i have a problem with pivot table in SQL Server:
I have a table with the next information (i dont know how much different values could have column1):
Column1 Value
---------------
PRODUCT_4 1
PRODUCT_4 2
PRODUCT_4 3
PRODUCT_6 10
PRODUCT_6 20
PRODUCT_6 30
PRODUCT_8 100
PRODUCT_8 200
PRODUCT_8 300
... ...
PRODUCT_X 1
PRODUCT_X 2
PRODUCT_X 3
I want to transform this into a pivot table to get the next output:
product_4 product_6 product_8 ... product_x
1 10 100 1
2 20 200 2
3 30 300 3
I was using the next query:
DECLARE
#cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME(column1)
from dbo.Context_Table
group by column1
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
print #cols
set #query = N'SELECT ' + #cols + N' from
(
select value, Column1
from dbo.Context_Table
) x
pivot
(
max(value)
for Column1 in (' + #cols + N')
) p '
exec sp_executesql #query;
But the ouput is not that i expected...
PRODUCT_4 PRODUCT_6 PRODUCT_8 PRODUCT_X
3 30 300 3
My question is... how can i get all the values without using the aggregate function MAX?
Thanks all!
add ROW_NUMBER() to your dynamic pivot:
set #query = N'SELECT ' + #cols + N' from
(
select ROW_NUMBER() OVER (PARTITION BY Column1 ORDER BY value) RN , value, Column1
from ##T
) x
pivot
(
max([value])
for Column1 in (' + #cols + N')
) p '
exec sp_executesql #query;
You must add a changing column to your query, I do this with ROW_NUMBER():
Just try it out:
DECLARE #tbl TABLE(Column1 VARCHAR(100),[Value] INT)
INSERT INTO #tbl VALUES
('PRODUCT_4',1)
,('PRODUCT_4',2)
,('PRODUCT_4',3)
,('PRODUCT_6',10)
,('PRODUCT_6',20)
,('PRODUCT_6',30)
,('PRODUCT_8',100)
,('PRODUCT_8',200)
,('PRODUCT_8',300)
,('PRODUCT_X',1)
,('PRODUCT_X',2)
,('PRODUCT_X',3)
SELECT p.*
FROM
(
SELECT ROW_NUMBER() OVER(PARTITION BY Column1 ORDER BY [Value]) AS ValueInx
,*
FROM #tbl AS t
) AS tbl
PIVOT
(
MAX([Value]) FOR Column1 IN(PRODUCT_4,PRODUCT_6,PRODUCT_8,PRODUCT_X)
) AS p:
The result
+----------+-----------+-----------+-----------+-----------+
| ValueInx | PRODUCT_4 | PRODUCT_6 | PRODUCT_8 | PRODUCT_X |
+----------+-----------+-----------+-----------+-----------+
| 1 | 1 | 10 | 100 | 1 |
+----------+-----------+-----------+-----------+-----------+
| 2 | 2 | 20 | 200 | 2 |
+----------+-----------+-----------+-----------+-----------+
| 3 | 3 | 30 | 300 | 3 |
+----------+-----------+-----------+-----------+-----------+
You will easily integrate this into your dyanmic approach...
Try this/ Or something along these lines.
select PRODUCT_4,PRODUCT_6,PRODUCT_8
from
(select name,value,row_number() over (partition by name order by value) as id from product) p
pivot
(
max(value)
for name
IN( PRODUCT_4,PRODUCT_6,PRODUCT_8)
)
as a
Hope this helps.
Thanks.

I am trying to get an SQL Server Dynamic Pivot table to work that allows me to count and then sum the number of columns. The purpose of the pivot table is to create a report of all the days individuals were staying in a city and the total number of days(in a month). So, for example, Person A was staying everyday in June - the total will be 30.Person B only started staying on the 3rd of June - the total will be 27 etc. The data table only consists of Name, ArriveDate, DepartDate...the days of the month are created through an SQL query.
