Upgrading civicrm 1.9 to 2.0, FK constraint issue.
May 10, 2012, 03:21:42 pm
I am working on a civi 1.9 install trying to upgrade to version 2.0, ultimately I want to upgrade to 4.1.  I followed the instructions for the 1.9=>2.0 upgrade and when running the upgrade script step 4, I get foreign key constraint errors.  Here is the exact error:

Sorry. A non-recoverable error has occurred.
Database Error Code: Cannot add or update a child row: a foreign key constraint fails (idfcrm_1dot9.civicrm_activity_target, CONSTRAINT FK_civicrm_activity_target_target_contact_id FOREIGN KEY (target_contact_id) REFERENCES civicrm_contact (id) ON DELETE CASCADE), 1452

I couldn't post the error dump directly in here, the forum complains about external links???
Here is a link to a google doc with the data dump.
docs.google.com/document/d/1sdRr4Mhuq1ZzyoVW_daTO5ceMq8QdNq6ZRBeYuEWqK0/edit


I tried searching the database to find the fk constraint issues and can't find anything.  I did find 1 where civicrm_activity.source_contact_id = 0, and there was no contact with an id of 0.  But I can't find any constraints related to the civicrm_activity_target table.

Any help with this is appreciated.
Thanks,
Ian Herbert

That error means that the field target_contact_id must match the id of a contact. It sounds like you may have a lot of those set to zero then. Hard to say without seeing the DB. Perhaps a "kludge" solution would be to manually create a contact with an id of zero....
