I'm trying to sort some shipment data using a SQL Pivot but i can not figure it out.
I've the data sorted in this way (one row with the total items shipped for a family for each month of each year starting from 2015 to ):
TABLE A
Year | Month | ItemFamilyCode | TotalShipped
2018 | 9 | FA01 | 5
2018 | 9 | FA04 | 4
2018 | 10 | FA01 | 2
2018 | 11 | FA02 | 1
2018 | 12 | FA03 | 3
2019 | 1 | FA04 | 7
and so on. I want to achieve the following result:
ItemFamilyCode | 2018-9 | 2018-10 | 2018-11 | 2018-12 | 2019-1 | [..]
FA01 | 5 | 2 | 0 | 0 | 0 |
FA02 | 0 | 0 | 1 | 0 | 0 |
FA03 | 0 | 0 | 0 | 3 | 0 |
FA04 | 4 | 0 | 1 | 0 | 7 |
and so on ... the family code in order and all the values for each month of each year, from the older month/year to now. Is it possible? Thanks to anyone who can help.
If you want to use it as view :
SELECT * FROM
(
SELECT
Concat([Year],'-', [Month]) as [Date],
ItemFamilyCode,
TotalShipped
FROM Shipping -- Or any Table Name
) t
PIVOT(
Sum(TotalShipped)
FOR [Date] IN (
[2018-9],
[2018-10],
[2018-11],
[2018-12],
[2019-1],
[2019-2] -- You have to type all months until today
)
) AS pivot_table;
And, dynamic sql if you can use it in stored procedure :
Make a table with the content of date list to generate date list string
DECLARE
#columns NVARCHAR(MAX) = '',
#sql NVARCHAR(MAX) = '';
-- select the category names
SELECT
#columns+=QUOTENAME(Date) + ','
FROM
DateList
ORDER BY
DateList;
-- remove the last comma
SET #columns = LEFT(#columns, LEN(#columns) - 1);
-- construct dynamic SQL
SET #sql ='
SELECT * FROM
(
SELECT
Concat([Year],'-', [Month]) as [Date],
ItemFamilyCode,
TotalShipped
FROM Shipping -- Or any Table Name
) t
PIVOT(
Sum(TotalShipped)
FOR [Date] IN ('+ #columns +')
) AS pivot_table;';
-- execute the dynamic SQL
EXECUTE sp_executesql #sql;

From the answer from here I build a solution that is good for me but I have still one problem.
I had table:
ID | Year | Month | Multiply | Future | Current
123 | 2017 | 1 | 1.0 | 25 | null
123 | 2017 | 2 | 1.0 | 19 | 15
123 | 2017 | 3 | 1.0 | 13 | 0
123 | 2017 | 4 | 1.0 | 22 | 14
123 | 2017 | 5 | 1.0 | 13 | null
... | .... | ... | ... | .. | ..
123 | 2018 | 1 | 1.0 | 25 | 10
123 | 2018 | 2 | 1.0 | 25 | 10
... | .... | ... | ... | .. | ..
124 | 2017 | 1 | 1 | 10 | 5
124 | 2017 | 2 | 1 | 15 | 2
... | .... | ... | ... | .. | ..
124 | 2018 | 1 | 1 | 20 | 0
I build this view to concatenate Year + Month and make IF statement:
value in the new Value column I'm getting from Future and Current column - when the Current value is null get the Future value and multiply by Multiply, else get Current value and multiply by Multiply (even 0). Next to it I need to add a 'F' prefix when the value is got from Future column.
ID | Date | Value |
123 | 2017 - 1 | F25 |
123 | 2017 - 2 | 15 |
123 | 2017 - 3 | 0 |
.. | .. | .. |
Code for it:
SELECT ID = ID,
[Date] = [Date],
[Value] = [Value]
FROM ( SELECT ID,
cast([Year] as varchar(30)) + ' - ' + cast([Month]as varchar(30)) as [Date],
[Multiply],
case when [Current] IS NULL /*OR [Current] = 0*/
then 'F' + CAST([Future] * [Multiply] as varchar(30))
else CAST([Current] * [Multiply] as varchar(30))
end as Value
FROM dbo.CurrentFuture
) AS t
And from this I make this view via dynamically pivot.
