I have stuck in a select statement, converting rows into columns. I have tried with PIVOT, i was able to convert the single column. But my requirement is little different. I have explained the requirement below.
I have a table structure as below,
I want to select the data as below,
The values in the table are dynamic, which is not a problem for me to deal with that. But i need a way to get the below result.
Could someone please give me a hint on doing it, may be a way to modify the PIVOT below.
select *
from
(
select TSID,AID,Count,BID
from tbl TS
WHERE TS.TPID = 1
) src
pivot
(
sum(Count)
for AID in (AID1,AID2,AID3)
) piv
Thank you..

EDIT
This will work for not previously known column names
DECLARE #Columns AS VARCHAR(MAX)
DECLARE #SQL AS VARCHAR(MAX)
SELECT #Columns = STUFF(( SELECT DISTINCT ',' + AID
FROM Table1
FOR
XML PATH('')
), 1, 1, '')
SET #SQL = '
;WITH MyCTE AS
(
SELECT TSID,
AID,
STUFF(( SELECT '','' + CONVERT(VARCHAR,[Count] )
FROM Table1 I Where I.TSID = O.TSID
FOR
XML PATH('''')
), 1, 1, '''') AS CountList
FROM Table1 O
GROUP BY TSID,
AID
)
SELECT *
FROM MyCTE
PIVOT
(
MAX(CountList)
FOR AID IN
(
' + #Columns + '
)
) AS PivotTable'
EXEC(#SQL)

I am working in SQL Server 2014 and below is my database with which I am working on and need some analysis done on it.
Upon inspecting the database sample carefully we can notice a number 8777 in L9 and in L13 column.
Now I want to get only those columns which have 8777 in them and in the end a column named "count" which shows how many times the number appeared means I need in output something like this as shown below:
So far I have written this query which is giving the category and subcategory correct. But it is showing all the columns. I have no idea how to count the occurrences of a number and show its count in a count column.
select *
from Sheet2$
where '8777' IN ([L1],[L2],[L3],[L4],[L5],[L6],[L7],[L8],[L9],[L10],[L11],[L12],[L13]
To dynamically limit the columns, you would need Dynamic SQL
Example
Select *
Into #Temp
From YourTable A
Unpivot ( Value for Item in ([L1], [L2],[ L3], [L4], [L5], [L6], [L7], [L8], [L9], [L10], [L11], [L12], [L13]) ) u
Where Value = 8777
Declare #SQL varchar(max) = Stuff((Select Distinct ',' + QuoteName(Item) From #Temp Order by 1 For XML Path('')),1,1,'')
Select #SQL = '
Select *,[Count] = sum(1) over()
From #Temp A
Pivot (max(Value) For [Item] in (' + #SQL + ') ) p'
Exec(#SQL);
Returns
Category SubCategory L13 L9 Count
C1 SC1 NULL 8777 2
C1 SC3 8777 NULL 2
Hmmm. I think you want the original rows with the count. I think this is:
declare #cols nvarchar(max);
declare #sql nvarchar(max);
set #cols = (select distinct ', ' + v.colname
from t cross apply
(values ('l1', l1),
('l2', l2),
('l3', l3),
('l4', l4),
('l5', l5),
('l6', l6),
('l7', l7),
('l8', l8),
('l9', l9),
('l10', l10),
('l11', l11),
('l12', l12),
('l13', l13)
) v(colname, val)
where v.val = '8777'
for xml path ('')
);
set #sql = '
select category, subcategory' + #cols + ',
count(*) over () as cnt
from t
';
exec sp_executesql #sql;
The only difference from your result is that the count is on every row. That can easily be adjusted using a case expression, but I'm not sure it is necessary.
If you want the count in only one row, then:
set #sql = '
select category, subcategory' + #cols + ',
(case when row_number() over (order by category, subcategory) = 1
then count(*) over ()
end) as cnt
from t
order by category, subcategory
';
You can try this part as a replacement of John's answer's second query to get the proper count, it does not achieve the exact thing you want but can be a work around.
