mysql Error : Cannot truncate a table referenced in a foreign key constraint 清空具有外键约束的表时报

在清除mysql表数据时报错：

DELETE from weshares where id >0;truncate table weshares; drop

以上方式清楚表数据的时候都报以下错误：

Error : Cannot truncate a table referenced in a foreign key constraint (`distribution`.`weshare_delivery_templates`,

CONSTRAINT `fk_weshare_delivery_templates_weshares` FOREIGN KEY (`weshare_id`) REFERENCES `distribution`.`weshares` (`id`))

原因：清空具有外键约束的表就会报错

解决方法：

SET FOREIGN_KEY_CHECKS = 0; //先归0TRUNCATE table1; //在清除数据SET FOREIGN_KEY_CHECKS = 1; //能后设置1
