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)

I have the following data output from my database

I've tried to figure out how to use PIVOT-table to make this work but cannot make it work. The date is dynamic depending on a date in the database. The output I am looking for is like below. Can someone please point me into right direction?
Look at the fiddle what I've tried so far I know it is using SUM right now, and that is not correct, but I cannot figure out what to use. http://sqlfiddle.com/#!3/0bd0c/4
PS. The data and the image are not related, so don't be fooled by the image. It is just an example
Is this what you were looking for:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT DISTINCT ',' + QUOTENAME(ColumnName)
from tempData
group by ColumnName, name
FOR XML PATH(''), Type
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = N'SELECT Name, ' + #cols + N' from
(
select Name, value, ColumnName
from tempData
) x
pivot
(
SUM(value)
for ColumnName in (' + #cols + N')
) p '
exec sp_executesql #query;
Changing this in your fiddle return the rows as you need it.
Try it like this:
DECLARE #cols AS NVARCHAR(MAX)=
STUFF(
(
SELECT DISTINCT ',[' + ColumnName + ']'
FROM tempData
FOR XML PATH('')
)
,1,1,'');
DECLARE #SqlCmd VARCHAR(MAX)=
'SELECT p.*
FROM
(
SELECT *
FROM tempData
) AS tbl
PIVOT
(
SUM(Value) FOR ColumnName IN(' + #cols +')
) AS p';
EXEC(#SqlCmd);
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 data in below format. this data is coming through SQL Query.
i want to show it in below format either by query or by rdlc report.
You need to use dynamic SQL to make it.
From your expected result you can try to follow thoes step to make it.
use row_number function make row number by Name, because we need to join base on that row_number.
get the use MAX and MIN to make row number calendar table. from 1 to max(rn). the table can let use outer join
declare a var #tables to make the OUTER JOIN execute SQL (each LEFT JOIN maen a group of Crew#).
declare a var #col to make column, which you want to select (Employee) from each table.
then use execute dynamic execute it.
look like this.
create table T
(
Name varchar(50),
Employee VARCHAR(50)
)
insert into T values ('Crew#1','TR123');
insert into T values ('Crew#1','311');
insert into T values ('Crew#2','DDD');
insert into T values ('Crew#2','12121');
insert into T values ('Crew#1','SDDAS');
insert into T values ('Crew#3','31114312');
insert into T values ('Crew#3','DD14124D');
insert into T values ('Crew#3','1214124121');
insert into T values ('Crew#3','SDD412AS');
DECLARE #tables AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX),
#col AS NVARCHAR(MAX);
SET #tables = STUFF((SELECT distinct ' LEFT JOIN ' + ' (SELECT * FROM CTE WHERE Name = '''+Name+''') '+QUOTENAME(Name)+' on t1.smallRN = '+QUOTENAME(Name)+'.rn'
FROM T
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
SET #col = STUFF((SELECT distinct ', ' + QUOTENAME(Name)+'.Employee as '''+ QUOTENAME(Name) +''''
FROM T
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
SET #col = substring(#col,1, len(#col))
set #query = '
WITH CTE AS (
SELECT *,ROW_NUMBER() OVER(PARTITION BY Name ORDER BY Name) rn
FROM T
),CTE1 AS(
SELECT MIN(rn) smallRN,MAX(rn) bigRN
FROM CTE
UNION ALL
SELECT smallRN+1,bigRN
FROM CTE1
WHERE smallRN < bigRN
)
SELECT '+#col+'
FROM CTE1 t1 ' + #tables
execute(#query)

