How to get specific year members

AliMN — Wed, 06 Feb 2013 16:20:40 GMT

Hi All,

I have a large data and I would like to split into two parts, one will be for the people who were active in 12 months and another will be the people who were not active. So if the member has 12 months = active if not member is inactive. I would like to add another column indicating active, inactive Here's an example of my data. Any help is appreciated.

ID#	MONTH
12	January 1, 2011
12	February 1, 2011
12	March 1, 2011
12	April 1, 2011
12	May 1, 2011
12	June 1, 2011
12	July 1, 2011
12	August 1, 2011
12	September 1, 2011
12	October 1, 2011
12	November 1, 2011
12	December 1, 2011
13	January 1, 2011
13	February 1, 2011
13	March 1, 2011
13	April 1, 2011
14	March 1, 2011
14	April 1, 2011
14	May 1, 2011
14	June 1, 2011

Does your data only have the 12 months you care about in it? are there unique entries?

If not you can just count how many times a member is present.

proc sql;

create table want as

select id, month, case when count(id) =12 then 'Active' else 'Inactive' end as status

from have

group by id;

quit;
