I have a requirement of creating a view for pivot table
This is my source table
According to my requirement I have created the following pivot table
DECLARE #cols AS NVARCHAR(MAX), #query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME(Date)
from Salse_Data
group by Date
order by Date
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT Product,' + #cols + ' from
(
select Product, Date, Salse
from Salse_Data
) x
pivot
(
sum(Salse)
for Date in (' + #cols + ')
) p '
execute(#query);
Output is
I need to create an indexed view(Materialized View) above query
So i used procedure to create the view
CREATE PROCEDURE [dbo].[ProductSalse_By_Year_Proc_4]
AS
BEGIN
DECLARE #cols AS NVARCHAR(MAX), #query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME(Date)
from Salse_Data
group by Date
order by Date
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'CREATE VIEW abcd with schemabinding as SELECT Product,' + #cols + ' from
(
select Product, Date, Salse
from Salse_Data
) x
pivot
(
sum(Salse)
for Date in (' + #cols + ')
) p '
EXECUTE(#query)
END
GO
this execuce without errors but not created the view.
Could you please help on this issue?

I have created a dynamic pivot and my table has two same dates with diff values ..
i m facing an error when try the pivot
Error : the column 'JUN-2015' was specified multiple times for 'P'
...........................................................
CREATE TABLE #REVENUE
(
ID INT PRIMARY KEY IDENTITY(1,1) NOT NULL,
[MONTH] VARCHAR(8) NOT NULL,
SALES DECIMAL(8,2) NOT NULL
)
INSERT INTO #REVENUE
([MONTH],SALES)
VALUES
('JAN-2015', 200000.16),
('FEB-2015', 220000.17),
('MAR-2015', 227000.55),

('JUN-2015', 265756.75)
DECLARE #cols AS NVARCHAR(MAX) ,
#query AS NVARCHAR(MAX)
SELECT #cols = STUFF((SELECT ',' + QUOTENAME([MONTH])
FROM #REVENUE
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')

SELECT #query =

(SELECT

PIVOT
(
AVG(SALES)
for [MONTH] in (' + #cols + ')

EXEC SP_EXECUTESQL #query
If you select #cols you'll see the issue
Please use DISTINCT to avoid the situation:
SELECT #cols = STUFF((SELECT DISTINCT ',' + QUOTENAME([MONTH])
FROM #REVENUE
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
I want to convert Row into column as shown in below Expected result image.
I have a table and getting data as shown Existing Table image.
Designation Column has dynamic value(Number of value is not fix)
I tried:
DECLARE #cols AS NVARCHAR(MAX),#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME(designation)
from MyTable
group by designation
order by designation
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)'),1,1,'')
set #query = N'SELECT ' + #cols + N' from
(
select SanctionStrength , designation from MyTable
) x
pivot
(
max(SanctionStrength) for designation in (' + #cols + N')
) p '
exec sp_executesql #query;
I am getting result as expected but only for SS.
How can i bind value of AS and VAC together.
you need to combine columns before pivot.
DECLARE #cols AS NVARCHAR(MAX),#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME(designation)
from MyTable
group by designation
order by designation
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)'),1,1,'')
set #query = N'SELECT Row, ' + #cols + N' from
(
select ''SS'' Row, SS AS Value , designation from MyTable
UNION ALL
select ''AS'' Row, [AS] AS Value , designation from MyTable
UNION ALL
select ''Vac'' Row, Vac AS Value , designation from MyTable
) x
pivot
(
max(Value) for designation in (' + #cols + N')
) p '
exec sp_executesql #query;
I have a dynamic stored procedure which runs in SSMS. Is it possible to convert this proc into a function so when ever I do
exec function stored.proc
I can run this from my ETL?
My query as below -
create procedure dbo.bear_load
as
set nocount on;
Declare #cols as NVARCHAR(MAX), #query as NVARCHAR(MAX), #Result as NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME(FIELD_NAME)
from bear_crossjoin
group by Field_Name, FIELDNUMBER
order by FIELDNUMBER
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = N'SELECT ' + #cols + N'
from
(
select substring, Field_Name,
rn = row_number() over(partition by field_name order by fieldnumber)
from bear_crossjoin
) x
pivot
(
max(substring)
for Field_Name in (' + #cols + N')
) p '
set #Result= ' select ' + #query
EXEC (#query)
GO
exec dbo.bear_load
Any help very much appreciated.

Is it possible to exclude some vaules from the PIVOT results.
Referencing this question i would like to know if it is posible to exclude the columns in the Pivot table that has 0 value.
Imagine there is a count of 0 for EventType Meeting, is it possible not to show it at all?
i hope you have implemented following solution from the question
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT distinct ',' + QUOTENAME(EventType)
from dbo.testTable
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT year,' + #cols + '
from
(
select EventType,
year = year(date)
from dbo.testTable
) x
pivot
(
count(EventType)
for EventType in (' + #cols + ')
) p '
execute(#query)
if so then you can do following
DECLARE #cols AS NVARCHAR(MAX),
#where AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT distinct ',' + QUOTENAME(EventType)
from dbo.testTable
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
select #where = ' where ' + STUFF((SELECT distinct ' Or ' + QUOTENAME(EventType) + ' <> 0 '
from dbo.testTable
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,2,3,'')
set #query = 'SELECT year,' + #cols + '
from
(
select EventType,
year = year(date)
from dbo.testTable
) x
pivot
(
count(EventType)
for EventType in (' + #cols + ')
) p ' + #where
execute(#query)
I have the following query which is always giving the error. Could some body help me
to resolve this?
"Incorrect syntax near the keyword '#stqsql'".
My code is:
declare #strsql nvarchar(max)
set #strsql=select merchantid from employee
select *
from
(
Select s.employeeid,
COUNT(*) as TotCount
from Employee s
GROUP BY s.employeeid
)as a
pivot (avg(TotCount) for employeeid IN ('+#stqsql+')) AS NoOfRec
Unfortunately the way you are trying to get dynamic columns does not work. You will have to use something similar to the following:
DECLARE #colsPivot AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
-- this gets the list of values that you want to pivot
select #colsPivot = STUFF((SELECT distinct ', ' + QUOTENAME(merchantid )
from employee
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
-- since you are use a dynamic list you have to use dynamic sql
set #query = 'SELECT ' + #colsPivot + ' from
(
SELECT s.employeeid,
COUNT(*) as TotCount
FROM Employee s
GROUP BY s.employeeid
) src
pivot
(
avg(TotCount)
for employeeid in (' + #colsPivot + ')
) p '
execute(#query)
