Hello, I am trying to use MonetDB as a backend for Java application I am developing. I have noticed that inserts the application does have no effect. Statements are executed without exceptions, but data rows do not get into table. I have investigated the problem and have figured out that problem is in transaction and savepoint handling. If transaction had savepoints, it could be silently rolled back when Connection.commit() is called. I have finished with short Java program that demonstrate the bug(?), I am attaching it to the message. Please, take a look. I tested with MonetDB-4.8.2+sql-2.8.2 (release, source tarball) and with MonetDB-4.8.3+sql-2.8.3 (nightly build, August 30). Platforms: 32-bit Linux RedHat 9, 32-bit Linux Ubuntu 5.04 -- Best regards, Andrei Martsinchyk mailto:andrei.martsinchyk@gmail.com
