The solution of error “ERROR 1067 (42000) at line 211: Invalid default value for ‘blablabla'”

I noticed once when importing a sql file the following error:

ERROR 1067 (42000) at line 211: Invalid default value for ‘blablabla’

It arises because new versions of MySQL server use strict mode and parameters such as NO_ZERO_DATE do not allow entering date values like ‘0000-00-00’ into the database.

Connect to mysql server:

mysql -u root -p

Execute a query that displays the values of sql_mode:

show variables like 'sql_mode';

Copy the string with these values and exit mysql:

exit

Open the configuration file for example in the text editor nano (Ctrl+X for exit, y/n for saving or canceling the changes):

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

I did not have sql_mode = in the file, so at the end of the file I inserted the line with the previously copied values, removing NO_ZERO_IN_DATE, NO_ZERO_DATE from it, in my case, the following happened:

sql_mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

Restart mysql to apply the changes:

sudo service mysql restart

Done, now when importing this error should not be.
