--- Fix Foreign Key Constraints für Multi-Document-Support
--- Diese Felder sollten NULL sein können, da eine Section entweder zu einer
--- Rechnung ODER einem Angebot ODER einem Auftrag gehört, aber nie zu allen gleichzeitig.
-
--- 1. Foreign Key Constraints temporär entfernen
-ALTER TABLE llx_facture_lines_manager DROP FOREIGN KEY IF EXISTS `1`;
-ALTER TABLE llx_facture_lines_manager DROP FOREIGN KEY IF EXISTS `2`;
-ALTER TABLE llx_facture_lines_manager DROP FOREIGN KEY IF EXISTS `3`;
-ALTER TABLE llx_facture_lines_manager DROP FOREIGN KEY IF EXISTS `fk_facture_lines_manager_facture`;
-ALTER TABLE llx_facture_lines_manager DROP FOREIGN KEY IF EXISTS `fk_facture_lines_manager_propal`;
-ALTER TABLE llx_facture_lines_manager DROP FOREIGN KEY IF EXISTS `fk_facture_lines_manager_commande`;
-
--- 2. Felder auf NULL ändern
-ALTER TABLE llx_facture_lines_manager
-  MODIFY COLUMN fk_facture INT NULL DEFAULT NULL,
-  MODIFY COLUMN fk_propal INT NULL DEFAULT NULL,
-  MODIFY COLUMN fk_commande INT NULL DEFAULT NULL;
-
--- 3. Foreign Key Constraints wieder hinzufügen (mit ON DELETE CASCADE)
-ALTER TABLE llx_facture_lines_manager
-  ADD CONSTRAINT fk_facture_lines_manager_facture
-  FOREIGN KEY (fk_facture) REFERENCES llx_facture(rowid) ON DELETE CASCADE;
-
-ALTER TABLE llx_facture_lines_manager
-  ADD CONSTRAINT fk_facture_lines_manager_propal
-  FOREIGN KEY (fk_propal) REFERENCES llx_propal(rowid) ON DELETE CASCADE;
-
-ALTER TABLE llx_facture_lines_manager
-  ADD CONSTRAINT fk_facture_lines_manager_commande
-  FOREIGN KEY (fk_commande) REFERENCES llx_commande(rowid) ON DELETE CASCADE;
