Subject [jira] Created: (OPENJPA-435) Change mapping defaults to assume foreign keys exist for relationships by default
Date Tue, 06 Nov 2007 17:10:50 GMT
Change mapping defaults to assume foreign keys exist for relationships by default
---------------------------------------------------------------------------------

                 Key: OPENJPA-435
                 URL: https://issues.apache.org/jira/browse/OPENJPA-435
             Project: OpenJPA
          Issue Type: Improvement
          Components: sql
    Affects Versions: 1.0.0, 0.9.7, 0.9.6, 0.9.0, 1.0.1, 1.0.2, 1.1.0
            Reporter: Patrick Linskey
             Fix For: 1.1.0


OpenJPA's current defaults assume that no foreign keys exist. This leads to potentially more
optimal SQL ordering, but often also leads to FK constraint violations when obvious FKs exist
but are not declared. We should change this default to be more user-friendly, and add a note
to our optimization guide as appropriate if there are actions users should take to optimize.
