Fix Version/s: 1.5
As we discussed, there are extraneous duplicate civicrm_contact, civicrm_organization and civicrm_relationship records representing students' High School and Other School info in the production data (due to bugs in Highschool.php and OtherSchool.php form logic).
We need a PHP script we can run from command line against a production data set which locates duplicate records based on the following "key"
civicrm_contact.id (type = Individual) +
civicrm_relationship (WHERE relationship_type_id = 8 & contact_a_id = individual's contact_id & start and end dates are the same) +
civicrm_custom_value.char_data (WHERE entity_table=civicrm_contact & entity_id = school's contact_id & custom_field_id = 4)
From the duplicate record set for a given Student (contact Individual) - delete all dupes except the set with the highest civicrm_relatiionship.id value (which is the last "set" to be inserted).
NOTE: Script should be able to be run repeatedly against the same data w/o destroying NON-duplicate records.
