Thanks Sebastian,
Changes to this file had not been committed to CVS for some reason. A change similar to what you suggest is now there. As this file is JDK 1.4 specific due to the use of a new JDBC interface, it won't compile under 1.3.
Also, the Sourceforge listserver seems to be erratic. I received your post less than an hour ago, although you sent it over 20 hours ago.
The current CVS head contains updates to ON DELETE CASCADE to work with chained same-table references.
Seems to work on standard table, but still crashes on CACHED tables.
Cheers S.

Hi
Tried to build a freshly fetched hsqldb-dev with JDK 1.4.2 but it failes with
<snip> Rebuilding EchoProperty.class... Building for target '1.4' (Resultant jar can only be used with Java JREs >= 1.4) Running CodeSwitcher... Rebuilding CodeSwitcher.class...

It actually seems that these variables are not a member of org.hsqldb.Result but of the inner class ResultMetaData. If I change 'r.' tp 'r.metaData' it works fine. Although this kind of external access to a internal class member seems to be ugly ....
What does JAVA 1.3 do ? Silently resolve the name r.isIdentity to r.metaData.isIdentity ? (Uuuuhh that's even more spooky..)
Cheers
