Perhaps you could use, what I think is called,
 an "in-line" view, like
proc sql;
  create table data2 as
        select *, monotonic() as row
          from ( select distinct * from data order by 1 )
   ;
quit;
Because the "distinct" keyword is in the view, you don't need to
use "order by" on the output

Hi Folks,

Thanks for the help. I was hoping monotonic() could be used to index the
final sorted output as in the following.

data data;
   input alpha $ @@;
cards;
w f h a v a d v d a d
d s a f g h g f h d t
f d h t r h y t s f g
t r e w t r y t e t y
e t y t e r l q w y o
;run;

proc sql;
   create table data as
   select distinct *
   from data
   order by 1;

   create table data as
   select *, monotonic() as row
   from data;
quit;

Unless one of those mysterious parameters Kevin mentions produces the final
table as above using a compact syntax such as:

select distinct *, monotonic(parameter= ) as row
from data
order by 1;

I'll stick with a DATA step after exiting PROC SQL.

Once again thanks for the help.

Dave.


P.S. I know I can get the same result using NODUP in PROC SORT followed by
a DATA step but I didn't want to exit SQL and go straight back into it.
