In the ODBC DSN you can specify the database.

In PostgreSQL:
CREATE TABLE test_tbl (test_id NUMERIC(10) NOT NULL PRIMARY KEY,
test_name VARCHAR(32));

In PostgreSQL:
INSERT INTO test_tbl VALUES (1, 'From PostgreSQL');

In Oracle over HSODBC:
INSERT INTO "test_tbl"@dblinkname VALUES (2, 'From Oracle');

TIP 2: Don't 'kill -9' the postmaster




Hi Jonah;

The above works so long as the test_tbl lives in the 'postgres' database
(the default db). If I run the folowing it does not work. Oracle cannot
find the table because it's not connecting to the testdb database. The
postgres logs indicate a connection attempt via the postgres database.

The correct database is specified in the odbs DSN as well, but seems to
have no effect.

Thanks for your help...


In PostgreSQL:
CREATE database testdb;

\c testdb

CREATE TABLE test_tbl (test_id NUMERIC(10) NOT NULL PRIMARY KEY,
test_name VARCHAR(32));

In PostgreSQL:
INSERT INTO testdb.test_tbl VALUES (1, 'From PostgreSQL');

In Oracle over HSODBC:
INSERT INTO "testdb.test_tbl"@dblinkname VALUES (2, 'From Oracle');

Hi Joshua;


I do have the database name in the ODBC DSN but it seems to have no
effect.  In the below samples, sample 1 works and sample 2 does not.

Thanks for your help


Sample 1:
In PostgreSQL:
CREATE TABLE test_tbl (test_id NUMERIC(10) NOT NULL PRIMARY KEY,
test_name VARCHAR(32));

In PostgreSQL:
INSERT INTO test_tbl VALUES (1, 'From PostgreSQL');

In Oracle over HSODBC:
INSERT INTO "test_tbl"@dblinkname VALUES (2, 'From Oracle');

Sample 2:
In PostgreSQL:
CREATE database testdb;

\c testdb

CREATE TABLE test_tbl (test_id NUMERIC(10) NOT NULL PRIMARY KEY,
test_name VARCHAR(32));

In PostgreSQL:
INSERT INTO testdb.test_tbl VALUES (1, 'From PostgreSQL');

In Oracle over HSODBC:
INSERT INTO "testdb.test_tbl"@dblinkname VALUES (2, 'From Oracle');

Hmm... I've gotten it to work before with differing database names.  I
don't recall doing anything special to configure it.
