SQL Server Pivot with grand total? - sql

Question

I am able to pivot dymaically a tale with my parties from a table, the code below works fine and there's not problem below.
SELECT #PartiesNames += QUOTENAME(LTRIM(RTRIM([Party]))) + ','
FROM table1 WHERE [Party] <> ''
GROUP BY [Party]
SET #PartiesNames = LEFT(#PartiesNames, LEN(#PartiesNames) - 1)
SET #SQL =
'
SELECT *
FROM (SELECT
table1.[Party]
,table1.[Accounts]
,[Amount] = FORMAT(SUM(table1.[Amount]),''N0'')
FROM table1
GROUP BY table1.[Party]
,table1.[Accounts]
) AS BaseData
PIVOT(
MAX(BaseData.[Amount])
FOR BaseData.[Party]
IN(' + #PartiesNames + '
)
) AS PivotTable
'
EXEC( #SQL)
And I get a normal pivot table but my question, how can I adjust this code to get a new row or/and column with the total? I've been following this article on how to do it but it's qiute tricky to follow: https://www.codeproject.com/Articles/232181/SQL-Pivot-with-Grand-Total-Column-and-Row
I am open to new solutions on how to solve this problem. I believe one reason why this is tricky to solve is because resources online are not very well explained and it does get tricky very fast, anyway I appreciate the support and suggestions.

If interested in a Helper Function.
This Table-Valued Function returns the Count,Sum,Min,Max,Avg and STDev of virtually any row.
All you have to do is add a CROSS APPLY after your PIVOT.
I should add that you must "EXCLUDE" any numeric column that you DON'T want in the aggregates
Example
Declare #T1 Table ([Branch] varchar(50),[Item] varchar(50),[Sales] int)
Insert Into #T1 Values
('23','Apples',25)
,('23','Coffee',56)
,('23','Bread',22)
,('14','Apples',56)
,('14','Coffee',65)
,('14','Bread',null)
Select Pvt.*
,Ttl.*
From #T1
Pivot ( max(Sales) for Item in ([Apples],[Coffee],[Bread]) ) Pvt
Cross Apply [dbo].[tvf-Stat-Row-Agg]('Branch,OtherColumsToExclude',(Select Pvt.* for XML Raw)) Ttl
Returns
/---- From Pivot ----\ /---- From CROSS APPLY ----\
Branch Apples Coffee Bread RetCnt RetSum RetMin RetMax RetAvg RetStd
14 56 65 NULL 2 121 56 65 60.5 6.3639
23 25 56 22 3 103 22 56 34.33 18.8237
The TVF If Interested
CREATE FUNCTION [dbo].[tvf-Stat-Row-Agg](#Exclude varchar(500),#XML xml)
Returns Table
As
Return (
Select RetCnt = count(value)
,RetSum = Sum(Value)
,RetMin = Min(Value)
,RetMax = Max(Value)
,RetAvg = Avg(Value)
,RetStd = Stdev(Value)
From (
Select Item = xAttr.value('local-name(.)','varchar(100)')
,Value = try_convert(float,xAttr.value('.','varchar(max)'))
From #XML.nodes('//#*') x(xAttr)
) S
Where charindex(','+S.Item+',',','+#Exclude+',')=0
);
