RE: User Space or Data Queue or PF or IFS

It is a true ODBC driver for the iSeries in native API's.
If the user requests the records, I have to be able to 
retrieve them. 
I think I will use the IFS for anything over 16MB and
just live with the performance hit.

I've been reading some of the replies, but I'm still confused about 
one thing. It might be worthwhile to step back and consider: What is 
the purpose to these machinations? That is, why not just retrieve 
one record at a time from the SQL server instead of a big bunch of 
records?

Cheers! Hans
