I want to convert rows as column (like PIVOT) and i am unable to get if the number of values increases.
Below is my table.
i want the output like this.
I have used the following queries to acheive this but no luck.
Query1
Create table #temp(instanceid int, submissionid int, name1 varchar(20), value1 varchar(20))
insert into #temp(instanceid,submissionid,name1,value1)
Select 5151,5532,'Question_1','Y'
union
Select 5151,5532,'First','Mujda'
union
Select 5151,5532,'Last','Zhublawar'
union
Select 5151,5532,'Question_1','Y'
union

You need an extra field to get some order in that data with all the duplicates.
For example a primary key.
Then you can use a pivot with a row_number that uses that extra field in the order by.
Then concat the row_number with the name1, and Pivot on those.
For example :
create table #temp (id int identity(1,1), instanceid int, submissionid int, name1 varchar(20), value1 varchar(20));
insert into #temp(instanceid,submissionid,name1,value1) values
(5151,5532,'First','Mujda'),
(5151,5532,'Last','Zhublawar'),
(5151,5532,'Question_1','Y'),
(5151,5532,'First','Mujda1'),
(5151,5532,'Last','Zhublawar1'),
(5151,5532,'Question_1','Y'),
(5151,5532,'First','Mujda1'),
(5151,5532,'Last','Zhublawar1'),
(5151,5532,'Question_1','Y'),
(5151,5533,'First','Muthu'),
(5151,5533,'Last','Kumar'),
(5151,5533,'Question_1','Y'),
(5151,5534,'First','Suresh'),
(5151,5534,'Last','Kumar'),
(5151,5534,'Question_1','Y'),
(5151,5534,'First','Suresh1'),
(5151,5534,'Last','Kumar1'),
(5151,5534,'Question_1','Y');

To do it the dynamic way, here's some SQL to generate a #SQL variable.
declare #T table (name1 varchar(20));
insert into #T select name1 from #temp group by name1 order by name1;
declare #SQL nvarchar(max);
declare #Fields1 nvarchar(max);
declare #Fields2 nvarchar(max);
SELECT #Fields2 = STUFF((select ', ' + quotename(name1) from #T order by name1 FOR XML PATH('')),1,1,'');
SET #Fields2 = replace(#Fields2,']','1]')+','+char(13)+replace(#Fields2,']','2]')+','+char(13)+replace(#Fields2,']','3]');
SELECT #Fields1 = STUFF((select ',$' + quotename(name1+n)+' as '+quotename(nx+' '+name1) from (
select '1' as n, '1st' as nx, name1 from #T union all
select '2', '2nd' as nx, name1 from #T union all
select '3', '3rd' as nx, name1 from #T
) q order by n, name1 FOR XML PATH('')),1,1,'');
SET #Fields1 = replace(#Fields1,'$',char(13));
SET #SQL =
'SELECT
instanceid,
submissionid,'+#Fields1+'
FROM (
select
instanceid,
submissionid,
concat(name1, row_number() over (partition by instanceid, submissionid, name1 order by id)) as name_rn, value1
from #temp
) t
PIVOT( MAX(value1)
FOR name_rn IN ('+char(13)+#Fields2+')
) AS Pvt';
select #SQL;
--Get unique values of pivot column
SELECT #PivotColumns= COALESCE(#PivotColumns + ',','') + QUOTENAME(seq)
FROM (
select DISTINCT (name1) as seq
from #temp group by value1,name1,instanceid
) AS PivotExample
This are is your problem you are concatenating a row_number into the name1 value which would always be null. Your column list needs to be the DISTINCT values in name1 NOT what you want them to be in the end. If you want to rename columns you would alias them after the pivot or change the value in name1 prior to running the pivot.
So in the above code I removed the ROW_NUMBER() and added DISTINCT to the derived table.
Also note the test data you included has some instanceid & submissionid combinations that are missing certain fields like first name, or question. It looks like when copying and pasting you just didn't correct the correlations.
I have complicated query which works pretty good (MS SQL 2012). But it makes a mistake when sum up same price items. It count them correctly but only takes price once instead of taking them as a count number. It only appears when same item has same price and from same country. Here is my query ;

