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 complex
joins.
Simplified example:
select G.SELID, G.TEXT,
L.ID as SELLEVELID , L.SELLEVEL, L.LEVEL

Updating some rows in tab1 with corresponding values from tab2, pgsql style:
UPDATE tab1
SET value=T2.VALUE
FROM tab2 T2
WHERE T2.restr=1
AND tab1.key=T2.key<<
The same for MSSQL:
UPDATE tab1
SET value=T2.VALUE
FROM tab1 T1
JOIN tab2 T2

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 complex
joins.
Simplified example:
select G.SELID, G.TEXT,
L.ID as SELLEVELID ,
Sorry if I was not that clear...but in fact the (+) is the join operator in
Oracle.
The statement in question is about making 3 left outer joins on 3 diferent
tables.
G, L and C are in fact 3 diferent tables.
