mysql - 无法添加或更新子行: a foreign key constraint fails in magetno

Question

我正在尝试使用 phpmyadmin 导入 sql 转储。 我收到以下错误

表catalog_compare_item的约束

ALTER TABLE `catalog_compare_item`
ADD CONSTRAINT `FK_MAG_CATALOG_COMPARE_ITEM_STORE_ID_MAG_CORE_STORE_STORE_ID` FOREIGN KEY (`store_id`) REFERENCES `core_store` (`store_id`) ON DELETE SET NULL ON UPDATE CASCADE,
ADD CONSTRAINT `FK_MAG_CAT_CMP_ITEM_CSTR_ID_MAG_CSTR_ENTT_ENTT_ID` FOREIGN KEY (`customer_id`) REFERENCES `customer_entity` (`entity_id`) ON DELETE CASCADE ON UPDATE CASCADE,
ADD CONSTRAINT `FK_MAG_CAT_CMP_ITEM_PRD_ID_MAG_CAT_PRD_ENTT_ENTT_ID` FOREIGN KEY (`product_id`) REFERENCES `catalog_product_entity` (`entity_id`) ON DELETE CASCADE ON UPDATE CASCADE;

#1452 - Cannot add or update a child row: a foreign key constraint fails (`checktest`.`#sql-c74_23`, CONSTRAINT `FK_MAG_CAT_CMP_ITEM_CSTR_ID_MAG_CSTR_ENTT_ENTT_ID` FOREIGN KEY (`customer_id`) REFERENCES `customer_entity` (`entity_id`) ON DELETE CASCADE ON UPDATE CAS) 

Answer 1

您应该尝试在禁用 session 的外键检查约束后进行导入。

SET FOREIGN_KEY_CHECKS=0;

将以上行放在您要导入的 sql 转储的顶部，然后再次尝试导入。
