Subject [jira] Commented: (CONTINUUM-1787) cannot delete a project, constraint violation
Date Thu, 20 Nov 2008 16:28:41 GMT

    [ http://jira.codehaus.org/browse/CONTINUUM-1787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=154903#action_154903
] 

Geert Pante commented on CONTINUUM-1787:
----------------------------------------

I found there were three foreign key constraints on the PROJECT table
CONSTRAINT PROJECT_FK1 FOREIGN KEY (PARENT_PROJECTDEPENDENCY_ID_OID) REFERENCES PROJECTDEPENDENCY
(PROJECTDEPENDENCY_ID);
CONSTRAINT PROJECT_FK2 FOREIGN KEY (PARENT_PROJECTDEPENDENCY_ID_OID) REFERENCES SCMRESULT
(SCMRESULT_ID);
CONSTRAINT PROJECT_FK3 FOREIGN KEY (PARENT_PROJECTDEPENDENCY_ID_OID) REFERENCES PROJECTGROUP
(ID);

I updated the first constraint to 'ON DELETE SET NULL', and dropped the two others, so now
it works. 
I have no idea what PROJECT_FK2 and PROJECT_FK3 are supposed to do. I only found in continuum-model
JPOX config file:
    <class>
      <name>Project</name>
      <version>1.0.9+</version>
      <fields>
[...]
     <field jpox.fetch-groups="project-all-details project-dependencies">
          <name>parent</name>
          <version>1.0.9+</version>
          <association jpox.join="false">
            <type>ProjectDependency</type>
          </association>
        </field>

caused a violation of foreign key constraint 'PROJECT_FK2' for key (1219321). The statement
has been rolled back.
