Mysql Incorrect string value: ‘\xF0\xA3\x8E\xB4’ for column ‘msg’ at row 1

MySQL version 5.7.2

Check the data and modify the character set utf8mb4

I simply think that modifying the character set of the field can be solved, and then continue to report errors

I’m really angry. I modified the character set of the real table, and then continue to report errors

No temper

Find a blog to continue authentication and find that they have to modify the MySQL configuration file

Then I modified the character set in my.ini file



Then restart mysql,

I tried it anxiously and found that it didn’t succeed,

A word is missing

SET NAMES utf8mb4

Then it succeeded.

Then I found that this statement was one-time. Awkward…

Honestly increase configuration

3. Modify the MySQL configuration file my.cnf (my.ini for Windows)

My.cnf is usually located in etc/MySQL/my.cnf. After finding it, please add the following contents in the following three parts:
default-character-set = utf8mb4
default-character-set = utf8mb4
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
init_ connect=’SET NAMES utf8mb4′

The cost of such modification is a little big. It’s too troublesome. Forget it. Although successful, it will not change.
