Constraint Violation when importing event participants
July 14, 2014, 10:32:55 pm
When importing some event participants, I get a constraint violation error (backtrace)

When I try inserting a row in the civicrm_participant table using this query:
Code: [Select]
INSERT INTO `reachov5_CiviCRM`.`civicrm_participant` (`id`, `contact_id`, `event_id`, `status_id`, `role_id`, `register_date`, `source`, `fee_level`, `is_test`, `is_pay_later`, `fee_amount`, `registered_by_id`, `discount_id`, `fee_currency`, `campaign_id`, `discount_amount`, `cart_id`, `must_wait`) VALUES (NULL, '714', '9', '2', '1', NULL, NULL, NULL, '0', '0', NULL, '637', NULL, NULL, NULL, NULL, NULL, NULL)

I get a MySQL error:
Code: [Select]
#1452 - Cannot add or update a child row: a foreign key constraint fails (`reachov5_CiviCRM`.`civicrm_participant`, CONSTRAINT `FK_civicrm_participant_registered_by_id` FOREIGN KEY (`registered_by_id`) REFERENCES `civicrm_participant` (`id`) ON DELETE SET NULL)

I've checked that the registered_by_id value is a valid contact (organization) and the contact_id is valid (individual). Also the event_id, status_id and role_id are valid.

This doesn't happen when adding all participant but just some. I thought that the problem occurs when the registered_by contact has a contact_sub_type other than null but now I don't know for sure that is the case.

Any help would be appreciated. I has me stopped in my track with another 2000 participants to import.

Thanks

Re: Constraint Violation when importing event participants

I have some new information that might help:

At least in this particular case the participant I'm importing, 714, has a relationship with contact 637 (is an employee of the organization 637). Contact 637 is the registered_by_id. What I'm trying to indicate here is that the employee was registered for the event by his employer. Is that a problem or is there a different way of doing it?
