Can I use ROWNUM Pseudo column in proc sql? like other database statement?
eg. PROC SQL;
SELECT * FROM employees WHERE ROWNUM < 11;
QUIT;
No, rownum is a database specific item, not part of ANSI SQL. You can code it simply in datastep.
Much easier done in a data step:
data want;
set have (obs=10);
run;
SQL either takes much more coding:
proc sql;
create table want (drop=count) as
select *, monotonic() as count
from sashelp.class
having count < 11;
quit;
or will create a WARNING:
proc sql outobs=10;
create table want as select * from sashelp.class;
quit;
Edit:
to simply create a row number, use this data step:
data want;
set have;
rownum = _n_;
run;
