utf8mb3是为了兼容之前版本的MySQL,将utf8与utf8mb4区分开来的别名。在MySQL 5.7及以后的版本中,建议使用utf8mb4字符集作为默认字符集,以便支持更多的字符。但是,在一些场景中,仍然需要使用utf8或utf8mb3字符集,例如与旧代码或旧数据库进行兼容性测试。 在character_set_server和collation_server参数...
谢谢老师,我在看mysql8版本里面,默认设置的为character_set_server = utf8mb4和collation_server = utf8mb4_0900_ai_ci,这是不是说明这种方式更值得使用和更优?还有我在以前5.7版本数据库里面为utf8和utf8_general_ci,在换新版本的时候,换成utf8mb4和utf8mb4_0900_ai_ci,这样会对数据有影响吗? 回复 20...

(E.g. my.ini), hence the error when restarting the service is expected. Optionally you can set it by running a SET command such as "SET default_collation_for_utf8mb4 = utf8mb4_0900_ai_ci". Note that you will get a warning since the variable is intended for internal use only as...