+------+------------+------------+-------+-------+-------+-----+-------+-------+-------+
| Name | ArriveDate | DepartDate | 06-01 | 06-02 | 06-03 | ... | 06-29 | 06-30 | Total |
+------+------------+------------+-------+-------+-------+-----+-------+-------+-------+
| A | 2014-06-01 | 2014-06-23 | 1 | 1 | 1 | ... | 1 | 1 | 30 |
| B | 2014-06-02 | 2014-06-23 | 0 | 1 | 1 | ... | 1 | 1 | 27 |
| C | 2014-06-02 | 2014-06-23 | 0 | 0 | 0 | ... | 1 | 1 | 16 |
+------+------------+------------+-------+-------+-------+-----+-------+-------+-------+
Here is the query I have so far:
DROP TABLE #tempDates
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
;WITH cte (datelist, maxdate) AS
(
SELECT MIN(ArriveDate) datelist,
EOMONTH(GETDATE()) AS maxdate
FROM Reservation
UNION ALL
SELECT dateadd(dd, 1, datelist), maxdate
FROM cte
WHERE datelist < maxdate
)
SELECT c.datelist
INTO #tempDates
FROM cte c
SELECT #cols = STUFF(( SELECT distinct ',' + QUOTENAME(convert(CHAR(10), datelist, 120))
FROM #tempDates
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
SET #query = 'SELECT ID,
ArriveDate,
DepartDate,
' + #cols + '
FROM
(
SELECT r.ID,
r.ArriveDate,
r.DepartDate,
d.datelist,
convert(CHAR(10), datelist, 120) PivotDate
FROM
Reservation r
LEFT JOIN
#tempDates d
ON d.datelist BETWEEN rg.ArriveDate AND GETDATE()
) x
pivot
(
COUNT(datelist)
FOR PivotDate IN (' + #cols + ')
) p '
EXECUTE (#query)
Here is my attempt using a dynamic crosstab:

I have requirement of sorting dynamically made column from row.
I have following structure of data in SQL :
All attributes are treated as column but actually it stored in DB as row and their respective TextValue(If type is Text),DateValue (if type is date time or date)
Id | TextValue | DateValue | Attribute
--------------------------------------------
1 | abc | - | SiteLocation
2 | - | 1-1-2013 | Holiday date
3 | xyz | - | SiteLocation
4 | - | 2-2-2014 | Holiday date
5 | pqr | - | SiteLocation
6 | abc | - | SiteLocation
I want to apply sorting on SiteLocation and I am displaying it as column.
So how can i achieve this
SiteLocation | Holiday date
abc | -
- | 1-1-2013
xyz |-
- |2-2-2014
pqr |-
abc |-
I want to apply sorting on SiteLcoation or Holiday date in UI grid.
Please suggest me some way how can I do it?
Here is your table
CREATE TABLE #TEMP(Id INT,TextValue VARCHAR(100),DateValue DATE,Attribute VARCHAR(100))
INSERT INTO #TEMP
SELECT 1 Id, 'abc' TextValue ,NULL DateValue ,'SiteLocation' Attribute
UNION ALL
SELECT 2 ,NULL ,'1-1-2013' ,'Holiday date'
UNION ALL
SELECT 3 ,'xyz' ,NULL ,'SiteLocation'
UNION ALL
SELECT 4 , NULL ,'2-2-2014' ,'Holiday date'
UNION ALL
SELECT 5 ,'pqr' ,NULL ,'SiteLocation'
UNION ALL
SELECT 6 ,'abc' ,NULL ,'SiteLocation'
QUERY
SELECT [SiteLocation],[Holiday DATE]
FROM
(
SELECT ID,ISNULL(TextValue,DateValue) VALUE,Attribute
FROM #TEMP
)P
PIVOT
(
min(VALUE) FOR
Attribute IN ([SiteLocation],[Holiday DATE])
)
AS i
SQL FIDDLE
UPDATE
I am updating the query as you suggested.
Here you will select the columns for converting rows to columns
DECLARE #cols NVARCHAR (MAX)
SELECT #cols = COALESCE (#cols + ',[' + [Attribute] + ']',
'[' + [Attribute] + ']')
FROM (SELECT DISTINCT [Attribute] FROM #TEMP) PV
ORDER BY [Attribute]
Now you can pivot dynamically here.
DECLARE #query NVARCHAR(MAX)
SET #query = '
-- Your pivoted columns will be displayed
SELECT ' + #cols + ' FROM
(
-- Combine into single column
SELECT ID,ISNULL(TextValue,DateValue) VALUE,Attribute
FROM #TEMP
) x
PIVOT
(
MIN(VALUE)
FOR [Attribute] IN (' + #cols + ')
) p
'
EXEC SP_EXECUTESQL #query

I apologize for my ignorance. I just am not familiar with pivot queries AT ALL and all the examples I find seem about as clear as mud. I have table that returns GroupName and ID Numbers.
For Example:
SELECT GroupName, IDnumber FROM do.Table_1
Returns
GroupName IDnumber
1 8395
1 A660
1 8396
1 A661
2 8398
2 A662
2 8399
What I want is something more like this:
GroupName ID1 ID2 ID3 ID4
1 8395 A660 8396 A661
2 8398 A662 8399 NULL
How can I do this? Pivot query? Some other method?
