Löschen aller Produkte und Kategorien in Woocommerce

ACHTUNG!!! Wie immer, vorher Backup erstellen!

Gegebenfalls bitte das Tabellen-Prefix ändern. (Ersetze wp_ durch EuerPrefix_)

Viel Spaß beim Nachkochen.

FROM wp_term_relationships AS relations
INNER JOIN wp_term_taxonomy AS taxes
ON relations.term_taxonomy_id=taxes.term_taxonomy_id
INNER JOIN wp_terms AS terms
ON taxes.term_id=terms.term_id
WHERE object_id IN (SELECT ID FROM wp_posts WHERE post_type IN ('product','product_variation'));

DELETE FROM wp_postmeta WHERE post_id IN (SELECT ID FROM wp_posts WHERE post_type IN ('product','product_variation'));
DELETE FROM wp_posts WHERE post_type IN ('product','product_variation');
