Calculating Horizontal Totals in Pivot in MS SQL Server 2008

Question

I want to know how to calculate Row subtotals.

My table looks like this:

FCode   DMAR15  DMAR02  DMAR13  DMAR06
F83006     292     334     111     152
F83025     272     298      80     140
F83048     166     179      56      57
F83049      27      32      15      17
F83050     105     112      45      53
F83635     139     153      41      41

My script is:

SELECT [FCode],
       [DMAR15],
       [DMAR02],
       [DMAR13],
       [DMAR06],
       [PCVDR41],
       [PCVDR42],
       [CLDP031],
       [CLDP003],
       [CLDP012],
       [CLDP028],
       [CLDP023],
       [CLDP021],
       [CLDP016],
       [CLDP022]
FROM   (SELECT [FCode],
               [Aggregate],
               [QName]
        FROM   [dbo].[tblMiquestResults]
        WHERE  AuditDate = '2012-09-30') AS SourceTable 
PIVOT (AVG (Aggregate) FOR [QName] IN ([DMAR15], [DMAR02], [DMAR13], 
                                       [DMAR06], [PCVDR41], [PCVDR42], 
                                       [CLDP031], [CLDP003], [CLDP012], 
                                       [CLDP028], [CLDP023], [CLDP021], 
                                       [CLDP016], [CLDP022])) AS P 

I want to make it look like this:

FCode   DMAR15  DMAR02  DMAR13  DMAR06
F83006     292     334     111     152
F83025     272     298      80     140
F83048     166     179      56      57
F83049      27      32      15      17
F83050     105     112      45      53
F83635     139     153      41      41
Total     1001    1108     348     460

Answer 1

One way of doing it

SELECT CASE WHEN GROUPING([FCode]) = 1 THEN 'Total' ELSE [FCode] END AS [FCode],
       SUM([DMAR15]) AS DMAR15,
       SUM([DMAR02]) AS [DMAR02]
        /*TODO: Rest of columns*/
FROM   (SELECT [FCode],
               [Aggregate],
               [QName]
        FROM   [tblMiquestResults]) AS SourceTable 
PIVOT (AVG (Aggregate) FOR [QName] IN ([DMAR15], [DMAR02], [DMAR13], 
                                       [DMAR06], [PCVDR41], [PCVDR42], 
                                       [CLDP031], [CLDP003], [CLDP012], 
                                       [CLDP028], [CLDP023], [CLDP021], 
                                       [CLDP016], [CLDP022])) AS P 
GROUP BY GROUPING SETS ((FCode),())

Answer 2

Well given your above table (not looking at your query) following is a query to do the rowsum.

SQLFIDDLE DEMO

select a.fcode, a.DMAR15,  a.DMAR02,  
a.DMAR13,  a.DMAR06, (a.DMAR15 +  a.DMAR02 +
a.DMAR13 +  a.DMAR06) as RowSum
from demo a
;

|  FCODE | DMAR15 | DMAR02 | DMAR13 | DMAR06 | ROWSUM |
-------------------------------------------------------
| F83006 |    292 |    334 |    111 |    152 |    889 |
| F83025 |    272 |    298 |     80 |    140 |    790 |
| F83048 |    166 |    179 |     56 |     57 |    458 |
| F83049 |     27 |     32 |     15 |     17 |     91 |
| F83050 |    105 |    112 |     45 |     53 |    315 |
| F83635 |    139 |    153 |     41 |     41 |    374 |
