Hi Dan,

My comment was all with respect to CallableStatement (procedures or 
functions). Am I still wrong?

Even if you can create large BLOBs/CLOBs, you can't use them with a 
CallableStatement, right?
Even if they could be, I am not sure what would have to be done. I have 
used existing code in the network client, and I do not know the stream 
implementations well enough to know how they handle large data volumes.

If someone has more knowledge about these issues, I would appreciate if 
a Jira issue was created to track further work required to make the 
CallableStatement.getCharacterStream implementation better.
