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’。

做了记录以备之后遇到。

root@localhost:~# mysql -u root -p
Enter password:

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> set global sql_mode='ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'
    -> ;
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> commit;

root@localhost:~#

完成之后再重建数据库,就能导入了。
