Re: Synchronizing a table that is in two different databases : Need to dump a table as inserts from db1 and change the insert statements into UPDATE statements

Thank you very much, I on my previous try I did not include the FROM. I
will just do thoroughly checks before COMMIT. Thanks very much.

I think the convention on this list is to bottom-post.

Hi Chris or anyone who can help

When I try this just below, it complains about foo , saying "ERROR: schema
"foo" does not exist." I got stuck on this error for a while now but still
trying to see why but still no luck so far. If you have something please
help

begin;

update foo

set br_desc = bar.br_desc

, br_active = bar.br_active

(rest of columns)

where foo.br_cde = bar.br_cde;

you need to replace "foo" and "bar" with the names of your tables.

I'm stumped. Here's the test that I just ran on both 9.2 and 8.4, and I'm
not getting an error:

drop table if exists foo;

drop table if exists bar;

create table foo (a int, b int);

create table bar (a int, b int);

insert into foo values (1, 1);

insert into foo values (2, 2);

insert into bar values (1, 3);

insert into bar values (4, 4);

update foo

set b = bar.b

from bar

where foo.a = bar.a;

select * from bar;

Perhaps if you want to privately send me the exact statement you are using,
I can take quick look and see if there's something obvious.
