Here is my query. But i get VAT and A.Vat values as Null

SELECT *

Please Help
The only distinct value is TaxVal so I suspect you are trying to do following:
WITH Src AS --Your source table
(
SELECT * FROM (VALUES
(7, 1, 1, 1, 1, 4.00),
(7, 1, 1, 1, 1, 1.00)

)
SELECT * FROM
(
SELECT iItemKey, Qty, FreeQty, Unit, TaxCatKey, TaxVal, CASE WHEN TaxVal = 1.00 THEN 'VAT' ELSE 'A.VAT' END Col
FROM Src
) T
PIVOT (MAX(TaxVal) FOR Col IN ([VAT], [A.VAT])) P
I have data like this. first row of Id 1 from particular time period and second row of id 1 is another time period. so now want to combined id and name which are same in the two time periods reaming are same.if there is no orders from that time period its should be display 0 or null.

From what I understood from your Question and Comments:
Schema for your case
SELECT * INTO #TAB FROM(
SELECT 1 ID, 'ROSE' NAME, 4 QTY, 540 PRICE
UNION ALL
SELECT 1 , 'ROSE' , 1 , 640

SELECT 3 , 'GRAND' , 10 ,360
UNION ALL
SELECT 4 , NULL,NULL,NULL
UNION ALL
SELECT 4 , 'LOTUS' , 9 , 580

And the Logic to display is as below
SELECT CASE WHEN SNO=1 THEN CAST(ID AS VARCHAR(250)) ELSE '' END ID,
CASE WHEN SNO=1 THEN ISNULL(NAME,'') ELSE '' END NAME,ISNULL(Qty,0)Qty
,ISNuLL(Price,0)Price FROM (
SELECT ROW_NUMBER() Over(partition by Name, Id ORDER BY (SELECT 1)) SNO
,ID, NAME , Qty, Price, ID AS ID2 FROM #TAB

ORDER BY ID2, NAME DESC
Try this from your Procedure. And may need to do type cast based on your actual datatypes

custid custname month count
------------------------------
1 A 1 1
2 B 1 1
2 B 2 4
3 C 1 1
6 D 1 1
According to the following rules:
All channel views subscription is billed every 15 days. If the
customer viewed the same channel within the 15 days, he will only be
billed once for that channel. For instance, custid 2, custname B his billing cycle is 19 Jan - 3 Feb (one billing cycle), 4 Feb - 20 Feb (one billing cycle) and so on. Therefore, he is billed only 1 time in Jan since he watch the same channel throughout the billing cycle; and he is billed 4 times in Feb for watching (channelid 7, 8, 9) and channelid 7 watched on 27 Feb (since this falls in another billing cycle, customer B is also charged here). Customer B is not charged on 2 Feb for watching channel 2 since he was already billed in 19 jan - 3 Feb billing cycle.
An invoice is generated every month for each customer, therefore, the
results should show the 'Month' and the 'Count' of the channels
viewed for each customer.
Can this be done in SQL server?

I don't know why you get 1 in count field for customer A. He got:
ABSS 2016-01-09 +1 to count (+15 days = 2016-01-24)
SSJ 2016-01-28 +1 to count
ABSS 2016-01-28 +1 to count (28-01 > 24.01)
So in January there must be count = 3.
Whenever I am trying to count things with complex criteria, I use a sum and case statement. Something like below:
SELECT custid, custname,
SUM(CASE WHEN somecriteria
THEN 1
ELSE 0
END) As CriteriaCount
FROM whateverTable
GROUP BY custid, custname
You can make that somecriteria variable as complicated a statement as you like, so long as it returns a boolean. If it passes, this row returns a 1. If it fails, the row reutrns a 0, then we sum up the values returned to get the count.
Generally this is how you can get any number (10 in this example) of fixed 15 day intervals starting at the given date (#dd in this example).
DECLARE #dd date = CAST('2016-01-19 17:30' AS DATE);
WITH E1(N) AS (
SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL
SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL
SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1),
E2(N) AS (SELECT 1 FROM E1 a, E1 b),
E4(N) AS (SELECT 1 FROM E2 a, E2 b), --10,000 rows max
tally(N) AS (SELECT TOP (10) ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM E4)
SELECT
startd = DATEADD(D,(N-1)*15, #dd),
endd = DATEADD(D, N*15-1, #dd)
FROM tally
Adapt it to the rules defining how start date must be calculated for the user (and probably chanel).
#Sturgus what if I want to define it in the code? Any other
alternatives besides defining it in the table? How to write a query

