Question

If I have a table with a status field and I want to know how many records of each status I can do a simple group by. And how about if I want to know the count for 2 records and the count for all the others.

In other words I want this:

Status   Count
-------- -----
Success   X
Running   Y
Failure   Z

but Failure is not Failure on the table, it contains the actual error message, so I want everything that’s different that Success and Running

Answer 1

select case when Status <> 'Success' 
             and Status <> 'Running' 
            then 'Failure' 
            else Status 
        end Status, 
       count (*) [Count]
from atable
group by case when Status <> 'Success' 
               and Status <> 'Running' 
              then 'Failure' 
              else Status 
          end
