MySql 安装相关记录【持续更新】

1.导出sql报错：currenttimestamp出错

解决方案：

CREATE TABLE `product_category` (
  `category_id` int NOT NULL AUTO_INCREMENT,
  `category_name` varchar(64) NOT NULL COMMENT '类目名称',
  `category_type` int NOT NULL COMMENT '类目编号',
  `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `update_time` timestamp NOT NULL  COMMENT '更新时间',
   PRIMARY KEY (`category_id`)
) 
 
 
 
CREATE TRIGGER `update_product_category_trigger` BEFORE UPDATE ON `product_category`
 FOR EACH ROW SET NEW.`update_time` = NOW()
