Subject [jira] Commented: (OPENJPA-817) Order of inserts lost when using ConstraintUpdateManager
Date Fri, 05 Dec 2008 23:05:44 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-817?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12653968#action_12653968
] 

Michael Dick commented on OPENJPA-817:
--------------------------------------

Didn't notice the changes to ConstraintUpdateManager in 1.3.x and trunk which affect this
issue. It looks like I missed a relevant spot in those releases, but since it's late on Friday
I'm reverting the changes until I have more time to figure out the right solution. 

The fix for 1.2.x seems consistent (at least to my ability to test it so I'm leaving it alone
for now).

> The ConstraintUpdateManager does a good job of ordering inserts, updates and deletes
when the internal metadata is complete. If the internal metadata is not complete (ie there
are no @ForeignKey annotations) SQL statements are executed in an arbitrary order. 
> The application can avoid this by adding the appropriate annotations, or by obtaining
the data from the database, but we can make some attempt to preserve the order of execution.