I am open to suggestion and appreciate any help you could provide.
Yes, you can do it using PIVOT but not in this shape, you have firstly to generate a row number to use it to format the data in the way you want. Something like this:
WITH Ranked
AS
(
SELECT GroupName, IDnumber,
ROW_NUMBER() OVER(PARTITION BY GroupName ORDER BY GroupName) AS RN
FROM Table1
)
SELECT GroupName,
[1] AS ID1, [2] AS ID2, [3] AS ID3, [4] AS ID4
FROM Ranked AS r
PIVOT
(
MAX(IDnumber)
FOR RN IN([1], [2], [3], [4])
) AS p;
SQL Fiddle Demo
This will give you:
| GROUPNAME | ID1 | ID2 | ID3 | ID4 |
|-----------|------|------|------|--------|
| 1 | 8395 | A660 | 8396 | A661 |
| 2 | 8398 | A662 | 8399 | (null) |
If you want to do it dynamically and not to write the row number by hand in the pivot table operator, you have to do it using dynamic SQL, something like:
DECLARE #cols AS NVARCHAR(MAX);
DECLARE #colnames AS NVARCHAR(MAX);
DECLARE #query AS NVARCHAR(MAX);
SELECT #cols = STUFF((SELECT distinct ',' +
QUOTENAME(RN)
FROM
(
SELECT ROW_NUMBER() OVER(PARTITION BY GroupName ORDER BY GroupName) AS RN
FROM Table1
) AS t
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
, 1, 1, '');
SELECT #colnames = STUFF((SELECT distinct ',' +
QUOTENAME(RN) + 'AS' +
QUOTENAME('ID' + CAST(RN AS NVARCHAR(5)))
FROM
(
SELECT ROW_NUMBER() OVER(PARTITION BY GroupName ORDER BY GroupName) AS RN
FROM Table1
) AS t
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
, 1, 1, '');
SELECT #query = 'WITH Ranked
AS
(
SELECT GroupName, IDnumber,
ROW_NUMBER() OVER(PARTITION BY GroupName ORDER BY GroupName) AS RN
FROM Table1
)
SELECT GroupName, ' + #colnames +
' FROM Ranked AS r
PIVOT
(
MAX(IDnumber)
FOR RN IN(' + #cols + ')' +
') p';
execute(#query);
SQL Fiddle Demo
This should give you the same result:
| GROUPNAME | ID1 | ID2 | ID3 | ID4 |
|-----------|------|------|------|--------|
| 1 | 8395 | A660 | 8396 | A661 |
| 2 | 8398 | A662 | 8399 | (null) |
You may need to use dynamic pivoting since the Id will be dynamic. Here is your sample table
SELECT * INTO #TEMP
FROM
(
SELECT 1 GroupName, '8395' IDnumber
UNION ALL
SELECT 1, 'A660'
UNION ALL
SELECT 1, '8396'
UNION ALL
SELECT 1, 'A661'
UNION ALL
SELECT 2, '8398'
UNION ALL
SELECT 2, 'A662'
UNION ALL
SELECT 2, '8399'
)TAB
Select row number over each Groupname and insert into a temporary table so that it can be used for both selecting the columns for pivoting and inside the pivot
SELECT *,
'ID' + CAST(ROW_NUMBER() OVER(PARTITION BY GroupName ORDER BY GROUPNAME) AS VARCHAR(10)) IDS
INTO #NEWTABLE
FROM #TEMP
Select columns for pivot
DECLARE #cols NVARCHAR (MAX)
SELECT #cols = COALESCE (#cols + ',[' + IDS + ']',
'[' + IDS + ']')
FROM (SELECT DISTINCT IDS FROM #NEWTABLE) PV
ORDER BY IDS
Now pivot dynamically
DECLARE #query NVARCHAR(MAX)
SET #query = '
SELECT * FROM
(
SELECT * FROM #NEWTABLE
) x
PIVOT
(
MAX(IDnumber)
FOR IDS IN (' + #cols + ')
) p
'

I am trying to pivot on two columns in SQL Server 2008 on an invoice table. So I have data like the follows:
+--------------+--------+---------+------+
| Invoice Date | Item # | Dollars | Lbs. |
+--------------+--------+---------+------+
| 1/1/14 | A | 1 | 1 |
| 1/2/14 | B | 2 | 2 |
| 1/3/14 | A | 3 | 3 |
| 1/4/14 | B | 4 | 4 |
| 2/1/14 | A | 5 | 5 |
| 2/1/14 | B | 6 | 6 |
+--------------+--------+---------+------+
I would like to display it as
+--------+--------------+-----------------+--------------+-----------------+
| Item # | 1/31/14 Lbs. | 1/31/14 Dollars | 2/28/14 Lbs. | 2/28/14 Dollars |
+--------+--------------+-----------------+--------------+-----------------+
| A | 4 | 4 | 5 | 5 |
| B | 6 | 6 | 6 | 6 |
+--------+--------------+-----------------+--------------+-----------------+
Note the column name is the last day of that month and either dollars or pounds. I can do it just fine one column (either pounds or dollars) however I can't do it on both.
