MySQL是一個(gè)常用的關(guān)系型數(shù)據(jù)庫管理系統(tǒng),它支持多種字符集進(jìn)行數(shù)據(jù)的存儲(chǔ)和顯示。本文將介紹如何通過圖形工具修改MySQL字符集。
1. 打開MySQL圖形工具,連接需要修改字符集的數(shù)據(jù)庫。
$ mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
...
mysql>use mydb;
2. 打開表結(jié)構(gòu),選擇需要修改字符集的表。
mysql>show tables;
+-----------------------+
| Tables_in_mydb |
+-----------------------+
| users |
| orders |
+-----------------------+
2 rows in set (0.00 sec)
mysql>describe users;
+-------------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+--------------+------+-----+---------+-------+
| id | int(11) | NO | PRI | NULL | |
| name | varchar(100) | YES | | NULL | |
| email | varchar(100) | YES | | NULL | |
| password | varchar(100) | YES | | NULL | |
+-------------+--------------+------+-----+---------+-------+
4 rows in set (0.01 sec)
3. 打開字段結(jié)構(gòu),選擇需要修改字符集的字段。
mysql>alter table users modify name varchar(100) character set utf8mb4;
Query OK, 4 rows affected (0.05 sec)
Records: 4 Duplicates: 0 Warnings: 0
mysql>describe users;
+-------------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+--------------+------+-----+---------+-------+
| id | int(11) | NO | PRI | NULL | |
| name | varchar(100) | YES | | NULL | |
| email | varchar(100) | YES | | NULL | |
| password | varchar(100) | YES | | NULL | |
+-------------+--------------+------+-----+---------+-------+
4 rows in set (0.00 sec)
4. 修改字符集成功。
通過MySQL圖形工具修改字符集,可以方便地對(duì)MySQL數(shù)據(jù)庫中的數(shù)據(jù)進(jìn)行存儲(chǔ)和顯示,使得數(shù)據(jù)更加易讀易理解。
