ANSI/ISO JOIN SYNTAX

Question

DEAR Friends,
How can i write the ansi/iso syntax for below query
select a.company,b.fpm_ac_code from facmast a,fparty b, fstatus c
where a.company = b.company(+)
and a.fac_ac_code = b.fpm_ac_code(+)
and a.company = c.company(+)
one method is
select a.company ,b.fpm_ac_ccode from facmast a right outer join fparty b on a.company = b.company
and a.fac_ac_code = b.fpm_ac_code
,facmast c right outer join fstatus d on c.company = d.company
but this is equivalent
select a.company,b.fpm_ac_code from facmast a,fparty b,facmast c, fstatus d
where a.company = b.company(+)
and a.fac_ac_code = b.fpm_ac_code(+)
and c.company = d.company(+)
pls help me

I would transpose this statement...
select a.company, b.fpm_ac_code
from facmast a, fparty b, fstatus c
where a.company = b.company(+)
and a.fac_ac_code = b.fpm_ac_code(+)
and a.company = c.company(+)
into this...
SELECT a.company, b.fpm_ac_code
FROM facmast a
LEFT OUTER JOIN fparty b
ON a.company = b.company
AND a.fac_ac_code = b.fpm_ac_code
LEFT OUTER JOIN fstatus c
ON a.company = c.company
I think this may be closer to what you want.
Remember, the (+) goes on the side that is deficient in information; but the LEFT or RIGHT keyword points to the table on the side of the JOIN clause (not the ON condition) from which you want information.
Best!
