[GENERAL] Accessing a database form another database
I've got some GIS tables that I want to use across several projects and currently I've got each project in a separate database. So say I've got two databases, one for the Spacely Sprookets project and one for the Cogswell Cogs contract, but I want to access my WorldMap tables in my GIS database to make maps for both of these projects. How do I reference a table that's in another database? Or should I organize my PostgreSQL data differently?

Create a schema each for Spacely and Cogswell, then one for WorldMap. http://www.postgresql.org/docs/current/static/sql-createschema.html Cheers, David. -- David Fetter da...@fetter.org http://fetter.org/ Phone: +1 415 235 3778 AIM: dfetter666 Yahoo!: dfetter Skype: davidfetter XMPP: david.fet...@gmail.com Remember to vote!

You can use dblink for this purpose: http://www.postgresonline.com/journal/index.php?/archives/44-Using-DbLink-to-access-other-PostgreSQL-Databases-and-Servers.html -- Guy Rouillier -- 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] Accessing a database form another database
Just a thought, but would it not be possible to add a trigger written in python that makes a connection to another database and does what it needs to? I have not done this, but if it is possible it should solve your problem and one that I have. It should allow updates and selects. I am sure the docs will tell you how to do perl or python based triggers and if you can use external modules in them...if you can, it would be a rather straight forward python app that accesses the GIS tables using a DB connector (postgres or mysql or what ever). Since I have not read much (more or less nothing) about triggers I could be way off base and entirely wrong.
