Hi i have big problem with pivot ISNULL i try convert many topics to my code but i failed with this. Its my code with error:
DECLARE #PivotColumnHeaders VARCHAR(MAX);
SET #PivotColumnHeaders='';
SELECT #PivotColumnHeaders =#PivotColumnHeaders + '[' + CONVERT(VARCHAR,Magazyn1) + '],'
FROM
(
Select DISTINCT Pro.SC03002 as Magazyn1
From SC030700 as Pro
) as Topa
SET #PivotColumnHeaders = LEFT(ISNULL(#PivotColumnHeaders,0),LEN(#PivotColumnHeaders)-1)
DECLARE #Column VARCHAR(MAX);
set #Column =SUBSTRING(( select distinct ',IsNull(['+SC03003+'],0) as ['+SC03003+']' from SC030700 for xml path('')),2,8000)
DECLARE #cmd VARCHAR(MAX);
-Msg 8114, Level 16, State 5, Line 284(set #column)

From SC030700 as Pro
) AS myProducts
PIVOT (SUM(SC03003) FOR SC03002 IN ('+#PivotColumnHeaders+')) dynamicpivot '
EXECUTE (#cmd)
try casting column SC03003 to a varchar since you're adding it to a string value.
set #Column =SUBSTRING(( select distinct ',IsNull(['+ CONVERT(VARCHAR, SC03003)+'],0) as [' + CONVERT(VARCHAR, SC03003) +']' from SC030700 for xml path('')),2,8000)
You need to cast those numeric columns to varchar explicitly so you can concatenate them to your string:
set #Column =SUBSTRING(( select distinct ',IsNull(['+CAST(SC03003 AS varchar(31))+'],0) as [SC03003]' from SC030700 for xml path('')),2,8000)

Im new to Stack overflow and SQL and I'm trying to replicate a function in Microsoft Power Query to use in SQL instead.
I know how to Unpivot and keep 1 Column in SQL and then had to reference all the other columns by name to make the unpivot.
Now I need to Keep 3 ID columns and Unpivot the rest of the columns
(This table has 355 columns right now and will change)
Can anyone help me with this?
This is the furthest I got (Thanks to RAV DBLearning on Youtube), but I cant seem to find a way to Convert the columns types to 1 type.
DECLARE
#SQLSTRING NVARCHAR(MAX),
#COLUMNLIST NVARCHAR(1000) = ''
SELECT
#COLUMNLIST = #COLUMNLIST + QUOTENAME(NAME) + ','
FROM
sys.columns
WHERE
OBJECT_ID = OBJECT_ID('xp.XPROPERTYVALUES') AND
--COLUMN_ID NOT IN(1,2,3)
COLUMN_ID IN(452,453,454)
SELECT
#COLUMNLIST = LEFT(#COLUMNLIST,LEN(#COLUMNLIST)-1)
SET
#SQLSTRING =
'
SELECT
upv.id,
upv.item_id,
upv.itemtype_id,
upv.X_Category,
upv.X_Values
FROM
xp.XPROPERTYVALUES
UNPIVOT
(
X_Values FOR X_Category
IN
(' + #COLUMNLIST + ')
) AS upv
'
PRINT
(#SQLSTRING)
EXECUTE
sp_executesql #SQLSTRING
It just needs a source query.
And you can re-use the calculated column list for that.
DECLARE #SQLSTRING NVARCHAR(MAX),
#COLUMNLIST NVARCHAR(MAX);
DECLARE #TABLENAME VARCHAR(30) = 'xp.XPROPERTYVALUES';
SELECT #COLUMNLIST = CONCAT(#COLUMNLIST + ', ', QUOTENAME(NAME))
FROM sys.columns
WHERE OBJECT_ID = OBJECT_ID(#TABLENAME)
AND LOWER(NAME) NOT LIKE '%id';
SET #SQLSTRING = N'SELECT upv.id
, upv.item_id, upv.itemtype_id
, upv.X_Category, upv.X_Values
FROM
(
SELECT id, item_id, itemtype_id,
'+ #COLUMNLIST + N'
FROM '+ #TABLENAME +N'
) src
UNPIVOT
(
X_Values FOR X_Category IN (' + #COLUMNLIST + N')
) upv';
-- SELECT #SQLSTRING;
EXECUTE sp_executesql #SQLSTRING;

