Here is my SQL-Query that I want to convert to LINQ:
SELECT artikel.id, charge.id
from Lots charge
JOIN Product artikel on charge.artikel = artikel.id
JOIN StorageQuantity_TAB lmengeTAB on charge.id = lmengeTAB.charge
JOIN StorageQuantity lmenge on lmengeTAB.id = lmenge.id
GROUP BY artikel.id, charge.id
That´s what I got so far:
var query = (from charge in Lots
join artikel in PartProducts on charge.Artikel equals artikel.Id
join lmengeTAB in StorageQuantity_TABs on charge.Id equals lmengeTAB.Charge
join lmenge in StorageQuantities on lmengeTAB.Id equals lmenge.Id
select new
{
artikel.Id,
chargeID = charge.Id,
}).ToList();
So how do I include that GROUP BY statement?

I have a linq to sql statement where I am doing join with a bunch of tables , but I need to left join a table as we are not sure if there be any associated records.
We are left joing as we are not sure if every purchase will have a file associated.
Purchase Join - Invc
Purchase Join - FileStore FileStore##Entity
select * from Purchase p
join Invc i on i.Invc_ID = p.Invc_ID
left join FileStore##Entity fe on p.Purchase_ID = fe.Entity_ID
left join FileStore fs on fs.FileStore_ID = fe.FileStore_ID
where p.Purchase_ID = 53
My current linq to sql works for the regular join , how can I left join the file store and store entity table
PurchaseEntity purchase = (from p in TransactionalDbContext.Purchase
join i in TransactionalDbContext.Invc
on p.InvcId equals i.InvcId
where d.Purchase_Id == id
select new DisputeEntity
{
Purchase_Id = p.Purchase_Id,
InvcId = i.InvcId,
SubmittedDate = d.SubmitDt,
InvcNum = i.InvcNum
// get the file elements by left join file
}).FirstOrDefault();
You can easily perform left or right joins by playing with the DefaultIfEmpy method.
Following your example:
from p in dbContext.Purchases
join i in dbContext.Invc on p.InvcId equals i.InvcId
join fe in dbContext.FileStoreEntities.DefaultIfEmpty() on p.Purchase_ID equals fe.Entity_ID
join fs in dbContext.FileStores.DefaultIfEmpty() on fe.FileStore_ID equals fs.FileStore_ID
I am currently having problems trying the run a query for some tables.
Below is what I am trying to do, I just can't seem to get it to work.
I have also duplicated constituent and gifts to show you the relations between soft credit and gifts/constituents
Link to Table Relations Image
SELECT
Constituent.lookup_id,
Constituent.name,
SplitGifts.amount,
SplitGifts.giftaidamount
FROM
dbo.Gifts Gifts
INNER JOIN dbo.Constituent Constituent
ON Constituent.id = Gifts.constituent_id
INNER JOIN dbo.SplitGifts SplitGifts
ON SplitGifts.giftid = Gifts.id
LEFT JOIN dbo.SoftCredit SoftCredit
ON SoftCredit.giftid = Gifts.id
INNER JOIN dbo.Constituent Constituent_1
ON Constituent_1.id = SoftCredit.constituentid
INNER JOIN dbo.Gifts Gifts_1
ON Gifts_1.id = SoftCredit.giftid
INNER JOIN dbo.Package Package
ON Package.id = SplitGifts.packageid
WHERE
Package.lookup_id = N'CORPCHAL'
Basically, I want the
amount and gift_aid_amount from [SplitGifts]
Constituent Name & lookup_id from [constituent] to show up for all Gifts however if a soft credit exists for that gift I need it to get the same fields via the [SoftCredit] table -> Gifts -> SplitGifts -> Fields
You could try if the query below works.
SELECT
Constituent.lookup_id,
Constituent.name,
SplitGifts.amount,
SplitGifts.giftaidamount
FROM
dbo.Gifts Gifts
LEFT JOIN dbo.SoftCredit SoftCredit ON SoftCredit.giftid = Gifts.id
INNER JOIN dbo.Gifts Gifts_1 ON
Gifts_1.id = SoftCredit.giftid OR
(SoftCredit.giftid IS NULL AND Gifts_1.id = Gifts.id)
INNER JOIN dbo.Constituent Constituent ON
Constituent.id = SoftCredit.constituentid OR
(SoftCredit.constituentid IS NULL AND Constituent.id = Gifts_1.constituent_id)
INNER JOIN dbo.SplitGifts SplitGifts ON SplitGifts.giftid = Gifts_1.id
INNER JOIN dbo.Package Package ON Package.id = SplitGifts.packageid
WHERE
Package.lookup_id = N'CORPCHAL'
It joins back to table Gifts (using alias Gifts_1) on the gift reference in SoftCredit or to itself if there is no SoftCredit.
Table Constituent is joined in a similar fashion: it joins on the value of SoftCredit.constituentid and when NULL, it falls back to Gifts_1.constituent_id.
