I have a query according to the :
SELECT
tblDefinition.TopsisType, tblTemplate.tType, tblEvaluationFormCategory.Title AS EvaluationCategory,
CASE tType WHEN 1 THEN N'2'
ELSE N'1' END ProcessType,
tblDefinition.Description, tblDefinition.TemplateID, 1 Destinition
FROM tblTemplate INNER JOIN
tblEvaluationFormCategory ON tblTemplate.CategoryID = tblEvaluationFormCategory.ID INNER JOIN
tblEFQMAlternative INNER JOIN
tblDefinition ON ([tblEFQMAlternative].[TopsisID] = [tblDefinition].[TopsisID] AND [tblEFQMAlternative].[CustomerID] = [tblDefinition].[CustomerID]) INNER JOIN
tblGroupMembers ON ([tblDefinition].[TopsisID] = [tblGroupMembers].[TopsisID]
AND tblDefinition.CustomerID =
tblGroupMembers.CustomerID) ON tblTemplate.TemplateID = tblDefinition.TemplateID
INNER JOIN
tblTerm ON tblDefinition.TermGrant = tblTerm.Title
WHERE (tblTerm.ID = 20) AND (tblGroupMembers.UserID = 558)
GROUP BY tblDefinition.TopsisType, tblTemplate.tType, tblEvaluationFormCategory.Title,
tblDefinition.Description, tblDefinition.TemplateID
when i convert to linq, then error to :
Field [([tblDefinition].[TopsisID] = [tblGroupMembers]].[[TopsisID] AND tblDefinition.CustomerID = tblGroupMembers.CustomerID) ON tblTemplate.TemplateID] not found in the current Data Context.
What should I do?
I have to change a query, and want to add some pre-defined results (outputs) to the query when two values are found on two different columns.
Basically I want to add values to a new column on a query. I tried to use CASE but no luck until now.

I temp table on a query will work?
Thanks
I wrote a query that does an inner join of two subqueries. The first subquery has an alias of "SRC" and the other has an alias of "DEST". What I want to do is update some fields in the table NomineeActionLegislatorVoteDetail (part of DEST subquery) with values from the table Nominee_Committee_Vote (part of SRC subquery). It souds easy but I just cannot figure out how to do it. Does anyone have any suggestions? Any help would be appreciated.
Here is the query I wrote:
select *
from (
select ncv.*,
na.NomineeActionId,
l.LegislatorId
from ongoing..Nominee_Committee_Vote ncv
inner join azleg..NomineeAction na on
ncv.session_id = na.x_session_id and
ncv.committee_id = na.x_committee_id and
ncv.agency_id = na.x_agency_id and
ncv.position_id = na.x_position_id and
ncv.nominee_id = na.x_nominee_id and
ncv.received_date = na.x_received_date
inner join status..session s on
ncv.session_id = s.session_id
inner join azleg..Legislator l on
ncv.member_id = l.x_member_id and
s.legislature = l.LegislatureId
) SRC
inner join (
select votedetail.*
from azleg..NomineeActionLegislatorVoteDetail votedetail
inner join azleg..NomineeAction nom_action on
votedetail.NomineeActionId = nom_action.NomineeActionId
) DEST on
SRC.agency_id = DEST.x_agency_id and
SRC.position_id = DEST.x_position_id and
SRC.nominee_id = DEST.x_nominee_id and
SRC.received_date = DEST.x_received_date and
SRC.session_id = DEST.x_session_id and
SRC.committee_id = DEST.x_committee_id and
SRC.member_id = DEST.x_member_id
where SRC.NomineeActionId <> DEST.NomineeActionId
OR SRC.LegislatorId <> DEST.LegislatorId
OR SRC.Vote <> DEST.Vote
Can you insert the update in front of the sub queries
UPDATE NomineeActionLegislatorVoteDetail
SET NomineeActionLegislatorVoteDetail.COLUMNNAME = src.VALUE
--SubQueriesBelow
from
(select ncv.*, na.NomineeActionId, l.LegislatorId from ongoing..Nominee_Committee_Vote ncv
inner join azleg..NomineeAction na on
ncv.session_id = na.x_session_id and
ncv.committee_id = na.x_committee_id and
ncv.agency_id = na.x_agency_id and
ncv.position_id = na.x_position_id and
ncv.nominee_id = na.x_nominee_id and
ncv.received_date = na.x_received_date
inner join status..session s on
ncv.session_id = s.session_id
inner join azleg..Legislator l on
ncv.member_id = l.x_member_id and
s.legislature = l.LegislatureId) SRC
inner join
(select votedetail.* from azleg..NomineeActionLegislatorVoteDetail votedetail
inner join azleg..NomineeAction nom_action on
votedetail.NomineeActionId = nom_action.NomineeActionId) DEST on
SRC.agency_id = DEST.x_agency_id and
SRC.position_id = DEST.x_position_id and
SRC.nominee_id = DEST.x_nominee_id and
SRC.received_date = DEST.x_received_date and
SRC.session_id = DEST.x_session_id and
SRC.committee_id = DEST.x_committee_id and
SRC.member_id = DEST.x_member_id
where SRC.NomineeActionId <> DEST.NomineeActionId
OR SRC.LegislatorId <> DEST.LegislatorId
OR SRC.Vote <> DEST.Vote
It looks like the update is on a table in the sub query so it could be re factored to have one subquery
I've adjusted the lay-out of your query a bit to disclose better where subqueries start and end. In your DEST subquery, you join NomineeAction but you don't select any columns from it, so it only filters rows from NomineeActionLegislatorVoteDetail for which no NomineeAction exists. So really you wanna be updating and joining on columns from NomineeActionLegislatorVoteDetail exclusively. Based on that, I would write the update query like so:
update votedetail set
votedetail.SomeColumn = SomeValue,
votedetail.SomeOtherColumn = SomeOtherValue
from azleg..NomineeActionLegislatorVoteDetail votedetail
join azleg..NomineeAction nom_action on
votedetail.NomineeActionId = nom_action.NomineeActionId
join (
select ncv.*,
na.NomineeActionId,
l.LegislatorId
from ongoing..Nominee_Committee_Vote ncv
inner join azleg..NomineeAction na on
ncv.session_id = na.x_session_id and
ncv.committee_id = na.x_committee_id and
ncv.agency_id = na.x_agency_id and
ncv.position_id = na.x_position_id and
ncv.nominee_id = na.x_nominee_id and
ncv.received_date = na.x_received_date
inner join status..session s on
ncv.session_id = s.session_id
inner join azleg..Legislator l on
ncv.member_id = l.x_member_id and
s.legislature = l.LegislatureId
) SRC on
SRC.agency_id = votedetail.x_agency_id and
SRC.position_id = votedetail.x_position_id and
SRC.nominee_id = votedetail.x_nominee_id and
SRC.received_date = votedetail.x_received_date and
SRC.session_id = votedetail.x_session_id and
SRC.committee_id = votedetail.x_committee_id and
SRC.member_id = votedetail.x_member_id
where SRC.NomineeActionId <> votedetail.NomineeActionId
OR SRC.LegislatorId <> votedetail.LegislatorId
OR SRC.Vote <> votedetail.Vote

