Modifying the data encoding format for MySQL

Occurs when inserting data in MySQL

mysql> INSERT INTO user values ("1", "Li Hong", "23", "Jilin Changchun", "2");

ERROR 1366 (HY000): Incorrect string value: ' \xe6\x9d\x8e\xe7\xba\xa2 ' for column ' name ' at row 1

Because Chinese is inserted in this column, modify the encoding format of the table user

Use ALTER TABLE user default character set UTF8;

Create table user with show, query

mysql> ALTER TABLE user default character set UTF8;

Query OK, 0 rows affected (0.03 sec)

records:0 duplicates:0 warnings:0

Mysql> Show create table user;

' id ' int (one) DEFAULT NULL,

' Name ' char (+) CHARACTER SET latin1 DEFAULT NULL,

' Age ' int (one) DEFAULT NULL,

' Address ' char (+) CHARACTER SET latin1 DEFAULT NULL,

' Wage ' tinyint (4) DEFAULT NULL

) Engine=innodb DEFAULT Charset=utf8 |

1 row in Set (0.01 sec)

Found the Name column, and the address column is still latin1 encoded format

Modify the encoding format of two columns with the following two lines

ALTER TABLE user change name name char (+) Character set Utf8;alter table user change address address char (+) character s ET UTF8;

That's it.
