Order by but one value is always last - sql

Question

I was wandering if it was possible to Order By a column but have a value always come last.
For instance, I'm doing a COUNT to see how many sales our employees have, differentiated by type of employee.
This is what I'm getting:
+-----------+------------+------------+
| Status | Associate | Internal |
+-----------+------------+------------+
Agended | 5 | 13
Canceled | 0 | 1
Instaled | 10 | 24
TOTAL | 15 | 38
And this is my goal:
+-----------+------------+------------+
| Status | Associate | Internal |
+-----------+------------+------------+
Canceled | 0 | 1
Agended | 5 | 13
Instaled | 10 | 24
TOTAL | 15 | 38
My code is
SELECT CASE WHEN bo.stateofcontract IS NULL THEN ISNULL(bo.stateofcontract,'TOTAL') ELSE bo.stateofcontract END "Status"
, COUNT(CASE WHEN bo.stateofcontract IN ('INSTALED','AGENDED','CANCELED')AND CM3.func = 'ASSOCIATE' THEN 1 END) "Associate"
, COUNT(CASE WHEN bo.stateofcontract IN ('INSTALED','AGENDED','CANCELED')AND CM3.func <> 'ASSOCIATE' THEN 1 END) "Internal"
FROM BO
JOIN CM3 ON CM3.cm = BO.employee
WHERE (bo.stateofcontract IN ('INSTALED','AGENDED','CANCELED'))
GROUP BY ROLLUP (bo.stateofcontract)

Answer 1

You can simplify your query a bit by removing some conditions from the CASE expressions. There is also a little trick in SQL Server using CHARINDEX() which usually works for such ordering:
SELECT COALESCE(bo.stateofcontract, 'TOTAL') as status,
COUNT(CASE WHEN CM3.func = 'ASSOCIATE' THEN 1 END) Associate,
COUNT(CASE WHEN AND CM3.func <> 'ASSOCIATE' THEN 1 END) as Internal
FROM BO JOIN
CM3
ON CM3.cm = BO.employee
WHERE bo.stateofcontract IN ('INSTALED', 'AGENDED', 'CANCELED'))
GROUP BY ROLLUP bo.stateofcontract
ORDER BY CHARINDEX(status, 'Canceled,Agended,Instaled,Total');

Answer 2

You can ORDER BY a CASE expression, or add an ordering column in the SELECT. EG:
SELECT CASE WHEN bo.stateofcontract IS NULL THEN ISNULL(bo.stateofcontract,'TOTAL') ELSE bo.stateofcontract END "Status"
, COUNT(CASE WHEN bo.stateofcontract IN ('INSTALED','AGENDED','CANCELED')AND CM3.func = 'ASSOCIATE' THEN 1 END) "Associate"
, COUNT(CASE WHEN bo.stateofcontract IN ('INSTALED','AGENDED','CANCELED')AND CM3.func <> 'ASSOCIATE' THEN 1 END) "Internal"
FROM BO
JOIN CM3 ON CM3.cm = BO.employee
WHERE (bo.stateofcontract IN ('INSTALED','AGENDED','CANCELED'))
GROUP BY ROLLUP (bo.stateofcontract)
ORDER BY case when Status = 'Canceled' then 1
when Status = 'Agended' then 2
when Status = 'Instaled' then 3
when Status = 'Total' then 4
end
