Обсуждение: faking writable views as tables
Hi folks, I'm using several writable views (-> update & insert rules) and got trouble with pgadmin - it refuses to insert/edit values since it sees the table as a view and believes views are never writable. So i've just set the reltype in pg_class to 'r'. The frontends now see it as a writeble table again, but when dropping the table, i've got a warning, that some file (seems to be <oid-of-schema>/<oid-of-table>) could not be deleted. Is this the table storage file, which simply doesn't exist on views ? Are my changes to pg_class dangerous in any way ? cu -- --------------------------------------------------------------------- Enrico Weigelt == metux IT service phone: +49 36207 519931 www: http://www.metux.de/ fax: +49 36207 519932 email: contact@metux.de --------------------------------------------------------------------- Realtime Forex/Stock Exchange trading powered by postgresSQL :)) http://www.fxignal.net/ ---------------------------------------------------------------------

That would be a pgadmin bug. Please report it to them. > So i've just set the reltype in pg_class to 'r'.

Yes. The current way to do writeable VIEWs is through the RULE system, not with TRIGGERs :) Cheers, D -- David Fetter david@fetter.org http://fetter.org/ phone: +1 510 893 6100 mobile: +1 415 235 3778 Remember to vote!
