS NULL
I can't figure out a good strategy for this in EF because I don't have access to the association tables.
Can this be done in LINQ or lambda expression?
You have some sort of question but I will try to answer about your query
var y = (from xr in context.Resources
join rr in context.x_Resource_RestrictedRole on xr.Id equals rr.ResourceId
join ur in context.aspnet_UsersInRoles on rr.RoleId equals ur.RoleId
join r in context.Resources on xr.id equals r.id into rJoin
from r2 in rJoin.DefaultIfEmpty()
where xr.id == null && ur.UserId = "6BA60C09-2873-46A5-BAFB-5996A6C6482B"
select new { r.Name }).Distinct(c => c.Name).ToList();
I have a query which have multiple conditions on on clause
SELECT *
FROM
CATALOGITEM with (nolock) INNER JOIN CATALOG with (nolock) ON
CATALOGITEM.catalog_id = CATALOG.catalog_id and not(catalog.catalog_id = 21) AND NOT(catalog.catalog_id = 20)
INNER JOIN PRODUCT with (nolock) ON
CATALOGITEM.s_num = PRODUCT .s_num
LEFT OUTER JOIN PRODUCT_DETAIL with (nolock) ON
PRODUCT_DETAIL.s_num = PRODUCT.s_num
WHERE
(
CATALOGITEM.publish_code = 'upd' OR
CATALOG_ITEM.publish_code = 'ins' OR
PRODUCT.publish_code = 'upd' OR
PRODUCT.publish_code = 'ins'
)
and
(CATALOG.unit_id = bu.unit_id)
How to write this in LINQ.
Please advice.
Assume you're missing a join to PRODUCT table?
Anyway, this should get you started.
var query = (from ci in db.catalogitem
join c in db.catalog on ci.catalog_id equals c.catalog_id
join p in db.products on ci.s_num equals p.s_num
join pd in db.productdetail on p.s_num equals pd.s_num into tempprods
from prods in tempprods.DefaultIfEmpty()
where !(c.catalog_id.Contains(21, 20))
&& (ci.publish_code.Contains('upd','ins')) ||
(p.publish_code.Contains('upd','ins'))
select ci)
If you want to preserve the (NOLOCK) hints, I have blogged a handy solution using extension methods in C#. Note that this is the same as adding nolock hints to every table in the query.
