Re: SQL Syntax problem

Hello.

I've got a problem in porting the following select statement from Oracle to
Postgres, because of the characters after "b.bet_id" and "f.ask_id" in the
where clause: (+)
I don't know what these characters mean and how I can transform these into
PostgreSql Syntax.

select ...
from auswahlkatalog k, anspruchkorrektur a, beteiligter b, v_betkorr f
where k.awk_id = a.awk_id and b.bet_id(+) = a.bet_idemp
and a.ask_id = f.ask_id(+);

Hoping for help.
Doris

This kind of conditions are left or right joins, depending on which side
of the equal sign you have the (+).

Something like this

select ...
from
auswahlkatalog k,
INNER JOIN anspruchkorrektur a ON (k.awk_id = a.awk_id),
LEFT JOIN beteiligter b ON (b.bet_id = a.bet_idemp),
RIGHT JOIN v_betkorr f ON (a.ask_id = f.ask_id)

should give you the same results.

This (+) means JOIN
e.g. (+)-marked equations used as a joining condition

To translate it to PGSQL syntax simply remove (+)
:-)
(only one thing i forgot: isn't it OUTER JOIN?...)

Means OUTER JOIN but I don't remember the side.

Not exactly see above

Hi Doris,
In oracle (+) is left outer join or right outer join .
You need to write:
select ...
from auswahlkatalog k, beteiligter b left outer join anspruchkorrektur a
on(b.bet_id = a.bet_idemp) left outer join v_betkorr f on (a.ask_id = f.ask_id)
where k.awk_id = a.awk_id ;

regards,
ivan.
