Charles,
What you are saying is important and I want to get out of here on Friday
afternoon also but add your opinion to both.

This sucks performance wise (Charles told you why in the dash dash)
<snip>
-- Pull all rows from the table(s) back to MS SQL server and do the where
locally
select * from LINKEDSVR.MYIBMI.MYLIB.MYTBL where locnbr = '00335';
</snip>

This is MUCH, MUCH, MUCH better on performance.
<snip>
-- Sends the statement to linked server for processing
select * from openquery(LINKEDSVR, 'select * from MYTBL where locnbr =
''00335''');
</snip>

I assume you're trying to set up a linked server?

https://www-01.ibm.com/support/docview.wss?uid=nas8N1014514

Once you get connected, note the following:

-- Pull all rows from the table(s) back to MS SQL server and do the where
locally
select * from LINKEDSVR.MYIBMI.MYLIB.MYTBL where locnbr = '00335';

-- Sends the statement to linked server for processing
select * from openquery(LINKEDSVR, 'select * from MYTBL where locnbr =
''00335''');

--OPENQUERY() isn't just for SELECTS
delete from openquery(LINKEDSVR, 'select * from MYTBL where locnbr =
''00335''');

Hi,

Can you please point me in the right direction? We need to connect our

SQL

server to the A/S400? I've installed IBM Access for Windows 7.1, and

I'm

not able to connect from SQL Studio 2014 to the A/S400.

Thank you,