Declare #sql varchar(max) = Stuff((Select Distinct ',' + QuoteName(Item)
From #Temp Order by 1 For XML Path('')),1,1,'')
print #sql;
Select #SQL = '
Select *,value=8777
From #Temp A
Pivot (Count(Value) For [Item] in (' + #sql + ') ) p'
print #sql;
Exec(#SQL);
I just used count function in pivot in place of sum.
I am trying to use POVIT while looking at this example This
Here is the Code:
CREATE DATABASE DEMO
GO
USE DEMO
GO
-- Creating table for demo
IF (object_id('TblPivot','U') > 0)
DROP TABLE TblPivot
CREATE TABLE TblPivot
(
ItemCode int,
ItemName varchar(100),
ItemColour varchar(50)
)
GO
-- Inerting some sample records
INSERT INTO TblPivot
SELECT 1,'Samsung Mobile','Red'
UNION ALL
SELECT 2,'Nokia Mobile','Blue'
UNION ALL
SELECT 3,'Nokia Mobile','Green'
UNION ALL
SELECT 4,'Motorola Mobile','Red'
UNION ALL
SELECT 5,'Samsung Mobile','Green'
UNION ALL
SELECT 2,'Nokia Mobile','Blue'
UNION ALL
SELECT 1,'Samsung Mobile','Red'
UNION ALL
SELECT 2,'Nokia Mobile','Blue'
GO
And here is the PIVOT selection
-- Getting table data
SELECT
ItemCode,
ItemName,
ItemColour
from TblPivot
GO
-- Getting agreegated data using Pivot and converted rows to column
SELECT
*
FROM
(
SELECT
ItemCode,
ItemName,
ItemColour
FROM TblPivot
) AS P
PIVOT
(
Count(ItemName) FOR ItemColour IN (Red, Blue, Green)// Here is the Issue
where it knows what words to give it like Red,Blue,Green what I want is to use
what ever the ItemColur it could be 100s What ever you get
from the data base use that for the `IN(ItemColur)`
) AS pv
GO
It keeps saying that The column name "ItemColur" specified in the PIVOT operator conflicts with the existing column name in the PIVOT argument.
How can I get this working with that I even tried to make a Temp Table didn't work
This is the code for dynamic PIVOT:
DECLARE #columns NVARCHAR(MAX), #sql NVARCHAR(MAX);
SET #columns = N'';
SELECT #columns += N', p.' + QUOTENAME(ItemColour)
FROM (SELECT distinct p.ItemColour FROM dbo.TblPivot AS p
) AS x;
SET #sql = N'
SELECT itemcode, ' + STUFF(#columns, 1, 2, '') + '
FROM
(
SELECT p.itemcode, p.ItemName, p.ItemColour
FROM dbo.TblPivot AS p
) AS j
PIVOT
(
COUNT(ItemName) FOR ItemColour IN ('
+ STUFF(REPLACE(#columns, ', p.[', ',['), 1, 1, '')
+ ')
) AS p;';
PRINT #sql;
EXEC sp_executesql #sql;
The output for above query looks like this:
This is my data in table (left join from field table and value table)
This is my expected result table after use pivot function
Thanks for help ^___^
I suggest you to use dynamic SQL as fieldnames number may very in future:
DECLARE #columns nvarchar(max),
#sql nvarchar(max)
SELECT #columns = COALESCE(#columns,'') + ',' + QUOTENAME(c.fieldname)
FROM [Columns] c
ORDER BY c.cid
SELECT #sql = N'
SELECT *
FROM (
SELECT v.[row],
c.fieldname,
v.fieldvalue
FROM [Values] v
INNER JOIN [Columns] c
ON v.cid = c.cid
) t
PIVOT (
MAX(fieldvalue) FOR fieldname IN ('+STUFF(#columns,1,1,'')+')
) pvt'
EXEC sp_executesql #sql
Will output:
row FirstName LastName Email Phone
1 Arnun Saelim Arnun.s#outlook.com 0922743838
2 Micheal Saelim Micheal#gmail.com 0886195353
I'm not sure why group by got into your mind, but here is a working example of what you are trying to achieve.
select * into #temp from
( values
(1,'A','AV'),
(1,'B','BV'),
(1,'C','CV'),
(2,'A','AV'),
(2,'B','BV'),
(2,'C','CV'))
as t(row, FieldName, FieldValue)
select *
from #temp
PIVOT
(MAX(FieldValue) FOR FieldName in ([A],[B],[C])) as pvt
Does that work for you?
