mysql表注释乱码

问题

• 执行语句: alter table TABLE_XXX comment ‘中文号’;
• 结果: use information_schema;
  
  1. select * from TABLES where TABLE_SCHEMA=’mydb’ and TABLE_NAME=’TABLE_XXX’
  2. TABLE_XXX 的注释为乱码

检查系统

• 用show variables like “%colla%”；show varables like “%char%”；这两条命令查看数据库与服务端的字符集设置

修改

• set collation_server=utf8_general_ci;
• set collation_connection=utf8_general_ci;