Try to use the right UPDATE SELECT Syntaxe.
If you look at the code I did, I had to change a bit your query to do the joins. See if it fits to you.

So here is the problem:
the 'should be' PK is a 1 varchar 3 int's key. for every key there is supposed to be 1 row in each of the tables which you can see in the image. the 'parent' of those keys is the table Instellingen. This table is generated with a distinct select of InstellingenLogin
the real problem is that there are about 10 doubles in InstellingenLogin (of about 5k records) and because of this, some rows return double in the view, with only the columns of InstellingLogin different.
what i want is that if there are 2 or more rows in InstellingLogin with the same key, that only 1 will show (the first one,... doenst matter which one, just 1 will do).
in short that means that for every record in Instellingen i want 1 record in this view.
is there any way to do that?
I'm a bit confused but I think the answer below should illustrate how to acheive what you need:
SELECT * FROM Instellingen as i
CROSS APPLY
(
SELECT TOP (1) * FROM InstellingLogin as il
WHERE i.INST_LOC_REF = il.Inst_Loc_REF
and i.INST_LOCNR=il.Inst_Loc_Nr
and i.INST_REF=il.Inst_InstellingIKON_REF
and i.INST_TYPE=il.Inst_InstellingIKONType
order by il.Datum_tot
) la
This will basically join on Instellingen and InstellingenLogin but only on the first record found
You can use DENSE_RANK to Arbitrarily select a row. Basically create a CTE that ranks the instellinglogin and then only select the one with a Rank of 1. The tricky bit is that you have a left join to instellinglogin so you'll need to do the inner join inside the left join like so. Also I kept the Join condition as the the columns to partition. This may not be correct.

You need to wrap InstellingenLogin in some kind of aggregate to remove the duplicates and then join to the result - you can do this with a subquery. You could do a GROUP BY with MIN() or MAX() to pick a value or you could do ROW_NUMBER() OVER (ORDER BY some_criteria PARTIION BY your_key) and pick the first row.
Also, I recommend using aliases on your tables - makes it far more readable
