Trying to create a view with a PIVOT in it, can't figure out the syntax. The source view has three columns: ClientNameID, Item, and CountOfItem. I want ClientNameID to be the row, Item to be the column, and CountOfItem to be the value.
I figured it out:
SELECT clientnameid
FROM dbo.vAggregateSalesByCustomerAndItem
pivot (
Sum(countOfItem) FOR Item in ([Ring])
) PivotTable
The problem was syntax BUT I also learned that the dimensions (columns) must be hard-coded in the DML. I wanted to get the dimensions dynamically from a table, which is do-able in Excel, with a column range, but not here.
I think you should try this. its worked for you..
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT DISTINCT ',' + Item
from dbo.vAggregateSalesByCustomerAndItem
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT clientnameid ' + #cols + ' from
(
select clientnameid,countOfItem,Item
from dbo.vAggregateSalesByCustomerAndItem
) x
pivot
(
Sum(countOfItem)
for Item in (' + #cols + ')
) p '
execute(#query);

I'm developing a program where I have multiple columns which I need to show the sum of to anEnd-user. These columns are assigned in the table ColumnTest in the column ColumnNames and their names can be changed by the user. Therefore I need to look up all the column names in ColumnTest\ColumnNames and afterwards sum all values regarding these columnnames from the outputtable.
I have previously used this script where I get all the columnnames in #cols like this [col1].[col2].[col3] and so on, but when I try to run the query I'm not able to sum these columns using '+ #cols + '. When I run this I get the following error: The SUM function requires 1 argument(s). Is there a viable option to do this procedure, without compromising the loading-time substantially?
DECLARE
#cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX);
SELECT #cols = STUFF((SELECT distinct ',' + QUOTENAME(c.ColumnNames)
FROM ColumnTest c
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)') ,1,1,'')
set #query =
'
SELECT
ID
,SUM('+ #cols + ')
FROM Output_table
GROUP BY
ID
'
execute(#query);
Try this,
DECLARE
#cols AS NVARCHAR(MAX)='',
#query AS NVARCHAR(MAX);
SELECT #cols += 'SUM('+ColumnNames+') as ['+ColumnNames+'],'
from
(
SELECT distinct ColumnNames FROM ColumnTest
)A
SELECT #cols=LEFT(#cols,LEN(#cols)-1)
set #query =
'
SELECT ID,'+ #cols + '
FROM Output_table
GROUP BY ID
'
execute(#query);
or if you want addition of all column values you can use below query
DECLARE #cols AS NVARCHAR(MAX)='',
#query AS NVARCHAR(MAX);
SELECT #cols += ''+ColumnNames+'+'
FROM
(
SELECT DISTINCT ColumnNames FROM ColumnTest
)A
SELECT #cols=LEFT(#cols,LEN(#cols)-1)
set #query =
'
SELECT ID,SUM('+ #cols + ')
FROM Output_table
GROUP BY ID
'
execute(#query);
You can not use comma separated like ','
You can use '+'
Try this
DECLARE
#cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX);
SELECT #cols = STUFF((SELECT distinct '+' + QUOTENAME(c.ColumnNames)
FROM ColumnTest c
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)') ,1,1,'')
set #query =
'
SELECT
ID
,SUM('+ #cols + ')
FROM Output_table
GROUP BY
ID
'
execute(#query);
I'm using a pivot command and I've got it producing the desired output as written below:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SELECT Id, IssuedCN, [EmailAddress], [ServerHostName], [ManagerEmail]
FROM (SELECT Id, IssuedCN, StringValue, Name
FROM dbo.certmetadata) AS Source
PIVOT(
MAX(StringValue)
FOR Name IN ([EmailAddress], [ServerHostName], [ManagerEmail])
)
AS PvtTable_1;
But the pivoted table names are going to be user defined. The current ones, [EmailAddress] [ServerHostName] [ManagerEmail], will probably stay there but could be changed or even non-existent. The user defined names are stored in a table but I can't seem to figure out how, if possible, to bring them into the above code.
I'm using server 2012.
If that doesn't make sense let me know and I can try to provide more detail.
Thanks!
If you are going to have an unknown number of columns, then you will need to look at using dynamic SQL. The basic syntax will be similar to this:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
-- get the list of columns
-- apply a filter on the columns here if needed
select #cols = STUFF((SELECT ',' + QUOTENAME(Name)
from dbo.certmetadata
group by name
order by name
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT Id, IssuedCN,' + #cols + '
from
(
SELECT Id, IssuedCN, StringValue, Name
from dbo.certmetadata
) x
pivot
(
min(stringvalue)
for name in (' + #cols + ')
) p '
exec sp_executesql #query;
I am trying to pivot table DYNAMICALLY but couldn't get the desired result.
Here is the code to create a table
create table Report
(
deck char(3),
Jib_in float,
rev int,
rev_insight int,
jib_out float,
creation int
)
insert into Report values
('A_1',0.345,0,0,1.23,20140212),
('B_2',0.456,0,4,2.34,20140215),
('C_3',0.554,0,6,0.45,20140217),
('D_4',0.231,0,8,7.98,20140222),
('E_5',0.453,0,0,5.67,20140219),
('F_6',0.344,0,3,7.23,20140223)'
Code written so far.... this pivots the column deck and jib_in into rows but thats it only TWO ROWS i.e the one i put inside aggregate function under PIVOT function and one i put inside QUOTENAME()
DECLARE #columns NVARCHAR(MAX), #sql NVARCHAR(MAX);
SET #columns = N'';
SELECT #columns += N', p.' + QUOTENAME(deck)
FROM (SELECT p.deck FROM dbo.report AS p
GROUP BY p.deck) AS x;
SET #sql = N'
SELECT ' + STUFF(#columns, 1, 2, '') + '
FROM
(
SELECT p.deck, p.jib_in
FROM dbo.report AS p
) AS j
PIVOT
(
SUM(jib_in) FOR deck IN ('
+ STUFF(REPLACE(#columns, ', p.[', ',['), 1, 1, '')
+ ')
) AS p;';
PRINT #sql;
EXEC sp_executesql #sql;
I need all the columns to be pivoted and show on the pivoted table. any help would be appreciated. I am very new at dynamic pivot. I tried so many ways to add other columns but no avail!!
