Adding columns NAME and CONTEXT (the two parts of the key) did not help. Adding the oid column makes it work. I have a problem with this, however, since this code has to also run against Oracle and MSSQL. Is there another answer? -----Original Message----- From: Dave Cramer [mailto:Dave@micro-automation.net] Sent: Wednesday, March 19, 2003 7:19 PM To: David Hooker Cc: pgsql-jdbc@postgresql.org Subject: Re: [JDBC] Problem with updateRow() David, The updateable result set is really only supported for very simple tables, and keys, I suppose it could deal with composite keys, but this isn't the intention AFAIK. At the very least you would have to select both columns of the key to have it work though. There is a simple solution for you however, add the oid to your select. ie select oid, filename, ... and let me know if it works.
