Comples SQL

Question

Hi All ,
I have below part in WHERE clause of my query :
CCD.PERSONAL_ID(+) = per.PERSONAL_ID AND (CCD.personal_id,CCD.card_seq) in (select personal_id, max(card_seq) from
CREDIT_CARD_DATA group by personal_id)
I have added outer join (+) in first part of the above query and need to add this in second part also, can any body tell me how we can do this.
I just want to fetch all the records even second table does or does not have. It may be possible second table does have more than one record or may not have any records.
I hope I am clear in above statement.
Thanks in advance.

Just guessing, but perhaps this is a case for ANSI syntax to overcome the limitations of oracles outer join syntax...
SQL> WITH per as (select 1 as personal_id from dual union all
  2               select 2 as personal_id from dual union all
  3               select 3 as personal_id from dual)
  4      ,ccd as (select 1 as personal_id, 123 as card_seq from dual union all
  5               select 1, 125 from dual union all
  6               select 2, 234 from dual)
  7  -- END OF TEST DATA
  8  select per.personal_id, ccd.personal_id, ccd.card_seq
  9  FROM per LEFT OUTER JOIN (select personal_id, max(card_seq) as card_seq from ccd group by personal_id) x ON (x.personal_id = per.personal_id)
10           LEFT OUTER JOIN ccd ON (ccd.personal_id = x.personal_id AND ccd.card_seq = x.card_seq)
11  /
PERSONAL_ID PERSONAL_ID   CARD_SEQ
          1           1        125
          2           2        234
          3Or something like...
SQL> WITH per as (select 1 as personal_id from dual union all
  2               select 2 as personal_id from dual union all
  3               select 3 as personal_id from dual)
  4      ,ccd as (select 1 as personal_id, 123 as card_seq from dual union all
  5               select 1, 125 from dual union all
  6               select 2, 234 from dual)
  7  -- END OF TEST DATA
  8  select per.personal_id, ccd.personal_id, ccd.card_seq
  9  FROM per LEFT OUTER JOIN ccd ON ((ccd.personal_id,ccd.card_seq) IN (select personal_id, max(card_seq) as card_seq from ccd group by personal_id) AND ccd.personal_id = per.personal_id)
10  /
PERSONAL_ID PERSONAL_ID   CARD_SEQ
          1           1        125
          2           2        234
          3
