推薦答案
第 1 步，更改數(shù)據(jù)庫的默認(rèn)字符集:
Step 1, change your database's default charset:
ALTER DATABASE database_name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;
如果尚未創(chuàng)建數(shù)據(jù)庫，請使用正確的編碼創(chuàng)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，創(chuàng)建表時設(shè)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;
