Hi,
I've got PsotgreSQL 7.3.
My problem is joins. I've seen the syntax on joins and have sucessefully
used SQLs with joins, but I've got some other big SQL statements using many
and complexjoins.
Simplified example:select G.SELID, G.TEXT, L.ID as SELLEVELID , L.SELLEVEL, L.LEVELJOIN, L.LEVELTEXT, C.ID as
KRITERIENFELDID,C.SELFLD from G, L, C where and G.SELID = L.SELID (+) and L.SELID = C.SELID (+) and
L.SELLEVEL= C.SELLEVEL (+)
How can i write this in Postgres? As the problem is that I use one sametable for varios joins. This is a problem in
Postgres.Any ideas?When I use the same table in say 3 or 4 joins in one SQL, is the onlysolution unions?? Adn if so,
theperformance will certainly suffer?
thanks!
Carla
