The RANK function in SQL is often used to dedup a dataset by specifying the first observation to keep. RANK can also be used to number records within a group. There is no clear substitute for RANK in SAS, i don't want a data step. i want a proc sql.
SELECT a.*, RANK() over (partition by cust_id order by date_created) as n
FROM inputds a
Order by cust_id, date_created
====================================================
i want the sas proc sql equivalent to this.
Thanks

Why?
Look at the monotonic() function which is unsupported, or use SQL pass through.
If you already have an index variable N . You can do this like:
data class;
set sashelp.class;
n+1;
run;
proc sql;
select (select count(*) from class where sex=a.sex and n<=a.n) as rank,a.*
from class as a
order by sex,n;
quit;
