Grouping lowest to highest when blank value exists

[Q1983]

proc sql;

create table setup_summ as

select cost_ctr,count(cnt) as cnt1

from setup

group by cost_ctr

order by cost_ctr

;quit;

Cost_ctr   Cnt

                   10

4320102    133

4320105    294

4320545    957

4327979    619

4327983    489

4327984    493

4327985    529

4327996    51

I tried defining cost_ctr as both numeric and text. As you can see if no cost_ctr exists the blank cost center goes to the top

I want the blank cost center to show at the bottom however I still want to sort by cost center from lowest to the highest. The sequence should be the same except the blank one should show at the bottom.  How can I accomplish this

Try this:

proc sql;

   title 'A UNION B';

 create table setup_summ as

select cost_ctr,count(cnt) as cnt1

from setup

where your_variable ne ' ' /*Please notice here and change accordingly*/

group by cost_ctr

order by cost_ctr

   union

  select cost_ctr,count(cnt) as cnt1

from setup

where your_variable=' ' /*Please notice here and change accordingly*/

group by cost_ctr;quit;

In sql you can do something like this. 

proc sql;
select a.cost_ctr, a.cnt from 
(select cost_ctr, cnt from have)a
cross join
(select  max(cost_ctr) +1 as nmax from have)b
order by coalesce(a.cost_ctr, nmax) ;
quit;
