Proc report - COUNT DISTINCT

[elsfy]

Hi,

I would like to know the equivalent of proc sql count distinct operation.

I want to count the number of contrats and the number of people in a dataset but for my purpose i want to do it in a proc report (if possible).

So i have id_contrat and id_person that are non numeric variables and i only managed to calculate the number of contrats corresponding to the number of observations. I don't want to display each id_contrat nor id_person. 

I did this so far :

proc report data = a ; 

columns ('Perimeter' var_to_group_by n) ;

define var_to_group_by / group ; 
define n / 'nb_contracts' ;
run ; 

Thanks

proc report data=have ;
   column group members ;
   define group/group ;
   define members/analysis n ;