I know there are other ways please feel free to mention if there is any other way to get this right.
Please use this (If you are getting Collation issue, please change all the 3 INT datatypes):
STATIC code:
SELECT HEADER, [A_1],[B_2],[C_3],[D_4],[E_5],[F_6]
FROM
(SELECT DECK,HEADER, VALUE FROM REPORT
UNPIVOT
(
VALUE FOR HEADER IN ([JIB_IN],[REV],[REV_INSIGHT],[JIB_OUT],[CREATION])
) UNPIV
) SRC
PIVOT
(
SUM(VALUE)
FOR DECK IN ([A_1],[B_2],[C_3],[D_4],[E_5],[F_6])
) PIV
Using Dynamic SQL:
DECLARE #COLSUNPIVOT AS NVARCHAR(MAX),
#QUERY AS NVARCHAR(MAX),
#COLSPIVOT AS NVARCHAR(MAX)
SELECT #COLSUNPIVOT = STUFF((SELECT ','+QUOTENAME(C.NAME)
FROM SYS.COLUMNS AS C
WHERE C.OBJECT_ID = OBJECT_ID('REPORT') AND C.NAME <> 'DECK'
FOR XML PATH('')), 1, 1, '')
SELECT #COLSPIVOT = STUFF((SELECT ',' + QUOTENAME(DECK)
FROM REPORT T FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') ,1,1,'')
SET #QUERY
= 'SELECT HEADER, '+#COLSPIVOT+'
FROM
(
SELECT DECK,HEADER,VALUE FROM REPORT
UNPIVOT
(
VALUE FOR HEADER IN ('+#COLSUNPIVOT+')
) UNPIV
) SRC
PIVOT
(
SUM(VALUE)
FOR DECK IN ('+#COLSPIVOT+')
) PIV'
EXEC(#QUERY)
select *
from (
select vtid, convert(date, dtime) as Date from Transaction_tbl where locid = 5
) as vt
pivot (
count(vtid)
for vtid in (select vtid from VType_tbl)
) as pvt
while executing this query am getting error
Incorrect syntax near the keyword 'select'." and Incorrect syntax near
')'.
actually I have one more table,name= Vtype_table , How Can I load all vtid from vtype table in this query? I want to get output depend upon vtid.
Any help greatly appreciated.
Your PIVOT syntax is correct except you are using a SELECT statement inside your PIVOT.
You cannot use a SELECT statement inside the PIVOT IN clause to select column headers. It is required that the columns for the IN clause be known prior to executing the query.
If you are looking to generate a dynamic list of vtid values, then you will need to use dynamic SQL to get the result and the syntax will be similar to the following:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT distinct ',' + QUOTENAME(vtid)
from VType_tbl
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT Date, ' + #cols + '
from
(
select vtid, convert(date, dtime) as Date
from Transaction_tbl
where locid = 5
) d
pivot
(
count(vtid)
for vtid in (' + #cols + ')
) p '
execute(#query);
Edit, if you want the type names to appear then you should be able to use the following:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT distinct ',' + QUOTENAME(vt_name)
from VType_tbl
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT Date, ' + #cols + '
from
(
select v.vt_name, convert(date, dtime) as Date
from Transaction_tbl t
inner join VType_tbl v
on t.vtid = v.vtid
where locid = 5
) d
pivot
(
count(vt_name)
for vt_name in (' + #cols + ')
) p '
execute(#query)
Note: I am guessing on the column name for VType_tbl
This question already has answers here:
Get ROWS as COLUMNS (SQL Server dynamic PIVOT query)
(2 answers)
Closed 9 years ago.
I have the following basic SQL statement which uses the PIVOT command.
SELECT *
FROM
(
--select statement that creates my dataset
) s
PIVOT (Max(incidentcount) for dept in ([dept1],[dept2])) p
This does what I expect it to do, it gives me a count of incidents per reason with depts as my columns. My problem is the departments that I am using for my columns go from 1-60.
Is there anyway I can tell the query to use the column Department to populate the PIVOT in part. Obviously I want to avoid manually typing each department.
EDIT
This is the sql that creates my dataset that I use in the pivot...
SELECT Details, Department , count(*) NoIncidents
FROM myincidentdb
Group by Details, Department
EDIT 2
You will want to use dynamic sql to PIVOT this, your code will be similar to this:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT DISTINCT ',' + QUOTENAME(dept)
from yourtablewithDepartments
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT *
from
(
<your query goes here>
) src
pivot
(
max(incidentcount)
for dept in (' + #cols + ')
) piv '
execute(#query)
If you post more details like table structure, etc then this can be refined to meet your needs.
Edit, based on your current query, it looks like you can use the following:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX),
#colsNull AS NVARCHAR(MAX)
select #cols = STUFF((SELECT distinct ',' + QUOTENAME(department)
from myincidentdb
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT Details, ' + #cols + '
from
(
select Details, Department
from myincidentdb
) x
pivot
(
count(Department)
for Department in (' + #cols + ')
) p '
execute(#query)
