Re: Comparing two tables of different database

Nicholas,

To use the dblink:

1. In your postgres server you should find a file *dblink.sql*.
In my beta installation is in *share/postgresql/contrib*. It is the
installation for the dblink contrib module that usually is already compiled
in. It will create a lot of dblink functions.

2. on database2 create a function nammed db_datbase1() which returns
"dbname=database1" (if you need a login use "dbname=database1 password=xxx",
you can also specify host= port= to connect in a remote postgresql database)

3. now execute the sql:
select * from dblink(db_database1(), 'select "id", "name", "time" from
pr_1') as pr_1("id" integer, "name" text, "time" time)
then you will see the table "pr_1" on the datbase2
