Subject [jira] Commented: (DERBY-268) Add Support for truncate table
Date Fri, 11 Feb 2011 17:17:57 GMT

    [ https://issues.apache.org/jira/browse/DERBY-268?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12993589#comment-12993589

Rick Hillegas commented on DERBY-268:
-------------------------------------

Hi Eranda,

The idea is that the table element representing the RESTART action should be added at bind()
time, not at parse() time. All that happens at parse() time is that you mark the AlterTableNode
to note that the user has requested RESTART. The new tableElement should be added at bind()
time. At bind() time you will have access to all of the metadata you need and you should be
able to find the name of the identity column in structures hanging off the TableDescriptor.
You should build the tableElement in AlterTableNode.bind(). See my comment on 2010-11-18 for
the processing flow.

Hope this helps,
-Rick
