Duplicates (for eventual correction) can be found by running a report: SELECT GROUP_CONCAT(biblionumber SEPARATOR ', ') AS biblionumbers, EXTRACTVALUE(marcxml,'//controlfield[@tag="001"]') AS id FROM biblioitems GROUP BY id HAVING count(id) > 1 -- You are receiving this mail because: You are watching all bug changes.
