ERROR 1366 (HY000): Incorrect string value: ‘\xE8\xB5\xB5\xE9\x9B\xB7‘ for column ‘s_ name‘ at row 1

mysql An error caused by a character set that does not meet the requirements

One of the reasons ： The character set is not specified when creating the table , Used after creating fields alter table Student default charset=utf8; Changed the character set to utf8; But it doesn't work for the created fields ;

 use show create table table_name\G;
 View table creation 
mysql> show create table Student\G;
*************************** 1. row ***************************
       Table: Student
Create Table: CREATE TABLE `Student` (
  `s_id` int(11) NOT NULL AUTO_INCREMENT,
  `s_name` varchar(10) CHARACTER SET latin1 DEFAULT NULL,
  `s_birth` varchar(10) CHARACTER SET latin1 DEFAULT NULL,
  `s_sex` enum(' male ',' Woman ') NOT NULL DEFAULT ' male ',
  PRIMARY KEY (`s_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

It is found that the character set of the table is different from that of the field
Modify the character set of the field ：

alter table Student modify s_name varchar(10) character set uft8;
