【问题描述】:
我在将 FOREIGN KEY 添加到表 catalog_produt_flat_8 - Magento 1.9 时遇到问题
当我尝试重新索引时
Product Flat Data index process unknown error:
exception 'PDOException' with message 'SQLSTATE[23000]: Integrity constraint violation: 1022 Can't write; duplicate key in table '#sql-4c36_d67'
我尝试在 MySQL 中添加
ALTER TABLE catalog_product_flat_8
ADD CONSTRAINT FK_CAT_PRD_FLAT_8_ENTT_ID_CAT_PRD_ENTT_ENTT_ID FOREIGN KEY (entity_id) REFERENCES catalog_product_entity (entity_id) ON DELETE CASCADE ON UPDATE CASCADE;
还是
1022 Can't write; duplicate key in table '#sql-4c36_1099
我签入 information_schema
SELECT * FROM information_schema.REFERENTIAL_CONSTRAINTS WHERE CONSTRAINT_SCHEMA = "magento_db" AND CONSTRAINT_NAME LIKE "FK_CAT_PRD_FLAT_8_ENTT_ID_CAT_PRD_ENTT_ENTT_ID"
但有 0 条记录
select COLUMN_NAME, CONSTRAINT_NAME, REFERENCED_COLUMN_NAME,
REFERENCED_TABLE_NAME
from information_schema.KEY_COLUMN_USAGE
where TABLE_NAME = 'catalog_product_flat_8';
我只有 entity_id 的主键
所以,我检查一下:
select *
from information_schema.table_constraints
where constraint_schema = 'magento_db'
entity_id (PRIMARY) 中只有 1 条记录为“flat_8”,
我在 information_schema 的每个表中搜索“FK_CAT_PRD_FLAT_8_ENTT_ID_CAT_PRD_ENTT_ENTT_ID”
结果:
`information_schema`.`INNODB_SYS_FOREIGN`
| ID |FOR_NAME |REF_NAME | N_COLS | TYPE |
| magento_db/FK_CAT_PRD_FLAT_8_ENTT_ID_CAT_PRD_ENTT_E... |magento_db/#sql-6756_19e0f | magento_db/catalog_product_entity | 1 | 5 |
`information_schema`.`INNODB_SYS_FOREIGN_COLS`
| ID | FOR_COL_NAME| REF_COL_NAME | POS |
| magento_db/FK_CAT_PRD_FLAT_8_ENTT_ID_CAT_PRD_ENTT_E... | entity_id | entity_id | 0 |
我不知道,请帮忙
