Subject [jira] Commented: (OPENJPA-1514) DBDictionary instances do not call setAutoAssigned() where appropriate
Date Thu, 25 Feb 2010 17:57:27 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1514?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12838445#action_12838445

Laird Nelson commented on OPENJPA-1514:
---------------------------------------

Hi, Fay; they certainly do in Java 6.  See the IS_AUTOASSIGNED value in the ResultSet returned
by getColumns().

Also, the use case I am looking at is going the "other way": from a SchemaGenerator through
to the ReverseMappingTool.  I need the ReverseMappingTool to be able to output @GeneratedValue
where appropriate.

> Although a DBDictionary instance by definition has access to the database's information
that would allow it to mark a new Column as being autoassigned, DBDictionaries do not do this
in their newColumn() method.  It seems to me that all DBDictinonary instances should be required
by contract to detect when a column is a database-managed identity or sequential column and
should call Column#setAutoAssigned(boolean) as appropriate.