ID | 2017 - 1 | 2017 - 10 | 2017 - 11 | 2017 - 12 | 2017 - 2 | ... | 2018 - 1 | ...
123 | F25 | .. | .. | .. | 15 | ... | 10 | ...
124 | 5 | 2 | .. | .. | .. | ... | 0 | ...
Code for it:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME([Date])
from dbo.UpperView
group by [Date]
order by [Date]
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT [ID],' + #cols + ' from
(
select [ID], [Date],[Value]
from [dbo].[UpperView]
) x
pivot
(
max([Value])
for [Date] in (' + #cols + ')
) p '
execute(#query);
As you can see columns in the new view are not sorting in a good way.. instead of 2017 - 1, 2017 - 2, 2017 - 3 I have 2017 - 1, 2017 - 10, 2017 - 11, 2017 - 12, 2017 - 2. Can you help me how to sort it properly?
From the limited information, What you want is the ordering of the column based on the Concatenated string of Year+ Month.
What you need is to prefix the month with "0" for January - September and no prefix for October-December.
so in effect you will achieve this.
ID | 2017 - 01 | 2017 - 02 | 2017 - 03 | ..... | 2017 - 09 |2018 - 10 |2018 - 11||2018 - 12|
SELECT ID = ID,
[Date] = [Date],
[Value] = [Value]
FROM
(
SELECT ID,
CAST([Year] AS VARCHAR(30))+' - '+RIGHT('0'+CAST([Month] AS VARCHAR(30)), 2) AS [Date],
[Multiply],
CASE
WHEN [Current] IS NULL
/*OR [Current] = 0*/
THEN 'F'+CAST([Future] * [Multiply] AS VARCHAR(30))
ELSE CAST([Current] * [Multiply] AS VARCHAR(30))
END AS Value
FROM dbo.CurrentFuture
) AS t;
Add new column to UpperView for sorting like this
cast([Year] as varchar(30)) + RIGHT('0' + cast([Month] as varchar(30)), 2) as [DateOrder]
and use this column for sorting at your column query instead of [Date]
select #cols = STUFF((SELECT ',' + QUOTENAME([Date])
from dbo.UpperView
group by [Date], [DateOrder]
order by [DateOrder]
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
I have a table like follows, i need to pivot the table with weeks. i could able to create pivot table but the columns order getting shuffled since im ordering a string column. and getting output like 3nd table.
MRN Weeks
--------------------------------
GIRFTR1H0461081 52
GIRFTR1H0461083 5 - 6
GIRFTR1H0461084 0 - 1
GIRFTR1H0461085 1 - 2
GIRFTR1H0461086 11 - 12
GIRFTR1H0461087 1 - 2
I need to get output as a pivot table order by Weeks Like,
MRN | 0 - 1 | 1 - 2 | 5 - 6 |11 - 12| 52
---------------------------------------------------------------
GIRFTR1H0461081 | 0 | 0 | 0 | 0 | 0
GIRFTR1H0461083 | 0 | 0 | 1 | 0 | 0
GIRFTR1H0461084 | 1 | 0 | 0 | 0 | 0
GIRFTR1H0461085 | 0 | 1 | 0 | 0 | 0
GIRFTR1H0461086 | 0 | 0 | 0 | 1 | 0
GIRFTR1H0461087 0 | 1 | 0 | 0 | 0
When i tried to create this table, the columns order getting shuffled like bellow,
MRN | 0 - 1 | 1 - 2 |11 - 12| 5 - 6 | 52
---------------------------------------------------------------
GIRFTR1H0461081 | 0 | 0 | 0 | 0 | 0
GIRFTR1H0461083 | 0 | 0 | 0 | 1 | 0
GIRFTR1H0461084 | 1 | 0 | 0 | 0 | 0
GIRFTR1H0461085 | 0 | 1 | 0 | 0 | 0
GIRFTR1H0461086 | 0 | 0 | 1 | 0 | 0
GIRFTR1H0461087 | 0 | 1 | 0 | 0 | 0
My code is,
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME(WeeksBand)
from [test_Tbl]
group by WeeksBand
order by WeeksBand
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT CurrentSpecialty,' + #cols + ' from
(
select CurrentSpecialty, WeeksBand, EncounterId
from [Tbl_Current_PTL_Test]
) x
pivot
(
count(EncounterId)
for WeeksBand in (' + #cols + ')
) p '
execute(#query);
Please help me to sort out my issue,
It's doing a string (alpha) sort, and you actually want to be doing a numeric sort.
