1.由于sql_mode 中设置no_zero_in_date 导致的错误

Executing:
CREATE TABLE `miaosha`.`new_table` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `promo_name` VARCHAR(45) NOT NULL DEFAULT '',
  `start_date` DATETIME NOT NULL DEFAULT '0000-00-00 00:00:00',
  `item_id` INT NOT NULL DEFAULT 0,
  `promo_item_price` DOUBLE NOT NULL DEFAULT 0,
  PRIMARY KEY (`id`));

Operation failed: There was an error while applying the SQL script to the database.
ERROR 1067: Invalid default value for 'start_date'

在终端连接mysql后，输入命令

select @@sql_mode;

正是红圈导致出错

mysql 8.0.20中一旦修改my.ini文件，就需要重新新建mysql服务
