Random Sample with Proc SQL

eaherbst — Wed, 06 Mar 2019 15:43:50 GMT

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:
