Hi,
i'm trying to make update on multiple tables but don't know how.
is something like this posible with postgresql?
update table1
join table2 on (table1.id=table2.t1)
join table3 on (table2.id=table3.t2)
set table1.name='test', table2.sum=table1.x+table2.y,
table3.cell='123456789'
where table1.id=6
I don't know of an SQL variant to handle this case. Usually people are
trying to update a single table based on joining to several others.
In your case you'll have to issue three update statements wrapped in a
transaction.
