I'm working on pivot functionality.
I'm having 2 tables one is userinfo and another is hobbies.
My table will be as like below image.
I'm saving the hobbies with comma separated data in userinfo.
I want all the comma separated hobbies with their respective column names.
I tried, but getting indivdual records for each hobbies instead of the single row
as like below image.
My code is as follows :
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
--drop table Temptbl1
--drop table Temptbl2
IF EXISTS (SELECT * FROM Temptbl1)
drop table Temptbl1
IF EXISTS (SELECT * FROM Temptbl2)
drop table Temptbl2
SELECT * INTO Temptbl1 FROM UserInfo CROSS APPLY dbo.SplitData(Hobbies,',')
--select * from Temptbl1
Select * into Temptbl2 from Temptbl1 s,Hobbies h where s.DividedItem=h.Hid
--select * from Temptbl2
select #cols = STUFF((SELECT distinct ',' + QUOTENAME(HName) from Hobbies
FOR XML PATH(''), TYPE ).value('.', 'NVARCHAR(MAX)') ,1,1,'')
print #cols
set #query = 'SELECT distinct UId,UName,UAge,Hid, '+#cols +' from ( select
* from Temptbl2 )
x
pivot
(max(DividedItem) for HName in (' + #cols + ') ) p '
select * from Temptbl2
exec(#query)
You are selecting all columns from the temptbl2 and you do not need them. The Hid column is selected there and it is making the rows unique and the pivot fails to aggregate the results correctly. Just change it to this:
set #query = 'SELECT distinct UId,UName,UAge, '+#cols +' from ( select UId,UName,UAge, DividedItem, HName
from Temptbl2 )
x
pivot
(max(DividedItem) for HName in (' + #cols + ') ) p '
And you will be OK.
Here is full working example on SQL Server 2016 SP1. I am using string_split to split the data and temporary table to store it. Also, change a little bit the join syntax (your is obsolete and should not be used). You can adapt the code below to work on your environment easily:
DECLARE #hobbies TABLE
(
[HiD] INT
,[HName] VARCHAR(12)
);
INSERT INTO #hobbies ([HiD], [HName])
VALUES (1, 'Reading')
,(2, 'Singing')
,(3, 'Dancing');
DECLARE #UserInfo TABLE
(
[UID] INT
,[UName] VARCHAR(12)
,[UAddress] VARCHAR(12)
,[UAge] TINYINT
,[Hobbies] VARCHAR(12)
)
INSERT INTO #UserInfo ([UID], [UName], [UAddress], [UAge], [Hobbies])
VALUES (1, 'Abc', 'addr1', 25, '2,3')
,(2, 'Def', 'addr2', 27, '1,2,3')
,(3, 'Ghi', 'addr3', 20, '1');
DROP TABLE IF EXISTS #TEST;
SELECT *
INTO #TEST
FROM #UserInfo UI
CROSS APPLY string_split(UI.[Hobbies], ',') HS
INNER JOIN #hobbies H
ON HS.[value] = h.[HiD]
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX);
Select #cols = STUFF((SELECT distinct ',' + QUOTENAME(HName) from #hobbies
FOR XML PATH(''), TYPE ).value('.', 'NVARCHAR(MAX)') ,1,1,'')
set #query = 'SELECT distinct UId,UName,UAge, '+#cols +' from ( select uid, uname, uage, hname, value
from #TEST )
x
pivot
(max(value) for HName in (' + #cols + ') ) p '
exec(#query)

I have a simple table. As a result I need to get names of numeric columns and paste like rows and then paste its values like columns.Here is an example of table:
As a result I need to receive something like this:
I tried to get the result with PIVOT, but I have not the correct answer.
select * from (
select col1, 'val' + cast(row_number()over(partition by col1 order by col1) as nvarchar(20)) ColVal
from mytbl
) tmp
pivot (
min(col1) for ColVal in (val1,val2)
) pvt
In this case you need to unpivot first, then pivot back:
DROP TABLE IF EXISTS dbo.temp
DROP TABLE IF EXISTS dbo.temp2
CREATE table dbo.temp(col1 INT, col2 INT, col3 INT);
INSERT INTO temp VALUES (27,93,80),(32,84,72),(46,68,75),(38,79,73),(23,77,84);
DECLARE #colsUnpivot AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
-- first unpivot to key value pairs
select #colsUnpivot
= stuff((select ','+quotename(C.column_name)
from information_schema.columns as C
where C.table_name = 'temp' and
C.column_name like 'col%'
for xml path('')), 1, 1, '')
set #query
= 'SELECT ''val'' + convert(varchar, i) as id,
name,
val
INTO dbo.temp2
FROM
(
SELECT *, row_number() over (order by col1) as i
from temp
) a
UNPIVOT
(
val
FOR name IN ('+ #colsunpivot +')
) u'
exec sp_executesql #query;
-- now pivot back
DECLARE #columns NVARCHAR(MAX), #sql NVARCHAR(MAX);
SET #columns = N'';
SELECT #columns += N', ' + QUOTENAME(id)
FROM (SELECT DISTINCT id FROM dbo.temp2) AS x;
SET #query = N'
SELECT name, ' + STUFF(#columns, 1, 2, '') + '
FROM
(
SELECT id, name, val
from temp2
) AS j
PIVOT
(
SUM(val) FOR id IN ('
+ STUFF(REPLACE(#columns, ', [', ',['), 1, 1, '')
+ ')
) AS p;';
EXEC sp_executesql #query;
I adapted two separate scripts I had lying around, hence the two parts and the intermediate temp2 table. You can probably mash both together with a bit of elbow grease, but this should get you most of the way there.
