Question

I’m trying to return a given number of server names and then a count of how many came back. For instance:

select servername, count(distinct servername) number
from TABLE
where [target] = 'blah'
group by servername

This returns the following:

servername      number
server1         1
server2         1

What I’m attempting to get is for the “number” column to read “2,” because there are 2 distinct servernames. This should be incredibly simple, but I’m completely at a loss.

Answer 1

You can use a correlated subquery:

select distinct servername, 
  (select count(distinct servername) 
   from yourtable
   where target = 'blah') number
from yourtable
where target = 'blah'
