format max date

tmm — Tue, 12 Jun 2012 21:15:12 GMT

I am trying to format a max query for the date. My code is:

proc sql;

create table lib.market as

(select distinct

id,

max(eff_dt) as eff_dt

from lib.cleaning

group by id);

run;

The table has in it:

id eff_dt

111 1/1/1990

111 1/1/1991

111 1/12/1991

111 1/15/2010

222 1/1/1991

222 1/1/1993

222 1/1/2011

It returns the following:

id eff_dt

111 -21914

222 13419

How do I make it appear with the dates. I am sure it is some format but not sure.

hi ... fyi ...

1/ you can get rid of the parentheses

2/ SQL ends with a QUIT

3/ you are grouping by ID so you can get rid of DISTINCT

proc sql;

create table want as

select id, max(eff_dt) as eff_dt format=mmddyy10.

from have

group by id;

quit;