I'd change the order line from:
order by WeeksBand
to:
order by Cast(SubString(WeeksBand, 1, CASE WHEN CHARINDEX('-', WeeksBand) != 0 THEN CHARINDEX('-', WeeksBand) -1 ELSE LEN(WeeksBand) END) AS INT)
which will convert the first number into an integer value (not string) and then should order correctly.
I don't see why a standard pivot query should not work here. From your expected output it seems you want a 1 as a placeholder for an MRN entry which is present in that week, and 0 otherwise.
SELECT [MRN],
MAX(CASE WHEN [Weeks] = '0 - 1' THEN 1 ELSE 0 END) AS [0 - 1],
MAX(CASE WHEN [Weeks] = '1 - 2' THEN 1 ELSE 0 END) AS [1 - 2],
MAX(CASE WHEN [Weeks] = '5 - 6' THEN 1 ELSE 0 END) AS [5 - 6],
MAX(CASE WHEN [Weeks] = '11 - 12' THEN 1 ELSE 0 END) AS [11 - 12],
MAX(CASE WHEN [Weeks] = '52' THEN 1 ELSE 0 END) AS [52]
FROM [yourTable]
GROUP BY [MRN]
You should format Week field of first table using 2 digits as:
MRN Weeks

My Query:
SELECT i.item_ID,
COUNT(CASE WHEN i.inc_cat_id = ic.inc_cat_id AND i.inc_cat_id = 1 THEN 1 END) AS cntSupport,
COUNT(CASE WHEN i.inc_cat_id = ic.inc_cat_id AND i.inc_cat_id = 2 THEN 1 END) AS cntPM,
COUNT(CASE WHEN i.inc_cat_id = ic.inc_cat_id AND i.inc_cat_id = 3 THEN 1 END) AS cntInstallation
FROM #incident i
CROSS APPLY #incCat ic
WHERE (i.date_logged BETWEEN '2016-04-01' AND '2016-04-30')AND i.cust_id='34'
GROUP BY i.item_ID
You don't need a CROSS APPLY. A simple LEFT JOIN will do:
SELECT i.item_id,
COUNT(CASE WHEN inc.inc_cat_id = 1 THEN 1 END) AS cntSupport,
COUNT(CASE WHEN inc.inc_cat_id = 2 THEN 1 END) AS cntPM,
COUNT(CASE WHEN inc.inc_cat_id = 3 THEN 1 END) AS cntInstallation
FROM Item AS i
LEFT JOIN Incident AS inc ON i.item_id = inc.item_id AND
inc.date_logged BETWEEN '2016-04-01' AND '2016-04-30'
WHERE i.cust_id = 34
GROUP BY i.item_id
You just need to start by table Item, so as to get all items returned, as in the expected result set in the OP.