As you can see there are 2 "playstation" from "Russia" it takes correct count (2x) but only take 1 price "151$" (normally it must be 302$). How can I fix this without making major changes from query? Thank you.
I think this does what you want. The problem is in your first CTE where you do the item count and get a distinct on the ItemName, CountryName, and Price.
Instead of getting a distinct, do a group by as shown below and SUM the price.
SELECT I.NAME ITEMNAME, C.NAME COUNTRYNAME
,SUM(CAST(REPLACE(TAB.PRICE,'$','')AS INT))PRICE
,COUNT(CASE WHEN TAB.PRICE IS NOT NULL THEN 1 ELSE NULL END) CNTITEM
FROM [#Pre-Request] PR
LEFT JOIN #Items I ON PR.ITEMID=I.ID
LEFT JOIN #COUNTRY C ON PR.COUNTRYID = C.ID
OUTER APPLY
(
SELECT R.preReqId,R.winOfferId,O.PRICE
FROM #Request R
JOIN #Offers O ON R.winOfferId=O.Id
WHERE PR.ID=R.preReqId
)TAB
GROUP BY
I.NAME
,C.NAME

Here are the results I get:

Currently building a SELECT statement in SQL Server 2008 but would like to make this SELECT statement dynamic, so the columns can be defined based on values in a table. I heard about pivot table and cursors, but seems kind of hard to understand at my current level, here is the code;
DECLARE #date DATE = null
IF #date is null
set # date = GETDATE() as DATE
SELECT
Name,
value1,
value2,
value3,
value4
FROM ref_Table a
FULL OUTER JOIN (
SELECT
PK_ID ID,
sum(case when FK_ContainerType_ID = 1 then 1 else null) Box,
sum(case when FK_ContainerType_ID = 2 then 1 else null) Pallet,
sum(case when FK_ContainerType_ID = 3 then 1 else null) Bag,
sum(case when FK_ContainerType_ID = 4 then 1 else null) Drum
from
Packages
WHERE
#date between PackageStart AND PackageEnd
group by PK_ID ) b on a.Name = b.ID
where
Group = 0
The following works great for me , but PK_Type_ID and the name of the column(PackageNameX,..) are hard coded, I need to be dynamic and it can build itself based on present or futures values in the Package table.
Any help or guidance on the right direction would be greatly appreciated...,
As requested
ref_Table (PK_ID, Name)
1, John
2, Mary
3, Albert
4, Jane
Packages (PK_ID, FK_ref_Table_ID, FK_ContainerType_ID, PackageStartDate, PackageEndDate)
1 , 1, 4, 1JAN2014, 30JAN2014
2 , 2, 3, 1JAN2014, 30JAN2014
3 , 3, 2, 1JAN2014, 30JAN2014
4 , 4, 1, 1JAN2014, 30JAN2014
ContainerType (PK_ID, Type)
1, Box
2, Pallet
3, Bag
4, Drum
and the result should look like this;
Name Box Pallet Bag Drum
---------------------------------------
John 1
Mary 1
Albert 1
Jane 1
The following code like I said works great, the issue is the Container table is going to grow and I need to replicated the same report without hard coding the columns.
What you need to build is called a dynamic pivot. There are plenty of good references on Stack if you search out that term.
Here is a solution to your scenario:
IF OBJECT_ID('tempdb..##ref_Table') IS NOT NULL
DROP TABLE ##ref_Table
IF OBJECT_ID('tempdb..##Packages') IS NOT NULL
DROP TABLE ##Packages
IF OBJECT_ID('tempdb..##ContainerType') IS NOT NULL
DROP TABLE ##ContainerType
SET NOCOUNT ON
CREATE TABLE ##ref_Table (PK_ID INT, NAME NVARCHAR(50))
CREATE TABLE ##Packages (PK_ID INT, FK_ref_Table_ID INT, FK_ContainerType_ID INT, PackageStartDate DATE, PackageEndDate DATE)
CREATE TABLE ##ContainerType (PK_ID INT, [Type] NVARCHAR(50))
INSERT INTO ##ref_Table (PK_ID,NAME)
SELECT 1,'John' UNION
SELECT 2,'Mary' UNION
SELECT 3,'Albert' UNION
SELECT 4,'Jane'
INSERT INTO ##Packages (PK_ID, FK_ref_Table_ID, FK_ContainerType_ID, PackageStartDate, PackageEndDate)
SELECT 1,1,4,'2014-01-01','2014-01-30' UNION
SELECT 2,2,3,'2014-01-01','2014-01-30' UNION
SELECT 3,3,2,'2014-01-01','2014-01-30' UNION
SELECT 4,4,1,'2014-01-01','2014-01-30'
INSERT INTO ##ContainerType (PK_ID, [Type])
SELECT 1,'Box' UNION
SELECT 2,'Pallet' UNION
SELECT 3,'Bag' UNION
SELECT 4,'Drum'
DECLARE #DATE DATE, #PARAMDEF NVARCHAR(MAX), #COLS NVARCHAR(MAX), #SQL NVARCHAR(MAX)
SET #DATE = '2014-01-15'
SET #COLS = STUFF((SELECT DISTINCT ',' + QUOTENAME(T.[Type])
FROM ##ContainerType T
FOR XML PATH, TYPE).value('.', 'NVARCHAR(MAX)'),1,1,'')
SET #SQL = 'SELECT [Name], ' + #COLS + '
FROM (SELECT [Name], [Type], 1 AS Value
FROM ##ref_Table R
JOIN ##Packages P ON R.PK_ID = P.FK_ref_Table_ID
JOIN ##ContainerType T ON P.FK_ContainerType_ID = T.PK_ID
WHERE #DATE BETWEEN P.PackageStartDate AND P.PackageEndDate) X
PIVOT (COUNT(Value) FOR [Type] IN (' + #COLS + ')) P
'
PRINT #COLS
PRINT #SQL
SET #PARAMDEF = '#DATE DATE'
EXEC SP_EXECUTESQL #SQL, #PARAMDEF, #DATE=#DATE