Well, one way or another, you will have to save each customer's billing start date (minimally). If you want to do this entirely in SQL without 'editing the database', something like the following should work. The drawback to this approach is that you would need to manually edit the "INSERT INTO" statement every month to suit your needs. If you were allowed to edit the already existing customers table or create a new one, then it would reduce this manual effort.
DECLARE #CustomerBillingPeriodsTVP AS Table(
custID int UNIQUE,
BillingCycleID int,
BillingStartDate Date,
BillingEndDate Date
);
INSERT INTO #CustomerBillingPeriodsTVP (custID, BillingCycleID, BillingStartDate, BillingEndDate) VALUES
(1, 1, '2016-01-03', '2016-01-18'), (2, 1, '2016-01-18', '2016-02-03'), (3, 1, '2016-01-15', '2016-01-30'), (6, 1, '2016-01-14', '2016-01-29');
SELECT A.custid, A.custname, B.BillingCycleID AS [month], COUNT(DISTINCT A.channelid) AS [count]
FROM dbo.tblCustomerChannelViews AS A INNER JOIN #CustomerBillingPeriodsTVP AS B ON A.custid = B.CustID
GROUP BY A.custid, A.custname, B.BillingCycleID;
GO
Where are you getting your customers' billing start dates as it is?
I'm not sure how this solution will scale - but with some good index candidates and decent data housekeeping, it'll work..
You're going to need some extra info for starters, and to normalize your data. You will need to know the first charging period start date for each customer. So store that in a customer table.
Here are the tables I used:
create table #channelViews
(
custId int, channelId int, viewDate datetime
)
create table #channel
(
channelId int, channelName varchar(max)
)
create table #customer
(
custId int, custname varchar(max), chargingStartDate datetime
)
I'll populate some data. I won't get the same results as your sample output, because I don't have the appropriate start dates for each customer. Customer 2 will be OK though.
insert into #channel (channelId, channelName)
select 1, 'ABSS'
union select 2, 'STHHG'
union select 4, 'XGGTS'
union select 3, 'SSJ'
union select 7, 'UUJKS'
union select 8, 'AKKDC'
union select 9, 'GGSK'
insert into #customer (custId, custname, chargingStartDate)
select 1, 'A', '4 Jan 2016'
union select 2, 'B', '19 Jan 2016'
union select 3, 'C', '5 Jan 2016'
union select 6, 'D', '5 Jan 2016'
insert into #channelViews (custId, channelId, viewDate)
select 1,1,'2016-01-09'
union select 2,2,'2016-01-19'
union select 3,4,'2016-01-09'
union select 6,4,'2016-01-09'
union select 2,2,'2016-01-26'
union select 2,2,'2016-01-28'
union select 1,3,'2016-01-28'
union select 1,1,'2016-01-28'
union select 2,2,'2016-02-02'
union select 2,7,'2016-02-10'
union select 2,8,'2016-02-10'
union select 2,9,'2016-02-10'
union select 2,9,'2016-02-11'
union select 2,7,'2016-02-27'
And here is the somewhat unweildy query, in a single statement.
The two underlying sub-queries are actually the same data, so there may be more appropriate / efficient ways to generate these.
We need to exclude from billing any channel charged in the same charging period C for the previous Month. This is the essence of the join. I used a right-join so that I could exclude all such matches from the results (using old.custId is null).
select c.custId, c.[custname], [month], count(*) [count] from
(
select new.custId, new.channelId, new.month, new.chargingPeriod
from
(
select distinct cv.custId, cv.channelId, month(viewdate) [month], (convert(int, cv.viewDate) - convert(int, c.chargingStartDate))/15 chargingPeriod
from #channelViews cv join #customer c on cv.custId = c.custId
) old
right join
(
select distinct cv.custId, cv.channelId, month(viewdate) [month], (convert(int, cv.viewDate) - convert(int, c.chargingStartDate))/15 chargingPeriod
from #channelViews cv join #customer c on cv.custId = c.custId
) new
on old.custId = new.custId
and old.channelId = new.channelId
and old.month = new.Month -1
and old.chargingPeriod = new.chargingPeriod
where old.custId is null
group by new.custId, new.month, new.chargingPeriod, new.channelId
) filteredResults
join #customer c on c.custId = filteredResults.custId
group by c.custId, [month], c.custname
order by c.custId, [month], c.custname
And finally my results:
custId custname month count
1 A 1 3
2 B 1 1
2 B 2 4
3 C 1 1
6 D 1 1
This query does the same thing:
select c.custId, c.custname, [month], count(*) from
(
select cv.custId, min(month(viewdate)) [month], cv.channelId
from #channelViews cv join #customer c on cv.custId = c.custId
group by cv.custId, cv.channelId, (convert(int, cv.viewDate) - convert(int, c.chargingStartDate))/15
) x
join #customer c
on c.custId = x.custId
group by c.custId, c.custname, x.[month]
order by custId, [month]
I have a table with the following data :