Here is my example code for just pounds:
DECLARE
#v_Columns VARCHAR(MAX),
#v_Query VARCHAR(MAX)
--pivot and delimit values
SELECT #v_Columns = COALESCE(#v_Columns,'[') + convert(varchar(8), InvoiceDate, 1) + ' Lbs.' + '],['
FROM
( SELECT DISTINCT dbo.ufn_GetLastDayOfMonth(InvoiceDate) As InvoiceDate
FROM Invoice
WHERE InvoiceDate BETWEEN #BEGIN_DATE AND #END_DATE
ORDER BY InvoiceDate
--delete last two chars of string (the ending ',[')
SET #v_Columns = SUBSTRING(#v_Columns, 1, LEN(#v_Columns)-2)
PRINT #v_Columns
--construct sql statement
SET #v_Query =
'WITH AllOrders (LastInvoiceDate, Item, Pounds) AS
(
SELECT
CONVERT(varchar(8), dbo.ufn_GetLastDayOfMonth(Invoice.InvoiceDate), 1) + ''' + ' Lbs.' + ''' As LastInvoiceDate,
Item,
Pounds
FROM INVOICE
WHERE InvoiceDate BETWEEN #BEGIN_DATE AND #END_DATE
)
SELECT *
FROM AllOrders
PIVOT
(
SUM(QuantityShipped)
FOR LastInvoiceDate IN (' + #v_Columns + ')
) AS pivotview'
Thank you all in advance!
In order to get the result you are going to have to either PIVOT twice or UNPIVOT the Dollars and Lbs columns into a single column and then apply the PIVOT once. My preference would be to unpivot and then pivot because I find it to be much easier.
Instead of working dynamically first, you should write the query as a static or hard-coded version to get the logic correct, then convert it to dynamic SQL. The example that I have uses your final dates 201-01-31, etc because you are using a function to create those dates and should be able to apply that as needed.
Since you are using SQL Server 2005+, you can use CROSS APPLY to unpivot Dollars and Lbs. The code will be similar to the following:
select
t.ItemNo,
new_col = convert(varchar(10), t.[invoice date], 120) + '_'+ c.col,
c.value
from yourtable t
cross apply
(
select 'Dollars', Dollars union all
select 'Lbs', Lbs
) c (col, value);
See SQL Fiddle with Demo. This converts your data to the following format:
| ITEMNO | NEW_COL | VALUE |
|--------|--------------------|-------|
| A | 2014-01-31_Dollars | 1 |
| A | 2014-01-31_Lbs | 1 |
| B | 2014-01-31_Dollars | 2 |
| B | 2014-01-31_Lbs | 2 |
| A | 2014-01-31_Dollars | 3 |
I've concatenated into new_col the final column names that you'll need. Again you can format the date in whatever format you need, I just used 2014-01-31 and added the Dollars or Lbs to the end of it. Once you've got the data, you will PIVOT the values into your final desired result:
select ItemNo,
[2014-01-31_Lbs], [2014-01-31_Dollars],
[2014-02-28_Lbs], [2014-02-28_Dollars]
from
(
select
t.ItemNo,
new_col = convert(varchar(10), t.[invoice date], 120) + '_'+ c.col,
c.value
from yourtable t
cross apply
(
select 'Dollars', Dollars union all
select 'Lbs', Lbs
) c (col, value)
) d
pivot
(
sum(value)
for new_col in ([2014-01-31_Lbs], [2014-01-31_Dollars],
[2014-02-28_Lbs], [2014-02-28_Dollars])
) p;
See SQL Fiddle with Demo. Now you've got the result you want, so simply convert it to dynamic SQL:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME(convert(varchar(10), t.[invoice date], 120) + '_'+ c.col)
from yourtable t
cross apply
(
select 'Lbs', 0 union all
select 'Dollars', 1
) c (col, so)
group by [invoice date], col, so
order by [invoice date], so
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT ItemNo,' + #cols + '
from
(
select
t.ItemNo,