First we will create a temp table where we will stock the data that you have and your table
create table #table1
(
[Crew Name] varchar(500) ,
Employee varchar(500)
)
INsert into #table1
values (....)
select * from #table1
Dynamic selection
then we will create a dynamic query to get the columns that we have, that way we can add as much crews as we want,
declare #DynamicPivotQuery as nvarchar(max)
declare #ColumnName as nvarchar(max)
select #ColumnName = ISNULL(#ColumnName +',','') + QUOTENAME([Crew Name])
from (select distinct [Crew Name] from #table1) as Country
set #DynamicPivotQuery = N'select ' +#ColumnName + '
from #table1
Pivot ( MAX(Employee)
FOR [Crew Name] in (' +#ColumnName+')) as Pivoted
'
exec (#DynamicPivotQuery)
this way we will get only the first row for every column
so we have to find a way to aggregate and get the other columns as well just to demonstrate i will union the Mmin also this is where i stoped my testes but you can do more then this with some testes
now the union :
declare #DynamicPivotQuery as nvarchar(max)
declare #ColumnName as nvarchar(max)
select #ColumnName = ISNULL(#ColumnName +',','') + QUOTENAME([Crew Name])
from (select distinct [Crew Name] from #table1) as Country
set #DynamicPivotQuery = N'select ' +#ColumnName + '
from #table1
Pivot ( MAX(Employee)
FOR [Crew Name] in (' +#ColumnName+')) as Pivoted
union
select ' +#ColumnName + '
from #table1
Pivot ( MIN(Employee)
FOR [Crew Name] in (' +#ColumnName+')) as Pivoted
'
exec (#DynamicPivotQuery)
here is the result :
if you follow this way i'm sure that you will find a way to union all the result
You can add this result into a temp table
then add a column which will be a reference into this temp table
then use pivot function
To know more about pivot Visit :

you can use also SSIS to a very handy tool and easy to use
Using dynamic PIVOT if you dont have a set Crew columns.

I have the following structure in a SQL Server 2008 database. I am trying to create a script to replicate the output shown below.
It is generated by:
groupby on RPT_ID, FILE_ID, LINE_ID,
distinct columns from COLUMN_LITH and 'first' values in COLUMN_VALUES (COLUMN_NAME is dropped)
I am a beginner in SQL so this is beyond me. Any help whatsoever would be greatly appreciated.
Thanks in advance

Using dynamic pivot, it might be an option.
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX);
SET #cols = STUFF((SELECT distinct ',' + QUOTENAME(c.column_name)

I have dynamic sql query as below.
DECLARE #cols AS NVARCHAR(MAX) = '[0],[3],[11]',
#query AS NVARCHAR(MAX)
SET #query = N'SELECT * FROM
(
SELECT
year(createdDate) as [year],month(createdDate) as [month],cp.product_Id as product_ID,cp.salesprice as Amount
FROM customer_products cp
)s
PIVOT
(
SUM(Amount)
FOR product_Id IN ( '+ #cols +' ))
AS pvt;'
EXECUTE(#query)
Question:
Above query works however below query is not working because of
SELECT #cols = CONCAT(#cols, '[', cast(product_ID as varchar),']') FROM Product
code block.Error displays Incorrect syntax near
DECLARE #cols AS NVARCHAR(MAX) = '',
#query AS NVARCHAR(MAX)
SELECT #cols = CONCAT(#cols, '[', cast(product_ID as varchar),'],') FROM Product
SET #query = N'SELECT * FROM
(
SELECT
year(createdDate) as [year],month(createdDate) as [month],cp.product_Id as product_ID,cp.salesprice as Amount
FROM customer_products cp
)s
PIVOT
(
SUM(Amount)
FOR product_Id IN ( '+ #cols +' ))
AS pvt;'
EXECUTE(#query)
Where i miss exactly what is missing in above query while selecting productID from Product ?
You need to remove last , from #cols, add
SET #cols = LEFT(#cols, LEN(#cols) - 1)
You can consider using XML instead CONCAT like:
SELECT #cols = STUFF((SELECT ',' + QUOTENAME(CAST(product_ID as VARCHAR(10)))
FROM Products
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
, 1, 1, '');
It is a good practice to define length for cast(product_ID as varchar(10))
You need to ensure the last comma is removed from the select list, or you're passing an empty value to PIVOT.
Use this:
DECLARE #cols AS NVARCHAR(MAX) = '',
#query AS NVARCHAR(MAX)
SELECT #cols = COALESCE(#cols+', ','') + '[' + cast(product_ID as varchar) + ']' FROM product
SET #query = N'SELECT * FROM
(
SELECT
year(createdDate) as [year],month(createdDate) as [month],cp.product_Id as product_ID,cp.salesprice as Amount
FROM customer_products cp
)s
PIVOT
(
SUM(Amount)
FOR product_Id IN ( '+ #cols +' ))
AS pvt;'
EXECUTE(#query)
