Обсуждение: Select from different database

Hi All

Is it possible to fetch data from another database than the current?
E.g. like in Oracle I can select data from 2 different DB's like this:

select * from db1.table1 as tbl1, db2.table2 as tbl2 where tbl1.id1 =
tbl2.id2;

Jacob

Is it something that will come in later versions?

Jacob

New FAQ item:

    <H4><A href="#4.25">4.25</A>) How do I perform queries
    using multiple databases?<H4>

    <P>There is no way to query any database except the current one.
    Because PostgreSQL loads database-specific system catalogs, it is
    uncertain how a cross-database query should even behave.</P>

    <P>Of course, a client can make simultaneous connections to
    different databases and merge the information that way.</P>
