之前将mysql的数据版本从5.6升级到了5.7,导入备份的数据库的时候,若时间的默认值为零会报错Error : Invalid default value for ‘comment_date’。后来有从5.7升级到了8.0,同样有这个问题。
做了记录以备之后遇到。
5.6->5.7

5.7->8.0 服务器系统是Debian,同时使用了Docker。
root@localhost:~# docker exec -it db mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 471 Server version: 8.0.27 MySQL Community Server - GPL Copyright (c) 2000, 2021, Oracle and/or its affiliates.

完成之后再重建数据库,就能导入了。