11-Dec-12 DEF 1 15
11-Dec-12 DEF 2 16
and I want to query on it for a particular date 11-Dec-2012 to get the following output :
Stock Buy Sell Mid Change
--------------------------------------
ABC 11.5 12.5 12.0 0.5
DEF 15 16 15.5
Since DEF does not have data for the previous date, change should be blank for it.
I have created the following query :
Select Stock,
AVG(CASE BuySell WHEN 1 THEN DayClose END) AS 'Buy',
AVG(CASE BuySell WHEN 2 THEN DayClose END) As 'Sell',
Sum(DayClose/2) as 'Mid',
Sum(Change/2) AS Change
FROM (
select t1.Stock, t1.BuySell, t1.DayClose, Sum(t1.DayClose - t2.DayClose) as Change
FROM #myTable as t1 inner join #myTable as t2 on
t1.Stock = t2.Stock
where
t1.TradeDate = '2012-12-11' AND
t2.TradeDate = (SELECT TOP 1 TradeDate FROM #myTable WHERE TradeDate < '2012-12-11' ORDER BY TradeDate DESC)
GROUP BY
t1.Stock, t1.buysell, t1.dayclose ) AS P1 GROUP BY stock
I created a temp table #mytable for this purpose :
drop table #mytable
CREATE TABLE #myTable
(
TradeDate datetime,
stock varchar(20),
buysell int,
dayclose decimal(10,2)
)
insert into #mytable values ('10-dec-2012', 'abc' , 1, 11)
insert into #mytable values ('10-dec-2012', 'abc' , 2, 12)
insert into #mytable values ('11-dec-2012', 'abc' , 1, 11.5)
insert into #mytable values ('11-dec-2012', 'abc' , 2, 12.5)
insert into #mytable values ('11-dec-2012', 'def' , 1, 15)
insert into #mytable values ('11-dec-2012', 'def' , 2, 16)
But I am not able to get the required output, rather getting
Stock Buy Sell Mid Change
--------------------------------------------------------------
abc 11.500000 12.500000 12.00000 1.00
Can someone tell me where am I going wrong. I seem to be lost in here.
Thanks,
Monika
Please try:
;WITH T1 as(
SELECT a.TradeDate
,a.stock
,SUM(CASE WHEN a.BuySell = 1 THEN a.DayClose ELSE 0 END) Buy
,SUM(CASE WHEN a.BuySell = 2 THEN a.DayClose ELSE 0 END) Sell
,SUM(a.DayClose) / 2 AS Mid
FROM #mytable a
GROUP BY a.TradeDate, a.stock
)SELECT t.*,
t.Mid - PR.Mid AS Change
FROM T1 t
LEFT JOIN
T1 PR ON
PR.TradeDate = DATEADD(DAY, -1, t.TradeDate)
AND PR.stock = t.stock
Try this:
SELECT a.TradeDate
,a.stock
,SUM(CASE WHEN a.BuySell = 1 THEN a.DayClose ELSE 0 END) Buy
,SUM(CASE WHEN a.BuySell = 2 THEN a.DayClose ELSE 0 END) Sell
,SUM(a.DayClose) / 2 AS Mid
INTO #temp
FROM #mytable a
GROUP BY a.TradeDate, a.stock
SELECT t.*,
t.Mid - previousRecord.Mid AS Change
FROM #temp t
LEFT JOIN
#temp previousRecord ON
previousRecord.TradeDate = DATEADD(DAY, -1, t.TradeDate)
AND previousRecord.stock = t.stock
DROP TABLE #temp
All you have to do now is to select the data for a date.
Select Stock,
AVG(CASE BuySell WHEN 1 THEN DayClose END) AS 'Buy',
AVG(CASE BuySell WHEN 2 THEN DayClose END) As 'Sell',
Sum(DayClose/2) as 'Mid',
Sum(Change/2) AS Change
FROM (

