— 插入中文字符
insert into tb_teacher (name, age) values (‘张三’, 23);

set 变量名 = 值;
— 修改单个变量
set character_set_client = gbk;
— 设置字符集
set names gbk;
— 等价于
set character_set_client = gbk; // 让服务器识别客户端传过去的数据
set character_set_connection = gbk; // 更好的帮助客户端与服务器端之间惊醒字符集转换
set character_set_results = gbk; // 告诉客户端服务器返回的数据
