Solve the problem when setting the date to 0000-00-00 00:00:00 in MySQL 8.0.13

I just started learning database operations. Today, when I was saving data, I found that an error occurred (Error 1292: Incorrect datetime value: '0000-00-00' for column 'deleted_at' at row 1) . Then I searched for the reason and found that it was because MySQL did not allow this format when storing dates. The following is a record of the process of solving the problem:

First, according to the Mysql database date, datetime type setting 0000-00-00 default value error problem this blog operation. But found out. I don't have the cnf file mentioned in the article on my computer. So I searched for the file online. Paste the contents of my.cnf into /etc/my.cnf .
But wait I will

When pasting to the location of the file, it still fails. MySQL cannot be started directly. Later, when I set sql_mode in the command line, I saw an error message:

mysql> SET GLOBAL sql_mode = 'ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
ERROR 1231 (42000): Variable 'sql_mode' can't be set to the value of 'NO_AUTO_CREATE_USER'

ERROR 1231 (42000): Variable 'sql_mode' can't be set to the value of ' NO_AUTO_CREATE_USER ' means that NO_AUTO_CREATE_USER cannot be set. Then don’t set it. Then remove the sql-mode line in the my.cnf file and change the value successfully.

MySQL version: 8.0.13

The above is the full content of this article. I hope it will be helpful for everyone’s study. I also hope that everyone will support 123WORDPRESS.COM.
