Niels, thank you very much for your help. How can I access this bat, when I start a new session? bat.load("person_name"); doesn't seem to work. io.print(n): ERROR = !TypeException:user.main[1]:'n' may not be used before being initialized Thanks Kambiz ----- Original Message ----- From: "Niels Nes" To: darabi@web.de Cc: monetdb-developers@lists.sourceforge.net Sent: Donnerstag, 11.

Hello,
sorry for asking so many dumb questions, but I don't seem to be able to find the answers in the docs.
I try to create and persist a bat:
(mclient -d demo -l mal)
n := bat.new(:oid,:str); bat.setName(n, "person_name"); bat.setPersistent(n, true);
bat.append(n, "John", true); bat.append(n, "James", true);
replace this save
bat.save(n); by
transaction.commit(); Niels (ps later you probably want to switch to subcommit, ie only commit those bat that changed, for this see the documenation in the transaction module (src/modules/mal/transaction.mx)
But this doesn't seem to be sufficient.
Or at least I then don't know how to load this bat the next time I start mclient.
Is there a file (one of the tests or sth.) which contains such basic tests? I tried to find-grep over them, but didn't succeed in finding what I was looking for.
