EDIT

maybe related to #2448

An empty fullTitleCache with atomized data was not found anywhere. Empty fullTitleCaches exist for fully empty data which have something like TaxonName#9617 in the titleCache. So empty fullTitleCaches are not replaced by this default yet. But maybe this is also not necessary.

Only in algaterra_old I found records with also empty titleCache which needs to be further checked. Even after running cacheUpdate and trying to edit the names manually.

SELECT id, protectedTitleCache, protectedFullTitleCache, titleCache, fullTitleCache , tn.*
    FROM TaxonName tn
    WHERE tn.titleCache IS NULL OR tn.titleCache = '' OR tn.fullTitleCache IS NULL OR tn.fullTitleCache = ''
    ;

    SELECT *
    FROM OriginalSourceBase osb
    WHERE osb.sourcedName_id IN (
    SELECT id
    FROM TaxonName tn
    WHERE tn.titleCache IS NULL OR tn.titleCache = '' OR tn.fullTitleCache IS NULL OR tn.fullTitleCache = ''
) ;

Also in Flora Malesiana after running cache update (#9650).

Pro-iBiosphere eupolybothrus_pilot has empty titleCache with atomized data but this has no CDM Server anymore and was not yet cache updated. => the DB is archived in the meanwhile.

Also rl_standardliste has them but was not yet cache udpated. => do not exist anymore after cache updating (#9650)
