删除mysql数据库中所有表

删除表的命令

drop table 表名;

如果有200张表，执行200次，想想就不想动手了。

下面提供一个使用information_schema库的方案：

SELECT CONCAT('drop table ',table_name,';') FROM information_schema.`TABLES` WHERE table_schema='数据库名';

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('|', ''))

复制到数据库执行两次(因为可能表有关联)