Demo here
Unless I'm missing something, your query is over complicated:
SELECT item_ID,
COUNT(CASE WHEN .inc_cat_id = 1 THEN 1 END) AS cntSupport,
COUNT(CASE WHEN inc_cat_id = 2 THEN 1 END) AS cntPM,
COUNT(CASE WHEN inc_cat_id = 3 THEN 1 END) AS cntInstallation
FROM #incident
GROUP BY item_ID
UPDATE:
With the addition of logged_date column, you just need to add it in the ON clause. You need to use sp_executesql instead of EXEC now to prevent sql injection:
DECLARE #fromDate DATE = '2016-04-01',
#toDate DATE = '2016-04-30';
DECLARE #sql NVARCHAR(MAX) = N'';
SELECT #sql =
'SELECT
i.item_id' + CHAR(10) +
(SELECT
' , COUNT(CASE WHEN inc.inc_cat_id = ' + CONVERT(VARCHAR(10), inc_cat_id) +
' THEN 1 END) AS ' + QUOTENAME('count(' + inc_cat_n + ')') + CHAR(10)
FROM #Inc_cat
ORDER BY inc_cat_id
FOR XML PATH('')
) +
'FROM #item AS i
LEFT JOIN #incident AS inc
ON i.item_id = inc.item_id
AND inc.date_logged BETWEEN #fromDate AND #toDate
GROUP BY i.item_id;';
PRINT (#sql);
EXEC sp_executesql
#sql,
N'#fromDate DATE, #toDate DATE',
#fromDate,
#toDate

Giorgos answer is good if you only have that 3 Inc_cats. However, if you have unknown number of Inc_cats, you need to do it dynamically. Here is a method using a dynamic crosstab:
DECLARE #sql NVARCHAR(MAX) = N'';
SELECT #sql =
'SELECT
i.item_id' + CHAR(10) +
(SELECT
' , COUNT(CASE WHEN inc.inc_cat_id = ' + CONVERT(VARCHAR(10), inc_cat_id) +
' THEN 1 END) AS ' + QUOTENAME('count(' + inc_cat_n + ')') + CHAR(10)
FROM Inc_cat
ORDER BY inc_cat_id
FOR XML PATH('')
) +
'FROM Item AS i
LEFT JOIN Incident AS inc
ON i.item_id = inc.item_id
GROUP BY i.item_id;';
PRINT (#sql);
EXEC (#sql);
ONLINE DEMO
Basically, it's just a dynamic version of Giorgos' answer.
Hi I have a query that gets the total count of incidents per month and year
I wanted a result that shows all distinct years in columns
Could you please advise how to make this query dynamic?
Expected Result:
Month 2013 2014 2015
January 8 0 12
February 9 6 10
March 12 1 9
April 10 13 27
May 9 22 15
June 27 4 20
July 15 12 22
August 20 2 2
September 22 5 10
October 10 8 12
November 0 7 0
December 0 15 0
Query
select DATENAME(MONTH,DateOpened) as Month,
sum(case when year(DateOpened) = '2015' then 1 else 0 end) as [2015],
sum(case when year(DateOpened) = '2014' then 1 else 0 end) as [2014]
from Incidents
group by DATENAME(MONTH,DateOpened), MONTH(DateOpened)
order by MONTH(DateOpened)
Thanks for your help!
