[jira] [Commented] (CALCITE-3155) AssertionError in
RelToSqlConverter when visiting empty Values node
[ https://issues.apache.org/jira/browse/CALCITE-3155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16875628#comment-16875628 ]
Julian Hyde commented on CALCITE-3155:
--------------------------------------
With its use of the DUAL table, the fix is far too dependent on oracle. I would like to see this problem solved for several databases simultaneously. I think it would lead to better code structure.