Following my tutorial below will help you to understand the PIVOT functionality:
We write sql queries in order to get different result sets like full, partial, calculated, grouped, sorted etc from the database tables. However sometimes we have requirements that we have to rotate our tables. Sounds confusing?
Let's keep it simple and consider the following two screen grabs.
SQL Table:
Expected Results:
Wow, that's look like a lot of work! That is a combination of tricky sql, temporary tables, loops, aggregation......, blah blah blah
Don't worry let's keep it simple, stupid(KISS).
MS SQL Server 2005 and above has a function called PIVOT. It s very simple to use and powerful. With the help of this function we will be able to rotate sql tables and result sets.
Simple steps to make it happen:
Identify all the columns those will be part of the desired result set.
Find the column on which we will apply aggregation(sum,ave,max,min etc)
Identify the column which values will be the column header.
Specify the column values mentioned in step3 with comma separated and surrounded by square brackets.
So, if we now follow above four steps and extract information from the above sales table, it will be as below:
Year, Month, SalesAmount
SalesAmount
Month
[Jan],[Feb] ,[Mar] .... etc
We are nearly there if all the above steps made sense to you so far.
Now we have all the information we need. All we have to do now is to fill the below template with required information.
Template:
Our SQL query should look like below:
SELECT *
FROM
(
SELECT SalesYear, SalesMonth,Amount
FROM Sales
) AS SourceTable
PIVOT
(
SUM(Amount )
FOR SalesMonth
IN ( [Jan],[Feb] ,[Mar],
[Apr],[May],[Jun] ,[Jul],
[Aug],[Sep] ,[Oct],[Nov] ,[Dec])
) AS PivotTable;
In the above query we have hard coded the column names. Well it's not fun when you have to specify a number of columns.
However, there is a work arround as follows:
DECLARE #columnList nvarchar (MAX)
DECLARE #pivotsql nvarchar (MAX)
SELECT #columnList = STUFF(
(
SELECT ',' + '[' + SalesMonth + ']'
FROM Sales
GROUP BY SalesMonth
FOR XML PATH( '')
)
,1, 1,'' )
SET #pivotsql =
N'SELECT *
FROM
(
SELECT SalesYear, SalesMonth,Amount
FROM Sales
) AS SourceTable
PIVOT
(
SUM(Amount )
FOR SalesMonth
IN ( ' + #columnList +' )
) AS PivotTable;'
EXEC sp_executesql #pivotsql
Hopefully this tutorial will be a help to someone somewhere.
Enjoy coding.