I am writing the following dynamic SQL, and getting an error in the PIVOT section of the View creation.
Incorrect syntax near ','
FOR [Accounts] IN (
' + #pivotColumns + '
I know why, its because there shouldn't be a comma that precedes the FIRST #pivotColumn (see image below for example). However, the column is a result of dynamic SQL, how do I go about resolving this? And I cant use trailing comma instead because then I will have a similar problem with the last column.
Basically, I need a way to make
SELECT #pivotColumns =....
not append a leading comma to the FIRST column/Account selected.
The comma is added at the end at this part of #pivotColumns:
',', quotename
Full Query:
DECLARE #sqlCommand NVARCHAR(MAX) = '',
#columnList NVARCHAR(MAX) = '',
#pivotColumns NVARCHAR(MAX) = '';
SELECT #columnList = STUFF(
(SELECT DISTINCT concat(CHAR(9), ',', 'COALESCE(', quotename(AccTbl.Account), ', 0)', quotename(AccTbl.Account), CHAR(10))
FROM [Accounts] AccTbl
--WHERE AccTbl.Active = 'YES'
WHERE AccTbl.Account NOT IN ('WS')
FOR XML Path(''), TYPE).value('(./text())[1]', 'NVARCHAR(MAX)'), 1, 1, '');
SELECT #pivotColumns = STUFF(
(SELECT DISTINCT concat(CHAR(9), ',', quotename(AccTbl.Account), CHAR(10))
FROM [Accounts] AccTbl
WHERE AccTbl.Account NOT IN ('WS')
FOR XML Path(''), TYPE).value('(./text())[1]', 'NVARCHAR(MAX)'), 1, 1, '');

In other words, whats happening right now is something like this:
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),

SET #col = substring(#col,1, len(#col))
set #query = '

)
SELECT '+#col+'

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 a shop order table with the Item code, description ReleaseDate and Required quantity.
How to query in a pivot table format in such a way that the results will be pivoted using Year+Month of [ReleaseDate] in sorting order from oldest date to latest date. Using the Year+Month as a column.
This is my query but it fails.
--Declare necessary variables
DECLARE #SQLQuery AS NVARCHAR(MAX)
DECLARE #PivotColumns AS NVARCHAR(MAX)
--Get unique values of pivot column
SELECT #PivotColumns = COALESCE(#PivotColumns + ',','') + QUOTENAME([YEARMONTH])
FROM (SELECT DISTINCT CONVERT(char(6), cast([releaseddate] as date), 112 ) as [YEARMONTH] FROM [dbo].[ShopOrder]) as PivotQuery
SELECT #PivotColumns
--Create the dynamic query with all the values for
--pivot column at runtime
SET #SQLQuery =
N'SELECT ItemCode, ' + #PivotColumns + '
FROM [dbo].[ShopOrder]
PIVOT( SUM(RequiredQty)
FOR [releaseddate] IN (' + #PivotColumns + ')) AS P'
SELECT #SQLQuery
--Execute dynamic query
EXEC sp_executesql #SQLQuery
This is the original record
Results query must be like this
Here I have tried to execute the pivot with your provided data.
Query
Select
[ItemCode],
[Description],
[2017/8],
[2017/9]
from
(
select cast(year(ReleasedDate) as nvarchar)+'/'+cast(month(ReleasedDate) as nvarchar) as ReleasedDate,ItemCode,Description,RequiredQty
from shoporder) as PivotData
Pivot
(
sum(RequiredQty) for ReleasedDate in
([2017/8],[2017/9])) as Pivoting
order by ItemCode
Output:
Fiddle
You are not pivoting correctly and the column names should be generated in a single string. Try this:
CREATE TABLE ShopOrder (ItemCode VARCHAR(100),[Description] VARCHAR(100),ReleaseDate DATE, RequiredQty INT)
GO
INSERT INTO ShopOrder
VALUES
('A','SLEEVE NUT','08/01/2017',19200)
,('A','SLEEVE NUT','08/02/2017',18000)
,('A','SLEEVE NUT','09/01/2017',17000)
,('B','STARTER','08/03/2017',10000)
,('B','STARTER','08/04/2017',18000)
,('B','STARTER','09/15/2017',16000)
