How do I see if records with matching keys are in both files

[fpascal]

How do I see if records with matching keys are in both files and then output only the records that are in the second file into a new file?

proc sql;
create table cohort2 as
  select *
     from etl.inp_claims_lds2013_2014_lejr etl.inp_claims_lds2015_2016_lejr
       where etl.inp_claims_lds2015_2016_lejr.desy_sort_key in (select
        desy_sort_key from etl.inp_claims_lds2013_2014_lejr);
quit;

What do you think is wrong with your code. Seems ok or am i not understanding your description?

my tired eyes didn't capture the missing comma in from clause

from etl.inp_claims_lds2013_2014_lejr   ,    etl.inp_claims_lds2015_2016_lejr

check that. 

also, at late evening here don't trust my eyes

what's your objective

Are you after this logic?

proc sql;
select *
from b
where key in (select key from a);
quit;

[fpascal]

I want to take check each record in file a to see if it is in file b. If so I want to add it to a new file c.

You are better off posting a sample of your data and the requirement

[PGStats]

SAS/SQL doesn't support 3-level variable names. You must use aliasses :

from etl.inp_claims_lds2013_2014_lejr as a, etl.inp_claims_lds2015_2016_lejr as b
       where b.desy_sort_key in (select
        desy_sort_key from etl.inp_claims_lds2013_2014_lejr)

thanks - below it states it cannot find my files but they are in library ETL.  Is there something else i need to add
