Обсуждение: Selecting data from a table created in another database...
I don't know if this can be done... In MSSQL Server I can access a table created in another database (on the same server, of course) by using the following syntaxis... select * from databasename..tablename where condition; Can I do this in postgres? I'm using version 7.2 on a redhat server... Thank you for your help... Ligia

Sorry, you can't do cross-db queries with PostgreSQL. Take a look at /contrib/dblink as an option. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026
Hi Ligia, When I need to do this I use a scripting language like PHP, Perl or ColdFusion to select from one db and insert into another. As a matter of fact I had to do this exercise just yesturday. I like it as I find I have much more freedom to gather data, organise it then insert it. It's easy to view the output of your selects on the screen and when happy do the insert(s). Hope this helps.

hi Ligia, there was a posting to this list some time ago, about the same question. I just found it as I had the same question as you: http://archives.postgresql.org/pgsql-sql/1998-05/msg00091.php (in short: it is not possible in Postgres) the mail is from 1998, but I just tried to make a select using mydatabase.mytable as table name in a select statement and this does not work.
