;##重啟mysql服務
sudo service mysql restart

官方解釋：在5.x版本的mysql對空值插入有」bug」,要在安裝mysql的時候去除預設勾選的enable strict sql mode,如果我們安裝好了mysql，解決辦法是更改mysql中的配置 my.ini

my.ini中查詢sql-mode，

預設為:sql-mode=」strict_trans_tables,no_auto_create_user,no_engine_substitution」，將其修改為
sql-mode=no_auto_create_user,no_engine_substitution
重啟mysql後即可

my.cnf檔案內只有

!includedir /etc/mysql/conf.d/

!includedir /etc/mysql/mysql.conf.d/

sql

-mode
=no_auto_create_user,no_engine_substitution