I currently have the following script which is pivoting results from rows into columns. It works a Great, apart from two issues;
I have a flag in another table which I want to filter by (basically: WHERE Table.Stats=YES). I'd normally do this in a basic query with an inner join followed by that WHERE statement. In the query below, I already have a WHERE FileSeq=25, which works, but this criteria I need to get working is calling on a different table.
The query is returning a lot of uncessary NULL fields.
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
SELECT #cols = STUFF((SELECT ',' + QUOTENAME(col+CAST(rn AS varchar(6)))
FROM
(
SELECT row_number() over(partition by UID ORDER BY ClassCode) rn
FROM dbo.StudentClasses
) d
CROSS APPLY
(
SELECT 'ClassCode', 1
) c (col, so)
GROUP BY col, rn, so
ORDER BY rn, so
FOR XML PATH(''), TYPE
).VALUE('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT UID,' + #cols + '
FROM
(
SELECT UID, col+CAST(rn AS varchar(10)) col, VALUE
FROM
(
SELECT UID, classcode,
row_number() over(partition by UID ORDER BY classcode) rn
FROM StudentClasses WHERE FileSeq=25
) t
CROSS APPLY
(
SELECT ''classcode'', CAST(classcode AS varchar(6))
) c (col, VALUE)
) x
PIVOT
(
MAX(VALUE)
for col in (' + #cols + ')
) p '
EXECUTE(#query)
Any assistance appreciated
I'm working on a dynamic pivot query on a table that contains:
OID - OrderID
Size - size of the product
BucketNum - the order that the sizes
should go
quantity - how many ordered
The size column contains different sizes depending upon the OID.
So, using the code found here, I put this together:
DECLARE #listCol VARCHAR(2000)
DECLARE #query VARCHAR(4000)
SELECT #listCol = STUFF(( SELECT distinct '], [' + [size]
FROM #t
FOR
XML PATH('')
), 1, 2, '') + ']'
SET #query = 'SELECT * FROM
(SELECT OID, [size], [quantity]
FROM #t
) src
PIVOT (SUM(quantity) FOR Size
IN (' + #listCol + ')) AS pvt'
EXECUTE ( #query )
This works great except that the column headers (the sizes labels) are not in the order based upon the bucketnum column. The are in the order based upon the sizes.
I've tried the optional Order By after the pivot, but that is not working.
How do I control the order in which the columns appear?
Thank you
You need to fix this:
SELECT #listCol = STUFF(( SELECT distinct '], [' + [size]
FROM #t
FOR
XML PATH('')
), 1, 2, '') + ']'
To return the columns in the right order. You might have to do something like this instead of using DISTINCT:
SELECT [size]
FROM #t
GROUP BY [size]
ORDER BY MIN(BucketNum)
SELECT #listCol = STUFF(
(SELECT DISTINCT ',' + QUOTENAME(size) AS [size]
FROM #t
ORDER BY [size]
FOR XML PATH('')
I saw this link just today, which uses a CTE to build the column list (which, presumably, you could order) on the fly without the need for dynamic sql:
http://blog.stevienova.com/2009/07/13/using-ctes-to-create-dynamic-pivot-tables-in-sql-20052008/
I had the same problem and tried the solution suggested above but, probably due to my level of understanding, couldn't get it to work. I found a simple hack was to create a Temp table with the column headers ordered correctly using Order by statements and then pull in that list to the variable that sets the dynamic pivot query column names.
e.g.
SELECT WeekNum INTO #T3
FROM #T2
GROUP BY WeekNum
ORDER BY MIN(WeekNum)
SELECT #ColumnName1 = ISNULL(#ColumnName1 + ',','') + QuoteName(WeekNum)
FROM (SELECT WeekNum From #T3) AS WeekNum
Worked a treat.
Hope that helps someone.
