Hi Guys ,

I built windows application form and connected to the database through LINQ ADO.NET entity Data Model.

Now I added some Datagridview to my app and I'm trying to write code to show columns from multiple tables but really don't know how to do it.

Can someone give me example how to write this code.

Here is the SQL code with all the tables and columns I need to show in my C# application datagrid.

use RMSmasterDB
select a.ItemLookupCode, a.Description, a.price AS CurrentPrice, CONVERT(DATE,a.DateCreated) AS DateCreated, CONVERT(DATE,a.LastReceived) AS LastRcvd, CONVERT(DATE,a.LastSold) AS LastSold, a.Quantity, QtyRcvd.QtyRcvd, QtySold.QtySold,QtySold.TotalProfit,SoldQ1.SoldQ1, SoldQ2.SoldQ2, SoldQ3.SoldQ3, soldq4.SoldQ4, soldq5.SoldQ5, 

AVG(SoldQ1.SoldQ1 + SoldQ2.SoldQ2 + SoldQ3.SoldQ3 + soldq4.SoldQ4 + soldq5.SoldQ5) AS AVGQuaters, a.ReorderPoint


from dbo.item AS A 


left join (

select  b.ItemID, SUM(b.Quantity) AS QtySold, SUM(b.price * b.quantity) AS TotalProfit
from dbo.TransactionEntry AS B 
group by b.ItemID

           ) AS QtySold on Qtysold.ItemID = a.ID



left join (

select c.ItemID, SUM(c.QuantityReceivedToDate) AS QtyRcvd
from dbo.PurchaseOrderEntry AS C 
group by c.ItemID

           ) AS QtyRcvd on QtyRcvd.itemid = a.ID


left join (

select d.ItemID, ISNULL(SUM(d.quantity),0) AS SoldQ1
from dbo.TransactionEntry AS D
where d.TransactionTime >= dateadd(day,datediff(day,92,GETDATE()),0)
and
d.TransactionTime <= dateadd(day,datediff(day,0,GETDATE()),0)
group by d.ItemID

          ) SoldQ1 on SoldQ1.ItemID = a.ID


left join (

select e.ItemID, ISNULL(SUM(e.quantity),0) AS SoldQ2
from dbo.TransactionEntry AS e
where e.TransactionTime >= dateadd(day,datediff(day,184,GETDATE()),0)
and
e.TransactionTime <= dateadd(day,datediff(day,93,GETDATE()),0)
group by e.ItemID

          ) SoldQ2 on SoldQ2.ItemID = a.ID

left join (

select f.ItemID, ISNULL(SUM(f.quantity),0) AS SoldQ3
from dbo.TransactionEntry AS f
where f.TransactionTime >= dateadd(day,datediff(day,276,GETDATE()),0)
and
f.TransactionTime <= dateadd(day,datediff(day,185,GETDATE()),0)
group by f.ItemID

          ) SoldQ3 on SoldQ3.ItemID = a.ID

left join (

select g.ItemID, ISNULL(SUM(g.quantity),0) AS SoldQ4
from dbo.TransactionEntry AS g
where g.TransactionTime >= dateadd(day,datediff(day,368,GETDATE()),0)
and
g.TransactionTime <= dateadd(day,datediff(day,277,GETDATE()),0)
group by g.ItemID

          ) SoldQ4 on SoldQ4.ItemID = a.ID


left join (

select H.ItemID, ISNULL(SUM(H.quantity),0) AS SoldQ5
from dbo.TransactionEntry AS H
where H.TransactionTime >= dateadd(day,datediff(day,460,GETDATE()),0)
and
H.TransactionTime <= dateadd(day,datediff(day,369,GETDATE()),0)
group by H.ItemID

          ) SoldQ5 on SoldQ5.ItemID = a.ID




left join dbo.Department AS Q on q.id = a.DepartmentID

where q.code = '05'

group by a.ItemLookupCode, a.Description, a.price, a.DateCreated, a.LastReceived, a.LastSold, a.Quantity, QtyRcvd.QtyRcvd, QtySold.QtySold,SoldQ1.SoldQ1, SoldQ2.SoldQ2, SoldQ3.SoldQ3, soldq4.SoldQ4, soldq5.SoldQ5, QtySold.TotalProfit, a.ReorderPoint



order by QtySold.TotalProfit DESC
