Subject [jira] Commented: (DERBY-4439) NullPointerException at bind time when selecting from VALUES NULL
Date Mon, 09 Nov 2009 19:47:32 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4439?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12775094#action_12775094

Mamta A. Satoor commented on DERBY-4439:

Another thing that can be pursued is to see if genSQLJavaSQLTree() can be called after all
the binding is finished(including the untyped nulls).
