Using DBLINK in ABAP to retreive data from externam system

Question

Hi All,
Please help me, if anyone knows the answer.
The basis team has created a dblink 'DBL_TEST.YY.XXX.COM'.
Now I have to fetch data from another non-sap external system using this dblink only. Cannot have any entry in DBCON.
I know the procedure of retreiving data using DBCON entry. But since DBCON will not be used here, so I have to use the DBLINK to get data from an external oracle table (say, ZTEST).
I need the procedure to implement the logic in abap program.
Thanks in advance,
Ipsita

My problem is now solved. We created views @the database level, and fetched data using the database view in Native SQL.
In case anybody needs to do, I am giving a short code dump;
    TRY.
        EXEC SQL PERFORMING f_loop_output.
          select alias_type_id,
                 name,
                 molecule_id
          into   :w_tab
          from   ext.V_XXXX
          where molecule_id in
           (Select mh.MOLECULE_ID
            from  ext.V_YYYY mh, ext.V_XXXX al
            where  mh.molecule_id   = al.molecule_id
            and    mh.IS_CURRENT    = 'Y'
            and    al.ALIAS_TYPE_ID = :c_type_id
            and    al.NAME                  = :l_number
          and ALIAS_TYPE_ID in ('AAA','B','CCCC')
        ENDEXEC.
      CATCH cx_sy_native_sql_error INTO l_check_rs.
        l_text  = l_check_rs->get_text( ).
        MESSAGE i005 WITH l_text.
        LEAVE LIST-PROCESSING.
    ENDTRY.
