Create table on SQL Server from dynamic pivot results - sql-server

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

Update with order

I am building a dynamic SQL statement
This my code
declare #TmpDRGs varchar(max)
set #TmpDRGs = 'CREATE TABLE #TmpDRGs ( ur_number varchar(10) '
declare #Temp1 as table (diagnosis varchar(10))
insert into #Temp1 (diagnosis)
select DISTINCT diagnosis
from PtsDiagnosis
order by diagnosis
update #Temp1
set #TmpDRGs = #TmpDRGs + ',[' + diagnosis + '] tinyint'
select #TmpDRGs
The output is
CREATE TABLE #TmpDRGs ( ur_number varchar(10) ,[X90] tinyint,[N73] tinyint,[P84] tinyint,[B08]...
I want them to be in order like this
CREATE TABLE #TmpDRGs ( ur_number varchar(10) ,[B08] tinyint,[N73] tinyint,[P84] tinyint,[X90]...
I used order by in the building #Temp1 table but still getting them in wrong order
I cannot order by the update statement
so how to put these columns in order?
Try the following:
DECLARE #B VARCHAR(MAX) = 'CREATE TABLE #B ( ur_number varchar(10),'
SELECT #B += STUFF((SELECT DISTINCT ',['+ CAST(diagnosis AS VARCHAR) + '] tinyint'
FROM PtsDiagnosis
ORDER BY diagnosis
FOR XML PATH('')),1,1,'')+')'
PRINT(#B)

Pivot getting multiple records

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)

Rows to Columns RDLC

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)

Creatin tbale
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 :
https://msdn.microsoft.com/en-us/azure/data-lake-analytics/u-sql/pivot-and-unpivot-u-sql
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.

sql server 2008 pivot more than one column and dynamic column

I have two tables. I write a query. Date is dynamic. I can select any date. `
select a.MP,a.CP,a.Frequency,a.Time,CONVERT(varchar(12),b.date,101) as
EntryDate,b.actualtime from mpcp a, DailyData b
where a.UserID=1 and a.MpCpId=b.MpCpId and
CONVERT(varchar(12),b.EntryDate,101) between
CONVERT(varchar(12),GETDATE()-5,101) and
CONVERT(varchar(12),GETDATE()+25,101)`
Output
But i want output like
Assuming that i am storing your result in one temp table and imaging data i created one data for your requirement
try this one whether it is useful or not
create table #piv
(
mp varchar(10),
cp varchar(10),
freq varchar(10),
time int,
entryd date,
acuralize int
)
insert into #piv values
('don','asper','da',30,getdate(),0),
('dwm','donl','da',10,getdate(),3),
('qar','qpr','da',15,getdate(),5),
('qar','qpr','da',15,'01-16-17',5),
('qar','qpr','da',15,'01-15-17',5),
('qar','qpr','da',15,'01-16-17',5)
SELECT * FROM #piv
Declare #SQL varchar(max) = Stuff((Select Distinct ',' + QuoteName(entryd) From #piv Order by 1 For XML Path('')),1,1,'')
Select #SQL = '
Select *,' + #SQL + '
From #piv
Pivot (max(time) For [entryd] in (' + #SQL + ') ) p'
Exec(#SQL);
You can create a dynamic pivot. A good example is available on this link.
Good Luck !
DECLARE #cols VARCHAR(max),#sql VARCHAR(max)
SELECT #cols=ISNULL(#cols+',[','[')+ CONVERT(VARCHAR,a.EntryDate,101)+']'

GROUP BY a.time
SET #sql='
SELECT * FROM (
SELECT a.MP,a.CP,a.Frequency,a.Time,CONVERT(varchar(12),b.date,101) AS EntryDate,b.actualtime

Showing "Invalid object name " in sqlServer?

While Executing the Following query it showing the Invalid object name '#temp1'. can any body knows the error occurred due to which reason this is my orginal code i used to fetch code , her differnt tables are formed i need to get the sum of the each row of each table
DECLARE #t TABLE (
id int IDENTITY(1,1),
BranchName nvarchar(max)
)
DECLARE #n int = 0,
#i int = 1,
#BranchName nvarchar(max),
#sql nvarchar(max),
#columns nvarchar(max)
INSERT INTO #t
SELECT DISTINCT BranchName
FROM ALX_Branches
SELECT #n = ##ROWCOUNT
WHILE #n >= #i
BEGIN
SELECT #BranchName = BranchName
FROM #t
WHERE id = #i
SELECT #columns = (
SELECT DISTINCT ','+QUOTENAME([SubInventory])
FROM #MyTempTable
WHERE [BranchName] = #BranchName
FOR XML PATH('')
)
SELECT #sql = N'--
SELECT * into #temp1
FROM (
SELECT [BranchID],
[SubInventory],
[Product],
[Stock]
FROM #MyTempTable
WHERE [BranchName] = ''' +#BranchName +'''
) as t
PIVOT (
MAX([Stock]) FOR [SubInventory] IN ('+STUFF(#columns,1,1,'')+')
) as pvt'
EXEC sp_executesql #sql
select * from #temp1
Firstly, there is no need for creating #temp1 table before.
because you are using "Select * into" that already create table within it.
Suppose type this note as a comment, but I don't have enough reputation score.
The reason of
Invalid object name '#temp1'
is: the variable #sql is NULL because #temp1 is not created yet via "Select * into" clause.
so append selecting from #temp1 within dynamic sql as the following:
SELECT #sql = N'--
SELECT * into #temp1
FROM (
SELECT [BranchID],
[SubInventory],
[Product],
[Stock]
FROM #MyTempTable
WHERE [BranchName] = ''' +#BranchName +'''
) as t
PIVOT (
MAX([Stock]) FOR [SubInventory] IN ('+STUFF(#columns,1,1,'')+')
) as pvt
select * from #temp1 '
EXEC sp_executesql #sql
