RE: AS/400 DSN on SQL Server

FWIW, we tried linked servers but abandoned them. Like you said, performance is bad. Also our T-SQL guys refused to learn DB2 syntax.

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>
