Oleg,
I've just spent the last couple of hours trying to get this to work - with
little success.
I managed to create the linked server using both Enterprise manager and also
Query Analyser using
EXEC sp_dropserver 'Postgresql'
EXEC sp_addlinkedserver 'Postgresql', 'Postgresql', 'MSDASQL',
'DATABASE=[dbname];SERVER=localhost;PORT=5432;A0=0;A1=6.4;A2=0;A3=0;A4=0;A5=
0;A6=;A7=100;A8=4096;A9=0;B0=254;B1=8190;B2=0;B3=0;B4=1;B5=1;B6=0;B7=1;B8=0;
B9=0;C0=0;C1=0;C2=dd_'
I generated the DSN above from a linked Access table (I've replaced my
actual database name with [dbname] and it works when I test the connection
string in Access.
I tested the connection with:
select * from postgresql...test
select * from postgresql..test
select * from postgresql.test
(The documentation suggests that it wants a fully qualified table name so I
tried all of the above in case there was some mapping taking place in any of
the drivers).
This reports that the linked server has been created but I cannot run SQL
Server queries against it, and cannot find where I can get more details
relating to the OLE DB errors produced.
If anyone can get any further with pls post as I think it would open up some
interesting possibilities.
sb
