刪除表的命令

drop table 表名;

如果有200張表，執行200次，想想就不想動手了。

下面提供一個使用information_schema庫的方案：

SELECT CONCAT('drop table ',table_name,';') FROM information_schema.`TABLES` WHERE table_schema='資料庫名';

例子

mysql> SELECT CONCAT('drop table ',table_name,';') FROM information_schema.`TABLES` WHERE table_schema=
 
'django_demo';
+----------------------------------------+
| CONCAT('drop table ',table_name,';')   |
+----------------------------------------+
| drop table auth_group;                 |
| drop table auth_group_permissions;     |
| drop table auth_permission;            |
| drop table auth_user;                  |
 

| drop table auth_user_groups;           |
| drop table auth_user_user_permissions; |
| drop table django_admin_log;           |
| drop table django_content_type;        |
| drop table django_migrations;          |
| drop table django_session;             |
| drop table tb_books;                   |
 

+----------------------------------------+
11 rows in set (0.00 sec)

去掉|

a = '''
| drop table auth_group;                 |
| drop table auth_group_permissions;     |
| drop table auth_permission;            |
| drop table auth_user;                  |
| drop table auth_user_groups;           |
| drop table auth_user_user_permissions; |
| drop table django_admin_log;           |
| drop table django_content_type;        |
| drop table django_migrations;          |
| drop table django_session;             |
| drop table tb_books;   '''

print(a.replace('|', ''))

複製到資料庫執行兩次(因為可能表有關聯)
