bug #6705
Updated by Andreas Müller almost 7 years ago
There are PKN left that are linked to an existing key but have no parent but link to a taxon (so are no root nodes).
~~~ sql
SELECT *
FROM PolytomousKeyNode pkn
WHERE pkn.parent_id IS NULL
AND pkn.taxon_id IS NOT NULL
~~~
Check carefully that they are not linked as parents and that they are not root nodes. Maybe run recursively until none is left.
Also use the script used in #6226 to remove orphaned KeyStatements afterwards.
There are 16 examples in cyprus.
