Re: Update PostgreSQL from MS SQL trigger

I managed to link PostgreSQL to MSSQL as a linked server but:

select * from [TEST].[test].[public].[users] <<<TEST - name of linked server
in MSSQL , test - Postgres db name, public - schema name, users - table
Returns:
Server: Msg 7312, Level 16, State 1, Line 7
Invalid use of schema and/or catalog for OLE DB provider 'MSDASQL'. A
four-part name was supplied, but the provider does not expose the necessary
interfaces to use a catalog and/or schema.

Works only via OPENQUERY:

SELECT * FROM OPENQUERY (TEST, 'select * from users');

Does anybody know how to query Postgres WITHOUT OPENQUERY.

I found in groups that:

" According to the documentation, SQL-Server supports any Win32 ODBC
driver ... which would include PostgresODBC. However, in practice,
only Microsoft-supplied drivers actually work; ODBC drivers for
Postgres and MySQL mysteriously do not function with SQL-Server (even
though they do work with MS Access).
I think this is incompetence on Microsoft's part rather than malice;
all of this works through DTS, a utility which is responsible for over
300 Knowledge Base issues.
Note: I have not tried any of this with SQL Server 2000, just 7.0 sp3. "

Thank you,

Igor
