Thank you. I think that 'dual' will solve few my problems. I'm not an 
oracle developer so I didn't know about this method. Really strange for 
me - it was so easy in Sybase or Postgres to get values from functions 
(not only scalars).

I don't want to use these procedures beacause they are specific to 
DCOracle2 driver only, so when I'll want to move to SQLRelay for example 
it will be not possible to transfer it easily. We have some problems 
with our DBConnections and DCOracle2 is suspected and more: there were 
problems with installing DCOracle2 on Mainframe machine, so I want to 
test SQLRelay.

Yes... maybe writing own product will be a good idea.
