Check Link Table Deleted

The common reason why soft delete did not have effect is that several DEFs have been created with the same Date of Information.

SELECT
"public".link.from_guid,
"public".link.from_link_type,
"public".link.to_link_type,
"public".link.to_guid,
"public".link.update_type,
"public".link.deleted,
"public".link.data_entry_date
FROM
"public".link
WHERE
"public".link.update_type = 'DELETE' AND
"public".link.deleted = 'f' 
ORDER BY
"public".link.from_link_type ASC
