SQL Server OpenQuery to DB2 file member

I'm trying to use SQL Server OpenQuery to read data directly from a DB2 file member (code below). I don't want to do anything special on the IBM side to make this possible, like creating aliases. I just want to be able to change the file member in my OpenQuery statement and get the data I need.

Code below results in this error:
[IBM][iSeries Access ODBC Driver][DB2 UDB]SQL0104 - Token ( was not valid.

I've tried surrounding different parts with single quotes, double quotes, slashes, etc. Thanks in advance.
SELECT * FROM OPENQUERY(linkedserver, 'SELECT * FROM Library.File(member)')

Open in new window

If I understand correctly, you need to dynamically specify the query you are executing.  The openquery construction does not allow parameters.  And maybe the member should be separated by dot rather brackets.  YOu would need to use something like this:
--assuming you receive one column name id of type int
declare @n nvarchar(2000),@member nvarchar(200)
set @member='member'
set @n='SELECT id FROM OPENQUERY(linkedserver, ''SELECT * FROM Library.File.'+@member+''')'
create table #t(id int)
insert into #t(id)
exec(@n)

In the simplest case (b/c I don't need to change the member as frequently as you're perceiving), using your select statement causes confusion in the 4-part name. Library.File.member is interpreted as owner.database.table, which isn't the case.
So
SELECT id FROM OPENQUERY(linkedserver, 'SELECT * FROM Library.File.member')
doesn't work, either.
Including the 4-part name results in an error, as well:
SELECT * FROM OPENQUERY(linkedserver, 'SELECT * FROM Server.Library.File.member')
returns
[IBM][iSeries Access ODBC Driver][DB2 UDB]SQL0104 - Token . was not valid.

It appears anything after the file doesn't get parsed or interpreted correctly.

What abount this:

SELECT id FROM OPENQUERY(linkedserver, 'SELECT * FROM File')

The library should be the default library for the user used by the link server.

Right, but it's not the file I'm concerned about, I can get to that consistently, it's which file member gets returned. That's what isn't consistent. Like this:
File = Sales
Mem1 = 2008
Mem2 = 2009
Mem3 = 2010
and so on.

I want to be able to query the Sales(2009) file member from SQL Server, specifically.
