Hi all,
I would like to keep the first two observations ordered by date by group using sql in one step
proc sql;
select *, ROW_NUMBER()
from test_sql
where ROW_NUMBER<=2
order by cusip date;
quit;
The above does not work
Many thanks in advance
Regards
George
ROW_NUMBER() isn't valid in SAS SQL, I think that's MS SQL?
All DBs do this one a bit differently, Oracle is ROWNUM for example.
Have you tried using the MONOTONIC() function or using the OBS= data set option?
Note that you were also missing a comma in the ORDER BY clause.
proc sql;
create table want(obs=2) as
select *
from test_sql
order by cusip, date;
quit;
proc sql;
select * , monotonic() as rowNum
from test_sql
where calculated rowNum <=2
order by cusip, date;
quit;

Note that SQL does not guarantee that rows will be processed in the table order.
If you read a single table and use option proc sql nothreads, it should still happen though.
