Mysql之修改表的编码字符集

--改变表的编码，为utf8mb4

alter table `someabcd_cms`   convert to character set  utf8mb4;

除此之外还需要注意配置文件相关的支持

[client] 

default-character-set = utf8mb4 

[mysql] 

default-character-set = utf8mb4 

[mysqld] 

character-set-client-handshake = FALSE 

character-set-server = utf8mb4 

collation-server = utf8mb4_unicode_ci 

init_connect='SET NAMES utf8mb4'
