Re: [GENERAL] It is possible to update more than 1 table in the same update statement?
Hi,
Thanks for the reply.
I have write the transaction, but I have some doubt's... If in this example
the Update is executed successfully and the Function it is not, what
happens? The Update automatically rolls back?
Example:
[code]
Begin;
update aae_anuncios
set
n_anunciante = 'teste',
email = 'te...@email.com',
telefone_privado = '123456789',
dat_nasc = '1980-01-01',
n_anuncio = 'teste nome',
telefone_anuncio = '234567890',
id_genero = 'femi',
id_cidade = '1452003',
id_nacionalidade = 'BRAS',
id_orientacao = 'h'
where id_anuncio_externo = '38';
select apr_update_hist_2_1('aae_hist_anuncios',
'id_anuncio_externo',
'38', /* id_anuncio_externo */
'2010-08-31', /* data_inicio */
'2010-12-29', /* data_fim */
'AA' /* Motivo: Aprovação Anúncio */
);
commit;
[/code]
Best Regards,

Yes, transactions (without savepoints) are all or nothing. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Re: [GENERAL] It is possible to update more than 1 table in the same update statement?
Sorry for not explain well. I mean update more than one table at the same time with something like this: update table1, table2 set table1.f1 = 'aaa', table2.date = '2001-01-01' where table1.id = 'x1' and table2.id = 'x1' Something like this is possible? It is the best way to do it?

The only way I can guarantee a transaction is in a Function or there are other ways?
