Adding column totals to existing pivot with row totals

I previously received help on this query.  Now I have been asked to also have a total for each column.

SELECT *,
       isnull([January], 0)
	    + isnull([February], 0)
		 + isnull([March], 0)
		  + isnull([April], 0)
		   + isnull([May], 0)
		    + isnull([June], 0)
			 + isnull([July], 0)
			  + isnull([August], 0)
			   + isnull([September], 0)
			    + isnull([October], 0)
				 + isnull([November], 0)
				  + isnull([December], 0) AS Total
FROM
(
    SELECT PrimaryUnit,
           DATENAME(MONTH, ReportedDate) [Month],
           1 AS [CaseID]
    FROM Casemaster
    WHERE --Agency = 1
          --AND
		   ReportedDate BETWEEN '01-01-2017 00:00:00' AND '12-31-2017 23:59:59'
) src PIVOT(SUM([CaseID]) FOR Month IN([January],
                                       [February],
                                       [March],
                                       [April],
                                       [May],
                                       [June],
                                       [July],
                                       [August],

									   ) AS PrimaryUnitPivot
ORDER BY PrimaryUnit;

Theres a couple of ways to achieve TOTALS...

First is a bit of a cheat -  but legit - just repeat the query with a union all. For example

Select *, isnull([January],0)+isnull([February],0)+isnull([March],0)+isnull([April],0)+isnull([May],0)+isnull([June],0)+isnull([July],0)+isnull([August],0)+isnull([September],0)+isnull([October],0)+isnull([November],0)+isnull([December],0) as Total
From 
( Select 0 as seq, PrimaryUnit, DATENAME(MONTH, ReportedDate) [Month], 1 as [CaseID]
  From Casemaster
  Where Agency = 1
  and Year(ReportedDate) = 2017) src 
PIVOT
( SUM([CaseID])  FOR Month IN ([January],[February],[March],[April],[May],[June],[July],[August],[September],[October],[November],[December])) AS PrimaryUnitPivot

union all

Select *, isnull([January],0)+isnull([February],0)+isnull([March],0)+isnull([April],0)+isnull([May],0)+isnull([June],0)+isnull([July],0)+isnull([August],0)+isnull([September],0)+isnull([October],0)+isnull([November],0)+isnull([December],0) as Total
From 
( Select 1 as seq, ' ' as PrimaryUnit, DATENAME(MONTH, ReportedDate) [Month], 1 as [CaseID]
  From Casemaster
  Where Agency = 1
  and Year(ReportedDate) = 2017) src 
PIVOT
( SUM([CaseID])  FOR Month IN ([January],[February],[March],[April],[May],[June],[July],[August],[September],[October],[November],[December])) AS PrimaryUnitPivot

Order By seq,PrimaryUnit

Open in new window

Now, the obvious downside is have the SEQ column visible, and there are NULL's in the detail

Which means we need to fix that by NOT doing a SELECT *

And we have to do the hard yards now with spelling out columns - as a part example
Select PrimaryUnit
,isnull([January],0) as [January],isnull([February],0) as [February],isnull([March],0) as [March],isnull([April],0) as [April],isnull([May],0) as [may],isnull([June],0) as [June]
,isnull([July],0) as [July],isnull([August],0) as [August], isnull([September],0) as [Septembe],isnull([October],0) as [October],isnull([November],0) as [November],isnull([December],0) as [December]
,isnull([January],0)+isnull([February],0)+isnull([March],0)+isnull([April],0)+isnull([May],0)+isnull([June],0)+isnull([July],0)+isnull([August],0)+isnull([September],0)+isnull([October],0)+isnull([November],0)+isnull([December],0) as Total
From 
( Select 0 as seq, PrimaryUnit, DATENAME(MONTH, ReportedDate) [Month], 1 as [CaseID]
  From Casemaster
  Where Agency = 1
  and Year(ReportedDate) = 2017) src 
PIVOT
( SUM([CaseID])  FOR Month IN ([January],[February],[March],[April],[May],[June],[July],[August],[September],[October],[November],[December])) AS PrimaryUnitPivot

Order By seq,PrimaryUnit

Open in new window

But since we have done that, we may as well go the extra step and use the preferred method of GROUP BY
Select isnull(PrimaryUnit,'TOTAL') primaryunit
,SUM(isnull([January],0)) as [January],SUM(isnull([February],0)) as [February],SUM(isnull([March],0)) as [March],SUM(isnull([April],0)) as [April],SUM(isnull([May],0)) as [may],SUM(isnull([June],0)) as [June]
,SUM(isnull([July],0)) as [July],SUM(isnull([August],0)) as [August], SUM(isnull([September],0)) as [Septembe],SUM(isnull([October],0)) as [October],SUM(isnull([November],0)) as [November],SUM(isnull([December],0)) as [December]
,SUM(isnull([January],0)+isnull([February],0)+isnull([March],0)+isnull([April],0)+isnull([May],0)+isnull([June],0)+isnull([July],0)+isnull([August],0)+isnull([September],0)+isnull([October],0)+isnull([November],0)+isnull([December],0)) as Total
From 
( Select PrimaryUnit, DATENAME(MONTH, ReportedDate) [Month], 1 as [CaseID]
  From Casemaster
  Where Agency = 1
  and PrimaryUnit is not NULL
  and Year(ReportedDate) = 2017) src 
PIVOT
( SUM([CaseID])  FOR Month IN ([January],[February],[March],[April],[May],[June],[July],[August],[September],[October],[November],[December])) AS PrimaryUnitPivot
GROUP BY GROUPING SETS ( PrimaryUnit, () );--group by rollup(primaryunit)

Open in new window

And that is probably the best approach - dont cut corners, do the hard work of typing - or in my case - precoded examples using monthnames :)

And a worthy addition to https://www.experts-exchange.com/articles/653/Dynamic-Pivot-Procedure-for-SQL-Server.html

Is there a way to provide a label for the blank cell under primary unit.  I know this happens because no PrimaryUnit is assigned to the call as it was handled within the communications room.  I think this would prevent any questions about why no unit was listed.

