Try Something like given below:
CREATE OR REPLACE FUNCTION tab_pass(text) returns setof numeric
as
$$
   DECLARE
     rec record;
   BEGIN
      for rec in execute 'select empno from '||$1||' where id = 1'
      LOOP
          return next rec.empno;
      END LOOP;
      return next rec.empno;
   END;
$$ language plpgsql;
