Subject [jira] Updated: (DERBY-3310) ASSERT in MergeSort.checkColumnTypes() disallow legal type conversions
Date Thu, 28 Feb 2008 22:13:51 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3310?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kathey Marsden updated DERBY-3310:
----------------------------------

    Attachment: derby-3310_remove_genNormalizeResultSetNode_diff.txt

The attached patch derby-3310_remove_genNormalizeResultSetNode_diff.txt moves the contents
of ResultSetNode.genNormalizeResultSetNode into NormalizeResultSetNode.init() method.  The
method still copies the ResultColumnList as before.

I had a harder time with getting rid of copyTypesAndLengthsToSource, so decided to wait for
a second patch for removing that method. I'll post some questions about that after this patch
gets committed.