Yep, look at the last code block....

And also try it without an ORDER BY....

In that last code block I used grouping sets, and could be a simple group by - the grouping sets () or rollup is what gives you the total

Sorry Mark but I just don't see it.

First line of last code block : Select isnull(PrimaryUnit,'TOTAL') primaryunit

and to make sure there is no chance of erroneous values, I also had : and PrimaryUnit is not NULL
in the WHERE clause os selecting the initial set of data (line 9 of the last code block)

OR....

If usting the "union all" approach, instead of ' ' as PrimaryUnit, use 'TOTAL' as PrimaryUnit,

AND ....

Pretty sure you do not need an ORDER BY - the pivot should return the data in PrimaryUnit order anyway.- which means the total willl be at the bottom

I've tried this but it just displayed a new column.

SELECT isnull(PrimaryUnit, 'TOTAL') as 'Un-Assigned', Primaryunit,

I should also indicate that the PrimaryUnit field will never be null but have a blank value if that makes any difference.

Mark WillsTopic AdvisorCommented:
Well, yes, you are adding a new column named Un-Assigned

Well, if PrimaryUnit can never be NULL otherwise, then just use that column

SELECT isnull(PrimaryUnit, 'TOTAL') as Primaryunit,

is a re-use of that same column - it will have either the value of PrimaryUnit or the word TOTAL

Because the ROLLUP or GROUPING SETS will create an additional row but with NULL in the column used in the group by definition.

Have a read of : https://docs.microsoft.com/en-us/sql/t-sql/queries/select-group-by-transact-sql?view=sql-server-2017#group-by-rollup and scroll down a bit to see the grouping sets.

Did you try that last code block in my original post - using the group by ?

Or are you using the UNION ALL example ?

MikeM670Author Commented:
I used the code block from the original post.

MikeM670Author Commented:
I've decided to leave well enough alone as I can't figure out how to add the label for any PrimaryUnits that were not assigned to clear up any confusion.

Mark WillsTopic AdvisorCommented:
Oh, sorry, I thought you were talking about getting the "TOTAL" being displayed, but, you are talking about the datasource....

So, in the

SELECT <results>
FROM
( <datasource> ) src
PIVOT
( aggregation for data-item in (<columnlist>)) pvt

In <datasource> where you select PrimaryUnit that is where you would need to take care of any substitution

If PrimaryUnit could be blank, or even NULL, then the best way to accommodate a default value of 'Unassigned' is to check the length

e.g

instead of just having the column PrimaryUnit, you can do:

IIF(len(trim(primaryUnit)) > 0, PrimaryUnit, 'Unassigned') as PrimaryUnit

Basically what that does is "If the trimmed length of PrimaryUnit is 1 or more characters long, then use that value, else use 'Unassigned' as the value for PrimaryUnit"

The challenge with T-SQL is deciding which way works best for you.... For example, prior to sql2017, (trim() from 2017, IIF() from 2012) to do the same as the IIF() above, we would have done :

CASE WHEN LEN(lltrim(rtrim(isnull(PrimaryUnit,'')))) > 0 then primaryUnit else 'Unassigned' end as PrimaryUnit

So, in the code block :
Select isnull(PrimaryUnit,'TOTAL') primaryunit
,SUM(isnull([January],0)) as [January],SUM(isnull([February],0)) as [February],SUM(isnull([March],0)) as [March],SUM(isnull([April],0)) as [April],SUM(isnull([May],0)) as [may],SUM(isnull([June],0)) as [June]
,SUM(isnull([July],0)) as [July],SUM(isnull([August],0)) as [August], SUM(isnull([September],0)) as [September],SUM(isnull([October],0)) as [October],SUM(isnull([November],0)) as [November],SUM(isnull([December],0)) as [December]
,SUM(isnull([January],0)+isnull([February],0)+isnull([March],0)+isnull([April],0)+isnull([May],0)+isnull([June],0)+isnull([July],0)+isnull([August],0)+isnull([September],0)+isnull([October],0)+isnull([November],0)+isnull([December],0)) as Total
From 
( Select IIF(len(rtrim(primaryUnit)) > 0, PrimaryUnit, 'Unassigned') as PrimaryUnit, DATENAME(MONTH, ReportedDate) [Month], 1 as [CaseID]
  From Casemaster
  Where Agency = 1
  and PrimaryUnit is not NULL
  and Year(ReportedDate) = 2017) src 
PIVOT
( SUM([CaseID])  FOR Month IN ([January],[February],[March],[April],[May],[June],[July],[August],[September],[October],[November],[December])) AS PrimaryUnitPivot
GROUP BY GROUPING SETS ( PrimaryUnit, () );--group by rollup(primaryunit)

That is okay for the misunderstanding.  I sometimes don't explain myself that well.

MikeM670Author Commented:
I added the ('*Unassigned*') to the code to force it to display properly ... ie not after the total field.

SELECT IIF(LEN(RTRIM(primaryUnit)) > 0, PrimaryUnit, '*Unassigned*') AS PrimaryUnit,
           DATENAME(MONTH, ReportedDate) [Month],
           1 AS [CaseID]
