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
notfunction with SQL-Server (even though they do work with MS Access).I think this is incompetence on Microsoft's part
ratherthan 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
