MySQL error code 1217 (ER_ROW_IS_REFERENCED): Cannot delete or update a parent row: a foreign key co

环境介绍：

CentOS 6.7

数据库版本：MariaDB10.0.21

在删除一张有主键的表时，直接抛出错误“ERROR 1217 (23000): Cannot delete or update a parent row: a foreign key constraint fails”

解决办法：临时停止主键检查

MariaDB [d]> SET FOREIGN_KEY_CHECKS = 0;

MariaDB [d]> drop table actions;

MariaDB [d]> SET FOREIGN_KEY_CHECKS = 1;