new_col = convert(varchar(10), t.[invoice date], 120) + ''_''+ c.col,
c.value
from yourtable t
cross apply
(
select ''Dollars'', Dollars union all
select ''Lbs'', Lbs
) c (col, value)
) d
pivot
(
sum(value)
for new_col in (' + #cols + ')
) p '
exec sp_executesql #query;
See SQL Fiddle with Demo. This give a final result of:
| ITEMNO | 2014-01-31_LBS | 2014-01-31_DOLLARS | 2014-02-28_LBS | 2014-02-28_DOLLARS |
|--------|----------------|--------------------|----------------|--------------------|
| A | 4 | 4 | 5 | 5 |
| B | 6 | 6 | 6 | 6 |
Here is your sample table
CREATE TABLE #TEMP([Invoice Date] DATE,[Item #] VARCHAR(10),[DollarS] NUMERIC(10,0),[Lbs.] NUMERIC(10,0))
INSERT INTO #TEMP VALUES ('1/1/14', 'A',1,1)
INSERT INTO #TEMP VALUES ('1/2/14', 'B',2,2)
INSERT INTO #TEMP VALUES ('1/3/14', 'A',3,3)
INSERT INTO #TEMP VALUES ('1/4/14', 'B',4,4)
INSERT INTO #TEMP VALUES ('2/1/14', 'A',5,5)
INSERT INTO #TEMP VALUES ('2/1/14', 'B',6,6)
Now you need to apply UNION ALL(instead of UNPIVOT) and bring columns to row and combine the columns, get the order of columns as Date+LBS/DOLLARS.
SELECT DISTINCT DENSE_RANK() OVER(ORDER BY CAST(LASTDAY AS DATE),UNIT DESC)RNO,*,
CAST(DATEPART(MONTH,LASTDAY)AS VARCHAR) +'/'+ CAST(DATEPART(DAY,LASTDAY)AS VARCHAR) +'/' +RIGHT(CAST(YEAR(LASTDAY)AS VARCHAR),2)+' ' +UNIT PIVOTCOL
INTO #NEWTABLE
FROM
(
SELECT [Item #],'DOLLARS' UNIT,
DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,[Invoice Date])+1,0))LASTDAY,
SUM([Dollars]) OVER(PARTITION BY [Item #],DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,[Invoice Date])+1,0))) VALUE
FROM #TEMP
UNION ALL
SELECT [Item #], 'LBS.',
DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,[Invoice Date])+1,0))LASTDAY,
SUM([Lbs.]) OVER(PARTITION BY [Item #],DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,[Invoice Date])+1,0))) DOLLARSUM
FROM #TEMP
)TAB
Now declare the query to get the columns dynamically and to set NULL to Zero
DECLARE #cols NVARCHAR (MAX)
DECLARE #NullToZeroCols NVARCHAR (MAX)
SELECT #cols = COALESCE (#cols + ',[' + PIVOTCOL + ']',
'[' + PIVOTCOL + ']')
FROM (SELECT DISTINCT RNO,PIVOTCOL FROM #NEWTABLE) PV
ORDER BY RNO
PRINT #COLS
SET #NullToZeroCols = SUBSTRING((SELECT ',ISNULL(['+PIVOTCOL+'],0) AS ['+PIVOTCOL+']'
FROM(SELECT DISTINCT RNO,PIVOTCOL FROM #NEWTABLE GROUP BY RNO,PIVOTCOL)TAB
ORDER BY RNO FOR XML PATH('')),2,8000)
Now pivot the query
DECLARE #query NVARCHAR(MAX)
SET #query = 'SELECT [Item #],' + #NullToZeroCols + ' FROM
(
SELECT [Item #],VALUE,PIVOTCOL FROM #NEWTABLE
) x
PIVOT
(
SUM(VALUE)
FOR PIVOTCOL IN (' + #cols + ')
) p
ORDER BY [Item #];'
EXEC SP_EXECUTESQL #query

EXEC(#sql)
Here is SQL Fiddle
This approach uses dynamic PIVOT. In order to get the expected result ROW_NUMBER() with partitioning was used since values in param column are not unique.
UPDATE
You can also try it like this, but you have to manually add columns to the query:
SELECT SUM(CASE WHEN param = 1 THEN value ELSE 0 END) param1
, SUM(CASE WHEN param = 2 THEN value ELSE 0 END) param2
, SUM(CASE WHEN param = 3 THEN value ELSE 0 END) param3

If you don't want columns to be automatically handled, you can just use static PIVOT:
SELECT [1] AS param1
,[2] AS param2
FROM (
SELECT *
, ROW_NUMBER() OVER (PARTITION BY param ORDER BY param) n
FROM tbl) t
PIVOT (
MIN(value) FOR param IN ([1],[2])
) pvt
