You need a Units table or at least a Units set to look for all units. after that the rest is easy, just add a RIGHT JOIN.
SELECTcount(fr.[Unit]) as Actual,
fr.unit,
[1st_of_month],
last_of_month
FROM [lchs_live].[dbo].[Full_Referrals_Dataset_live] fr
RIGHT JOIN Units u ON fr.unit = u.unit
where RfR1 = '18 month project'
group by fr.unit,
[1st_of_month],
[last_of_month]
Uh, Luis. Isn't that RIGHT JOIN going to leave you with NULLs in the resulting [1st_of_month], last_of_month columns? And also I think you'd want to refer to u.unit and not fr.unit.
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
