ALTER TABLE share_zodiacshare MODIFY COLUMN zodiac_chinese VARCHAR(6) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
查看三種MySQL字符集的方法
1. 查看MySQL數(shù)據(jù)庫(kù)服務(wù)器和數(shù)據(jù)庫(kù)MySQL字符集。
mysql> show variables like '%char%';
+--------------------------+-------------------------------------+------
| Variable_name | Value |......
+--------------------------+-------------------------------------+------
| character_set_client | utf8 |...... -- 客戶端字符集
| character_set_connection | utf8 |......
| character_set_database | utf8 |...... -- 數(shù)據(jù)庫(kù)字符集
| character_set_filesystem | binary |......
| character_set_results | utf8 |......
| character_set_server | utf8 |...... -- 服務(wù)器字符集
| character_set_system | utf8 |......
| character_sets_dir | D:\MySQL Server 5.0\share\charsets\ |......
+--------------------------+-------------------------------------+------
2. 查看MySQL數(shù)據(jù)表（table）的MySQL字符集图云。
mysql> show table status from sqlstudy_db like '%countries%';
+-----------+--------+---------+------------+------+-----------------+------
| Name | Engine | Version | Row_format | Rows | Collation |......
+-----------+--------+---------+------------+------+-----------------+------
| countries | InnoDB | 10 | Compact | 11 | utf8_general_ci |......
+-----------+--------+---------+------------+------+-----------------+------
3. 查看MySQL數(shù)據(jù)列（column）的MySQL字符集袍辞。
mysql> show full columns from countries;
+----------------------+-------------+-----------------+--------
| Field | Type | Collation | .......
+----------------------+-------------+-----------------+--------
| countries_id | int(11) | NULL | .......
| countries_name | varchar(64) | utf8_general_ci | .......
| countries_iso_code_2 | char(2) | utf8_general_ci | .......
| countries_iso_code_3 | char(3) | utf8_general_ci | .......
| address_format_id | int(11) | NULL | .......