You can use the PIVOT table operator instead, something like this:
SELECT *
FROM
(
SELECT
DATENAME(MONTH,DateOpened) as Month,
DATENAME(Year,DateOpened) AS Year,
DateOpened
FROM Incidents
) AS t
PIVOT
(
COUNT(DateOpened)
FOR Year IN([2013], [2014], [2015])
) AS p;
SQL Fiddle Demo
If you don't need to write the list of years and do it dynamically for any year, you have to use dynamic SQL to run the query dynamically, like this:
DECLARE #cols AS NVARCHAR(MAX);
DECLARE #query AS NVARCHAR(MAX);
SELECT #cols = STUFF((SELECT distinct ',' +
QUOTENAME(DATENAME(Year,DateOpened))
from Incidents AS t
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
, 1, 1, '');
SELECT #query = 'SELECT * , '+ #cols + '
FROM
(
select
DATENAME(MONTH,DateOpened) as Month,
DATENAME(Year,DateOpened) AS Year,
DateOpened
FROM Incidents
) AS t
PIVOT
(
COUNT(DateOpened)
FOR Year IN(' + #cols + ')' +
') p';
execute(#query);
SQL Fiddle Demo
This will give you something like this:
| Month | 2014 | 2015 | 2014 | 2015 |
|-----------|------|------|------|------|
| April | 0 | 3 | 0 | 3 |
| August | 1 | 1 | 1 | 1 |
| December | 1 | 0 | 1 | 0 |
| February | 0 | 1 | 0 | 1 |
| July | 1 | 1 | 1 | 1 |
| September | 1 | 0 | 1 | 0 |
Note that: Both the queries won't list any month that has no dates on the original table. If you want to list any month that is not listed on the table with counts 0, you have to modify the anchor query so that it lists all the months even if not listed:
SELECT
m.Name as Month,
i.Year,
i.DateOpened
FROM
(
VALUES ('Janurary'), ('February'), ('March'),
('April'), ('May'), ('June'),
('July'), ('August'), ('September'),
('October'), ('November'), ('December')
) AS m(Name)
LEFT JOIN
(
SELECT
DATENAME(MONTH,DateOpened) as Month,
DATENAME(Year,DateOpened) AS Year,
DateOpened
FROM Incidents
) AS i ON i.Month = m.Name
and replace it in the dynamic query.
Updated SQL Fiddle
This will give you the missing months with zeros results:
| Month | 2014 | 2015 | 2014 | 2015 |
|-----------|------|------|------|------|
| Janurary | 0 | 0 | 0 | 0 | <<
| February | 0 | 1 | 0 | 1 |
| March | 0 | 0 | 0 | 0 | <<
| April | 0 | 3 | 0 | 3 |
| May | 0 | 0 | 0 | 0 | <<
| June | 0 | 0 | 0 | 0 | <<
| July | 1 | 1 | 1 | 1 |
| August | 1 | 1 | 1 | 1 |
| September | 1 | 0 | 1 | 0 |
| October | 0 | 0 | 0 | 0 | <<
| November | 0 | 0 | 0 | 0 | <<
| December | 1 | 0 | 1 | 0 |
A simple create table something like this..
CREATE TABLE #tmpIncidents
(
IncidentName NVARCHAR(50)
, DateOpened DATETIME
)
INSERT INTO #tmpIncidents (IncidentName,DateOpened) VALUES
('Test1',GETDATE()),
('Test1',DATEADD(YEAR,-1,GETDATE())),
('Test1',DATEADD(YEAR,-2,GETDATE())),
('Test1',DATEADD(YEAR,2,GETDATE())),
('Test1',DATEADD(YEAR,1,GETDATE())),
('Test1',DATEADD(YEAR,3,GETDATE()))
Then a build up query for multiple years
DECLARE #columnVar NVARCHAR(4000)
SELECT #columnVar =
(SELECT DISTINCT
'[' + CONVERT(NVARCHAR(150),DATEPART(YEAR,DateOpened)) + '],' AS [text()]
FROM #tmpIncidents
FOR XML PATH('')
)
SET #columnVar = (SELECT LEFT(#columnVar,LEN(#columnVar)-1))
--SELECT #columnVar --so you can see how it looks..
Then execute your query.
EXEC ('
SELECT
pv.*
FROM
(
SELECT DATENAME(MONTH,DateOpened) AS [DateName], DATEPART(YEAR,DateOpened) AS [YEAR], IncidentName FROM #tmpIncidents
) src
PIVOT
(
COUNT(IncidentName)
FOR [YEAR] IN (' + #columnVar + ')
) pv;
')
