doctrine:schema:update deleting Pimcore tables

[SaschaHowe]

Hey,

we've a strange problem with form builder 5.3 and doctrine:orm 3.4

When we execute a doctrine:schema:update most of the Pimcore tables are dropped.

DROP TABLE redirects;
DROP TABLE targeting_storage;
DROP TABLE edit_lock;
DROP TABLE tree_locks;
DROP TABLE object_url_slugs;
DROP TABLE application_logs;
DROP TABLE documents_hardlink;
DROP TABLE lock_keys;
DROP TABLE gridconfigs;
DROP TABLE documents_snippet;
DROP TABLE documents_link;
DROP TABLE classificationstore_keys;
DROP TABLE notes;
DROP TABLE objects;
DROP TABLE translations_admin;
DROP TABLE translations_messages;
DROP TABLE tags_assignment;
DROP TABLE element_workflow_state;
DROP TABLE notifications;
DROP TABLE dependencies;
DROP TABLE targeting_rules;
DROP TABLE assets_metadata;
DROP TABLE users_workspaces_document;
DROP TABLE documents_translations;
DROP TABLE documents;
DROP TABLE targeting_target_groups;
DROP TABLE documents_editables;
DROP TABLE classificationstore_relations;
DROP TABLE gridconfig_favourites;
DROP TABLE properties;
DROP TABLE classes;
DROP TABLE classificationstore_collectionrelations;
DROP TABLE tags;
DROP TABLE website_settings;
DROP TABLE users;
DROP TABLE http_error_log;
DROP TABLE gridconfig_shares;
DROP TABLE users_workspaces_asset;
DROP TABLE importconfigs;
DROP TABLE users_workspaces_object;
DROP TABLE sites;
DROP TABLE search_backend_data;
DROP TABLE documents_page;
DROP TABLE quantityvalue_units;
DROP TABLE settings_store;
DROP TABLE recyclebin;
DROP TABLE documents_email;
DROP TABLE assets_image_thumbnail_cache;
DROP TABLE notes_data;
DROP TABLE schedule_tasks;
DROP TABLE assets;
DROP TABLE classificationstore_collections;
DROP TABLE webdav_locks;
DROP TABLE versions;
DROP TABLE importconfig_shares;
DROP TABLE tmp_store;
DROP TABLE users_permission_definitions;
DROP TABLE email_log;
DROP TABLE classificationstore_groups;
DROP TABLE classificationstore_stores;
DROP TABLE email_blocklist;

This is not happening, when we downgrade doctrine/orm to 2.20.4, or when we disable the form builder bundle.
Any idea what could be the reason for this?

Greetings,
Sascha

That's because pimcore is not using doctrine managed entities and with ORM 3, the --complete argument is enabled by default.

Pimcore fixed this within v12, which is a version we don't support: pimcore/pimcore#18253
