Replace full outer join

Hi,

We would like to know the closest alternative to 'FULL OUTER JOIN'. The requirement is that output should contain all the rows.

Following is my SQL

  SELECT   TRIM (ee_company_id),

           fspemp.do_not_termn_by_absence,

           fspemp.employee_termination_date,

           exclude_fax_ind,

           trim(fspemp.first_name),

           trim(fspemp.last_name),

               trim(fspemp.eligibility_comp_id)

    FROM      fmla_employee_eligibility_data eed

           FULL OUTER JOIN

              (SELECT   org.uses_elig_comp_id_ind,

                        opl.org_id,

                        opl.person_id,

                        opl.old_employee_number,

                        opl.eligibility_comp_id,

                        fp.ssn,

                        opl.do_not_termn_by_absence,

                        opl.employee_termination_date