FROM #myTable as t1 left join #myTable as t2 on t2.TradeDate = (SELECT TOP 1 TradeDate FROM #myTable WHERE TradeDate < t1.TradeDate ORDER BY TradeDate DESC)
and t1.Stock = t2.Stock and t1.buysell=t2.buysell
where
t1.TradeDate = '11-12-2012'
How do you do a query to calculate how much of an item has been consumed (used up)?
We can find the qty of each item that we purchased in a purchases table with columns Id, ProductId, Qty (decimal), Date
Id, ProductId, Qty, Date
1, 1, 10, 1/1/11
2, 1, 5, 2/2/11
3, 1, 8, 3/3/11
And how do you then add a count of how many of each row in the purchase table have been consumed - assuming strict FIFO? So in the above example if we know that 14 have been consumed the output would be:
Id, ProductId, Qty, Date, Consumed
1, 1, 10, 1/1/11, 10
2, 1, 5, 2/2/11, 4
3, 1, 8, 3/3/11, 0
Hopefully that explains what I mean by an amount consumed query - we know 14 were consumed and that the first purchase was for 10, so all 10 have been consumed. The next purchase was for 5 so we know that 4 of those have been consumed.
Theres two places I can get the consumed data from - the ConsumedItems table: columns Id, ProductId, QtyUsed, Date), or from the ConsumedSummaryView with columns ProductId, QtyUsed (this is the sum of ConsumedItems.QtyUsed)
Sample table and view
create table purchases (Id int, ProductId int, Qty int, Date datetime)
insert purchases select 1, 1, 10, '1/1/11'
insert purchases select 2, 1, 5, '2/2/11'
insert purchases select 3, 1, 8, '3/3/11'
create view ConsumedSummaryView as select ProductID = 1, QtyUsed = 14
The query
;with p as (
select *, rn=ROW_NUMBER() over (partition by productid order by date, id)
from purchases)
, tmp(Id, ProductId, Qty, Date, rn, ToGo, Consumed) as (
select p.Id, p.ProductId, p.Qty, p.Date, cast(1 as bigint),
CAST(ISNULL(v.qtyused,0) - p.Qty as decimal(20,10)),
cast(case
when v.qtyused >= p.Qty Then p.Qty
when v.qtyused > 0 then v.qtyused
else 0 end as decimal(20,10))
from p
left join ConsumedSummaryView v on p.ProductId = v.productId
where rn=1
union all
select p.Id, p.ProductId, p.Qty, p.Date, cast(p.rn as bigint),
cast(ISNULL(tmp.toGo,0) - p.Qty as decimal(20,10)),
cast(case
when tmp.toGo >= p.Qty Then p.Qty
when tmp.toGo > 0 then tmp.toGo
else 0 end as decimal(20,10))
from tmp
--inner join p on p.rn=tmp.rn+1
inner join p on p.rn=tmp.rn+1 and p.productid = tmp.ProductId
)
select Id, ProductId, Qty, Date, Consumed
from tmp
order by rn
Output
Id ProductId Qty Date Consumed
----------- ----------- ----------- ----------------------- -----------
1 1 10 2011-01-01 00:00:00.000 10

A little different approach than Richard's, but I'm not sure which will perform better:
SELECT
Purchases.Id,
Purchases.ProductId,
Purchases.Qty,
Purchases.Date,
CASE
WHEN COALESCE (PreviousPurchases.PreviousUsed, 0) + Qty < ConsumedSummaryView.QtyUsed THEN Qty
ELSE
CASE
WHEN ConsumedSummaryView.QtyUsed - COALESCE (PreviousPurchases.PreviousUsed, 0) < 0 THEN 0
ELSE ConsumedSummaryView.QtyUsed - COALESCE (PreviousPurchases.PreviousUsed, 0)
END
END AS Used
FROM
Purchases
INNER JOIN ConsumedSummaryView ON Purchases.ProductId = ConsumedSummaryView.ProductId
LEFT OUTER JOIN (
SELECT
SUM(Purchases_2.Qty) AS PreviousUsed,
Purchases_1.Id
FROM
Purchases AS Purchases_2
INNER JOIN Purchases AS Purchases_1 ON Purchases_2.Id < Purchases_1.Id
AND Purchases_2.ProductId = Purchases_1.ProductId
GROUP BY
Purchases_1.Id
) AS PreviousPurchases ON Purchases.Id = PreviousPurchases.Id
