Eric, Which version of the driver are you using? Also do you have logs from the postgres backend? My suspicion is something in the data is causing the problem, what I don't know, but that's my guess. Dave -----Original Message----- From: pgsql-jdbc-owner@postgresql.org [mailto:pgsql-jdbc-owner@postgresql.org] On Behalf Of Eric Scroger Sent: Tuesday, March 05, 2002 5:28 PM To: pgsql hackers; pgsql-jdbc@postgresql.org Cc: ed@carl.org Subject: [JDBC] A result was returned by the statement, when none was expected JDBC-ers, We are doing an INSERT and occasionally Postgres throws a SQLException because there are unexpected results (see stacktrace below), maybe 10% of the time, Any idea why this would happen when it works over 90% of the time? However, it appears the insert is completed successfully. We have looked at the source code for ResultSet.java and noticed the method reallyResultSet() returns true if any of the fields are non-null. I hope that helps in debugging. Also, we are running Postgres 7.1 with JDK1.2.1.
