Tariq

Yes - it allows multiple copies of the same primary key. See

http://instantdb.enhydra.org/project/faq/index.html

for details. I suspect that some day this will become an option and the default will be to
enforce PK uniqueness.

If you did your rollback in auto-commit mode then it will indeed have no effect. You need
to add the line:

c autocommit off;

to your script before doing the insert, or call Connection.setAutoCommit (false) if doing
it from code.
