format max date

[tmm]

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;

Ok, how do I format it so it looks like 01jan1990