All next joins regarding the gift should refer to Gifts_1 then.
I have not tested it though. But it might give you a hint in a possible solution direction.
The "Last" function in the query below (line 4 & 5)that I'm using is not exactly what I'm after. The last function finds the last record in that table.
What i need find is the most recent record in the table according to a date field.
SELECT
tblinmate.statusid,
tblinmate.activedate,
Last(tblclassificationhistory.classificationid) AS LastOfclassificationID,
Last(tblsquadhistory.squadid) AS LastOfsquadID,
tblperson.firstname,
tblperson.middlename,
tblperson.lastname,
tblinmate.prisonnumber,
tblinmate.droppeddate,
tblinmate.personid,
tblinmate.inmateid
FROM tblsquad
INNER JOIN (tblperson
INNER JOIN ((tblinmate
INNER JOIN (tblclassification
INNER JOIN tblclassificationhistory
ON tblclassification.classificationid =
tblclassificationhistory.classificationid)
ON tblinmate.inmateid =
tblclassificationhistory.inmateid)
INNER JOIN tblsquadhistory
ON tblinmate.inmateid =
tblsquadhistory.inmateid)
ON tblperson.personid = tblinmate.personid)
ON tblsquad.squadid = tblsquadhistory.squadid
GROUP BY tblinmate.statusid,
tblinmate.activedate,
tblperson.firstname,
tblperson.middlename,
tblperson.lastname,
tblinmate.prisonnumber,
tblinmate.droppeddate,
tblinmate.personid,
tblinmate.inmateid;
This query below does just that, finds the most recent record in a table according to a date field.
my problem is i dont know how to integrate this Query into the above to replace the "Last" function
SELECT a.inmateID,
a.classificationID,
b.max_date
FROM (
SELECT tblClassificationHistory.inmateID,
tblClassificationHistory.classificationID,
tblClassificationHistory.reclassificationDate
FROM tblinmate
INNER JOIN tblClassificationHistory
ON tblinmate.inmateID = tblClassificationHistory.inmateID
) a
INNER JOIN (
SELECT tblClassificationHistory.inmateID,
MAX(tblClassificationHistory.reclassificationDate) as max_date
FROM tblinmate
INNER JOIN tblClassificationHistory
ON tblinmate.inmateID = tblClassificationHistory.inmateID
GROUP BY tblClassificationHistory.inmateID
) b
ON a.inmateID = b.inmateID
AND a.reclassificationDate = b.max_date
ORDER BY a.inmateID;
I got a tip from another forum to combine queries like this
SELECT qryMainTemp.*, qrySquad.*, qryClassification.*
FROM (qryMainTemp INNER JOIN qrySquad ON qryMainTemp.inmateID = qrySquad.inmateID) INNER JOIN qryClassification ON qryMainTemp.inmateID = qryClassification.inmateID;
and it worked :) i separated the first query into the two queries it was made of and then combined the three like shown above.
Sadly this made another problem arise the query is now not up-datable..working on a solution for this
I am trying to get a record by adding values of one column based on key value. Here is the query I have:
SELECT
PM_ProductPayment.ProjectId, SalesDetail.SalesPerson,
PM_ProductCost.ProductCost, dbo.PM_ProductPayment.ProductPayment,
dbo.PM_ProductPayment.PaymentDate
FROM
dbo.PM_ProductPayment
INNER JOIN
dbo.PM_Product ON dbo.PM_ProductPayment.ProjectId = dbo.PM_Product.ProductId
INNER JOIN
dbo.PM_ProductCost ON dbo.PM_ProductPayment.ProductId = dbo.PM_ProductCost.ProductId
INNER JOIN
dbo.SalesDetail ON dbo.PM_Product.SalesPersonId = dbo.SalesDetail.ID
The result I am getting is:
Now, here I want to get single row by adding "Payment" for each product and last payment date.
Please optimize my query or suggest any other better way to do that..
Thanks,
SELECT pay.ProjectId,
sum(pay.ProductPayment),
max(pay.PaymentDate)
FROM dbo.PM_ProductPayment pay
INNER JOIN dbo.PM_Product pro ON pay.ProjectId = pro.ProductId
INNER JOIN dbo.PM_ProductCost cos ON pay.ProductId =cos.ProductId
INNER JOIN dbo.SalesDetail sal ON pro.SalesPersonId = sal.ID
GROUP BY pay.ProjectId
I have the following query:

WK.WKO_WorkOrderTypeCode,
wk.WKO_MatlIssueDate,
Item.IMA_ItemTypeCode,
Item.IMA_OnHandQty
I need 1 record returned for each wk.wko_workorderid. There is a field that is not included that I'm not sure how to get. I need to retrieve the woo.woo_workcenterid that corresponds to min(WO.woo_operationseqID)as seqid. I cannot include it in the general query since there are multiple workcenterids in the table and I only want the specific one that is part of the min operation sequence record.
Any help would be appreciated.
