Create a grand total row in sql server - sql-server

Question

I'm writing a query where in there should be a total row at the end of the table that gives the sum of the closed , open, reassigned columns.
I'm able to make a pivot, but unable to know how to place a row in the end. I've searched online but mostly found solutions for creating a column and a row or just column. I'm into Dev, dunno much about the databases. below is my pivot. please let me know how can i do this.
select *
from
(
select [case owner] as AGENT, [final status]
from StatusTable
) src
pivot
(
count([final status])
for [final status] in ([CLOSED], [OPEN], [REASSIGNED])
) piv
The current output is as below image
And here I want an extra row as shown below.
TOTAL | 2 | 8 | 2

Answer 1

You can use UNION ALL to concat rowsets with identical columns:
with ctePivot as (
select *
from
(
select [case owner] as AGENT, [final status]
from StatusTable
) src
pivot
(
count([final status])
for [final status] in ([CLOSED], [OPEN], [REASSIGNED])
) piv
)
select * from ctePivot
union all
select 'TOTAL', sum([CLOSED]), sum([OPEN]), sum([REASSIGNED]) from ctePivot
Or the simpler variant with only a GROUP BY ROLLUP:
select ISNULL([case owner], 'TOTAL') as AGENT,
SUM(CASE WHEN [final status]='CLOSED' THEN 1 ELSE 0 END) [CLOSED],
SUM(CASE WHEN [final status]='OPEN' THEN 1 ELSE 0 END) [OPEN],
SUM(CASE WHEN [final status]='REASSIGNED' THEN 1 ELSE 0 END) [REASSIGNED]
from StatusTable
GROUP BY ROLLUP ([case owner]);

Answer 2

Assuming agent is a key field, you can aggregate on that and use GROUP BY ROLLUP():
select coalesce(piv.agent,'Grand Total') agent
,sum(piv.closed) closed
,sum(piv.open) open
,sum(piv.reassigned) reassigned
from
(
select [case owner] as AGENT, [final status]
from StatusTable
) src
pivot
(
count([final status])
for [final status] in ([CLOSED], [OPEN], [REASSIGNED])
) piv
group by rollup(piv.agent)

Answer 3

If you write your query as a group by instead of a pivot, you can use with rollup to get your total row. E.g.:
select
[AGENT] = case when grouping([case owner])=1 then 'TOTAL' else [case owner] end,
[CLOSED] = sum(case when [final status] = 'CLOSED' then 1 else 0 end),
[OPEN] = sum(case when [final status] = 'OPEN' then 1 else 0 end),
[REASSIGNED] = sum(case when [final status] = 'REASSIGNED' then 1 else 0 end)
from StatusTable
group by [case owner]
with rollup
