AS/400 DB2 linked server problem

I'm using MS-SQL management studio and added linked server on my environment.
I can use openquery for my linked server.

ex)
select * from openquery(linked_server, 'SELECT * FROM [LIB_NAME].[PF_NAME]')

It works fine.
But, I wanna know if I can change the above expression like this.

select * from [linked_server].[LIB_NAME].[PF_NAME]

Of course, I failed.. Please let me know how this can work.
Thanks.

sql server uses 4 part names, so you just need to try some combinations for your query
try

select * from [linked_server]..[LIB_NAME].[PF_NAME]
select * from [linked_server].[LIB_NAME]..[PF_NAME]

I tried your query but I also failed.
please give me the descript of the 4 parts.

[linked_server].[what?].[LIB_NAME].[PF_NAME]
[linked_server].[LIB_NAME].[what?].[PF_NAME]

I also tried but failed.

I'm sure that my server's machine name is correct and I also tried my ip address of the server.
But failed...
Do you have any other clue for this?

momi_sabag

what is the exact error message you get?

ASKER

the error message is below.

An invalid schema or catalog was specified for the provider "MSDASQL" for linked server "DNA".

is it possible that this is a permission issue?
can you trace the As400 DB2 and check if your request ever made it through

I didn't solve this problem yet but I'll accept the answer.
If the description for the connection 4 parts is correct, there might be a clue.
Anyway thanks.
