Nina,

There are several ways here are two:

proc sql; create table b as select * from a where monotonic() < 10 order by x ; quit;

and

proc sql ; select * from a (obs = 9) order by x ; quit ;

Toby Dunn

are there better ways of doing this?

the goal is to "look and analyze" at the data coming from a hundred million row table first before running a full throttle query

* this is here just to generate some sample data in real life this would not exist as the sql connection would provide the data; data a;do x=1000 to 500 by -1;output;end;

proc sql; create table b as select *, monotonic() as _m_ from a where calculated _m_ < 10 order by x ; quit; data _null_;set b;put(_all_)(=);run;