Msg 240, Level 16, State 1, Line 2
Types don't match between the anchor and the recursive part in column "nm" of recursive query "cte".
Where am I making the mistake?
Exactly what it says:
'name1' has a different data type to 'name' + CAST((rn+1) as varchar(255))
Try this (untested)
;with cte as
(
select 1 as rn, CAST('name1' as varchar(259)) as nm
union all
select rn+1,nm = 'name' + CAST((rn+1) as varchar(255))
from cte a where rn<10)
select * from cte
Basically, you have to ensure the length matches too. For the recursive bit, you may have to use CAST('name' AS varchar(4)) if it fails again
You need to cast both nm fields
;with cte as
(
select 1 as rn,
CAST('name1' AS VARCHAR(255)) as nm
union all
select rn+1,
nm = CAST('name' + CAST((rn+1) as varchar(255)) AS VARCHAR(255))
from cte a where rn<10)
select * from cte
For me problem was in different collation.
Only this helped me:
;WITH cte AS (
SELECT
1 AS rn,
CAST('name1' AS NVARCHAR(4000)) COLLATE DATABASE_DEFAULT AS nm
UNION ALL
SELECT
rn + 1,
nm = CAST('name' + CAST((rn + 1) AS NVARCHAR(255)) AS NVARCHAR(4000)) COLLATE DATABASE_DEFAULT
FROM cte a WHERE rn < 10)
SELECT *
FROM cte;
Hope it can help someone else.
;with cte as
(
select 1 as rn, 'name' + CAST(1 as varchar(255)) as nm
union all
select rn+1,nm = 'name' + CAST((rn+1) as varchar(255))
from cte a where rn<10)
select * from cte
In my case, I messed up the sequence of columns in top and bottom clauses of UNION ALL. And it turned out that a varchar column appeared 'under' an int one. An easy mistake to make of you have lots of columns
If you use CONCAT in the recursive term of a rcte, since the output type of concat is varchar(MAX), you only need to cast the column in the initial query:
WITH rcte AS (
SELECT 1 AS nr, CAST('1' AS varchar(MAX)) AS trail
UNION ALL
SELECT nr+1, CONCAT(trail, '/', nr+1)
FROM rcte
WHERE nr < 5
)
SELECT * FROM rcte;
I would recommend using nvarchar(max)
WITH CTE AS (
SELECT x,x_name FROM (VALUES (1,CAST('' AS nvarchar(MAX)))) AS test(x,x_name)
UNION ALL
SELECT x + 1 x, CONCAT(x_name,x+1) FROM CTE WHERE x < 10 )
SELECT * FROM CTE
WITH rcte AS (
SELECT 1 AS nr, CAST('1' AS varchar(MAX)) AS trail
UNION ALL
SELECT nr+1, cast(CONCAT(trail, '/', nr+1) as varchar(max))
FROM rcte
WHERE nr < 5
)
SELECT * FROM rcte;
;with tmp1(NewsId,DataItem ,HeaderText)
as

STUFF(HeaderText, 1, CHARINDEX(',',HeaderText+','), '')
from Currentnews
union all
select NewsId, LEFT(HeaderText, CHARINDEX(',',HeaderText+',')-1),
STUFF(HeaderText, 1, CHARINDEX(',',HeaderText+','), '')
from tmp1
where HeaderText > ''
)
select NewsId, DataItem
from tmp1
order by NewsId
