I am attempting to create a random sample using proc sql. I found this article from the SAS website that uses the function RANUNI ( the following paper ) however when I try to run this I get an error saying RANUNI "is not a recognized build-in function name. "
Am I using it incorrectly or is there another function I can use for this?
here is my code using SAS EG to try and get a 10% sample:
proc sql;
connect to sqlsvrasfrprod(datasrc=frproduser=&uidpassword="&pawd" readbuff=3000);
create table sample as
select * from connection to frprod(
select distinct
a.startdate, a.notifydate, a.id, a.ctype, a.type, a.longdesc,
b.account,
c.ctypid
from comp.dbo.comp a
join comp.dbo.accounts b
on a.id=b.id
join comp.dbo.ban c
on left(b.account,6)=c.bannumber and ctypid between 2 and 5
where ranuni(1234) between .45 and .55;
);
quit;
Use a datastep? Extract data from the database, then run a proc surveryselect over that to get your sample:
