Again, yes, your help would be very much appreciated! Check out the
code, get on derby-dev, ask questions, we'll be glad to help.

Perhaps it could help : the DBMS Mckoi ( http://mckoi.com/database/ )
has got a JDBC driver that supports blob streaming over network. Code is
open.
I tried with IBM DB2, and same as Derby, streaming isn't supported with
their JDBC driver. For a so big DBMS, I found it odd.
I'm aiming to try Oracle, but I have some difficulties to use it. Does
anyone knows if the Oracle JDBC supports blob streaming ?
It would be difficult to implement in Derby ? I'm familiar with java
network developpment. I develop in java for 4 years.

Right... Network server currently sends whole datatype over to client.
While this works for most datatypes, since they are limited in size,
it may be a problem for clob/blob types. Server needs to be able to
stream these large datatypes over the wire on demand, so no matter
whether we have a common client or not, server needs to be enhanced.

Thanks for the offer.. It would really be great to have more developpers
working on Derby. Join the derby-dev alias to participate in the

Derby embedded driver already has the capability to stream blob/clob,
without requiring reading them completely into memory. It would be great to
enhance Derby network server and Derby client to support this kind of
behavior.

This may be a dumb question...
Maybe its hindsight, but why isn't the Server Framework either a subclass or
an extension to the embedded driver? Someone had posted that the Network
Driver utilized the embedded driver... (Or is that bathtub gin affecting my
memory?)
I guess it goes more to the point of why not have more focus on a "universal"
driver?

Really the two drivers are doing different things, one has to convert
requests into messages using DRDA over tcp/ip, the other just calls java
methods.
