proc sql nowarn;
  create table table3 as
    select a.stdate, a.enddate, a.comm_cou
      from table1 as a
        right join table3 as b
          on a.stdate=b.enddate and
            a.comm_cou=b.comm_cou
  ;
quit;

WARNING: This CREATE TABLE statement recursively references the target table. A consequence of this
is a possible data integrity   problem.
