Subject [jira] Commented: (OPENJPA-1720) MappingTool does not add version column for subclass
Date Tue, 28 Sep 2010 17:33:32 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1720?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12915847#action_12915847

Fay Wang commented on OPENJPA-1720:
-----------------------------------

Hi Howard,
With Joined table strategy, any update in Child will involve two update because the version
column is in the parent table, and the child field is in the Child table. This is working
as design. If you want to avoid the extra overhead, you can use SINGLE Table strategy.
