Not sure. Strange here is that no delete event exists in TaxonName_AUD. However, in TaxonName the object does not exist anymore.

2 taxa exist that did use the name: taxon 33986 (deleted with REV 53772) and synonym 38657 (created with same REV 53772 and deleted with REV 53790).

This may happen when only the AUD event fails to commit and an exception is thrown instead. We also need to handle this case somehow (if a failing audit event commit is the reason).

SELECT *
FROM TaxonName_AUD tn
WHERE tn.id = 32296

SELECT *
FROM TaxonName tn
WHERE tn.id = 32296

SELECT ev.*, tb.*
FROM TaxonBase_AUD tb INNER JOIN AuditEvent ev ON ev.revisionnumber = tb.REV
WHERE tb.name_id = 32296 OR tb.id IN (33986, 38657)
ORDER BY tb.id

NOTE: A general problem or caveat of the data in the audit tables are lacking a timestamp of the operation and of the user which was responsible.

timestamp is available when joining with AuditEvent table, for responsible user a new ticket has been created: #7604
