推荐答案

第 1 步，更改数据库的默认字符集:

Step 1, change your database's default charset:

ALTER DATABASE database_name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;

如果尚未创建数据库，请使用正确的编码创建它:

if the db is not created yet, create it with correct encodings:

CREATE DATABASE database_name DEFAULT CHARSET = utf8mb4 DEFAULT COLLATE = utf8mb4_unicode_ci;

第2步，创建表时设置字符集:

Step 2, set charset when creating table:

CREATE TABLE IF NOT EXISTS table_name ( ... ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE utf8mb4_unicode_ci;

或修改表格

ALTER TABLE table_name CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; ALTER TABLE table_name MODIFY field_name TEXT CHARSET utf8mb4;
