Subject svn commit: r831319 - /db/derby/code/trunk/java/testing/org/apache/derbyTesting/functionTests/tests/lang/GeneratedColumnsTest.java
Date Fri, 30 Oct 2009 15:08:11 GMT

New Revision: 831319

URL: http://svn.apache.org/viewvc?rev=831319&view=rev
Log:
DERBY-4425: NPE with INSERT .. SELECT .. UNION and generated expressions

This patch adds a test which confirms that DERBY-4425 is fixed. The code
change which resolved DERBY-4425 was performed as part of fixing DERBY-4419,
since the same code change fixes both symptoms, so this is a test-only patch.

subversion revision 831304 contains the DERBY-4419 code change.