Also adding the id (to get val1, val2 etc) dynamically means the results are sorted by col1 (val1 will have the lowest col1) but you were doing something similar in your attempt so I assume this is ok. If not, you will need to add an identity column to the data first and use that in place of the row_number()
hello friends i m trying to convert row Data with dates in column headers
this is my sql attendanceData Table
Normal Table
Original Data
and i want to convert row dates into column headers like this
Transpose
can someone tell me how i can do this in sql
i m sure using pivot i can,
so i tried sql query to pivot
SELECT Enterprise_ID, Date, Attendance
FROM attendanceData natural
join ( SELECT Enterprise_ID
FROM attendanceData
group BY Enterprise_ID
)
pivot (max(P) for Attendance in ('P' as P, 'WO' as WO)
I tried using dynamic pivot
Sample script to generate data:
create table #a
(
entrprise_id varchar(50),
datee date,
attendance varchar(10)
)
insert into #a values
('james','2018-12-22','p'),
('james','2018-12-23','p'),
('pick','2018-12-23','p'),
('rick','2018-12-23','p'),
('pick','2018-12-22','p'),
('rick','2018-12-22','p')
PIVOT Query:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX);
SET #cols = STUFF((SELECT distinct ',' + QUOTENAME(c.datee)
FROM #a c
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT entrprise_id, ' + #cols + ' from
(
select*
from #A
) x
pivot
(
max(attendance)
for datee in (' + #cols + ')
) p '
execute(#query)
or
select *
from
(
select *
from #A
) src
pivot
(
max(attendance)
for datee in ([2018-12-22], [2018-12-23])
) piv
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 created a query which returns me the following:
[Branch], [SaleDate], [ReceiptNo]
My [SaleDate] column is a concatenation of the SaleMonth and SaleYear in the format '01/2013'
What I require is these results to come out as a form of a table with:
A Column for each [SaleDate]
A Row for each [Branch]
The value for each Row/Column will be a COUNT([ReceiptNo])
Any pointers will be greatly appreciated.
Thanks in advance.
Use the PIVOT table operator:
SELECT *
FROM
(
SELECT ReceiptNo, SaleDate, Branch
FROM tablename
) AS t
PIVOT
(
COUNT(ReceiptNo)
FOR SaleDate IN([01/2013], [02/2013], [03/2013], ...)
) AS p;
SQL Fiddle Demo
To do this dynamically instead of listing the values of SaleDate manually, you have to use dynamic SQL, like this:
DECLARE #cols AS NVARCHAR(MAX);
DECLARE #query AS NVARCHAR(MAX);
select #cols = STUFF((SELECT distinct ',' +
QUOTENAME(SaleDate)
FROM tablename
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
, 1, 1, '');
SELECT #query = 'SELECT *
FROM
(
SELECT ReceiptNo, SaleDate, Branch
FROM tablename
) AS t
PIVOT
(
COUNT(ReceiptNo)
FOR SaleDate IN(' + #cols + ')) AS p;';
execute(#query);
Updated SQL Fiddle Demo
Is there a way to directly store the results of a dynamic pivot query into a fixed table? As the result is dynamic I can't create the table by specifying the columnnames and methods like "create table MyTable as (pivot select statement)" seem to fail on SQL server ("Incorrect syntax near the keyword 'AS'").
I have tried to format the SQL below to get a SELECT - INTO - FROM structure but failed to do so. Any help is obviously greatly appreciated!
The SQL used for the pivot is (build thanks to this great website!):
declare #pivot varchar(max), #sql varchar(max)
create table pivot_columns (pivot_column varchar(100))
insert into pivot_columns
select distinct DateField from MyTable order by 1
select #pivot=coalesce(#pivot+',','')+'['+pivot_column+']'from pivot_columns
set #sql = 'SELECT * FROM (select DateField, RefCode, SumField from MyTable) p
PIVOT
(sum(SumField) FOR DateField IN ( ' + #pivot + ') )
AS pvl'
drop table pivot_columns
exec (#sql)
Unless I am not following what you are trying to do you should be able to add the INTO mynewTable to your sql that you are going to execute and you should get the new table.
declare #pivot varchar(max), #sql varchar(max)
create table pivot_columns (pivot_column varchar(100))
insert into pivot_columns
select distinct DateField from MyTable order by 1
select #pivot=coalesce(#pivot+',','')+'['+pivot_column+']'from pivot_columns
set #sql = 'SELECT * INTO mynewTable FROM (select DateField, RefCode, SumField from MyTable) p
PIVOT
(sum(SumField) FOR DateField IN ( ' + #pivot + ') )
AS pvl'
drop table pivot_columns
exec (#sql)
I just test creating a new table in the following script and it gives me a new table that is in the DB for use:
create table t

[month] int,
[id] nvarchar(20),
[cnt] int
)
insert t values (4,'TOTAL',214)
insert t values (5,'TOTAL',23)
insert t values (6,'TOTAL',23)
insert t values (4,'FUNC',47)
insert t values (5,'FUNC',5)
insert t values (6,'FUNC',5)
insert t values (4,'INDIL',167)
insert t values (5,'INDIL',18)
insert t values (6,'INDIL',18)
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX);
select #cols = STUFF((SELECT distinct ',' + QUOTENAME(month)
FROM t
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT *
INTO tabletest from
(
select month, id, cnt
from t
) x
pivot
(
sum(cnt)
for month in (' + #cols + ')
) p '
execute(#query)
drop table t
