在终端执行:

mongo // To go to shell

show databases // To show all existing databases.

use <DATA_BASE> // To switch to the wanted database.

db.dropDatabase() // To remove the current database.

打开另一个终端窗口，执行以下命令，

mongodb
use mydb
db.dropDatabase()

该操作的输出如下所示

MAC:FOLDER USER$ mongodb
> show databases
local      0.78125GB
mydb       0.23012GB
test       0.23012GB
> use mydb
switched to db mydb
>db.dropDatabase()
{ "dropped" : "mydb", "ok" : 1 }
>

请注意，mydb仍在使用中，因此此时插入任何输入都将重新初始化数据库。

我发现这很容易记住:

mongo //to start the mongodb shell

show dbs //to list existing databases

use <dbname> //the <dbname> is the database you'd like to drop

db //should show <dbname> just to be sure I'm working with the right database

db.dropDatabase() //will delete the database & return { "dropped" : "<dbname>", "ok" : 1 }

在终端执行:

mongo // To go to shell

show databases // To show all existing databases.

use <DATA_BASE> // To switch to the wanted database.

db.dropDatabase() // To remove the current database.

启动MongoDB

数据库删除命令为:

1. 首先选择要删除的数据库

use < database name >

2. 然后用这个。。

db.dropDatabase()

打开终端，输入:

mongo 

下面的命令应该显示列出的数据库:

show dbs 

/* the <dbname> is the database you'd like to drop */
use <dbname> 

/* the below command will delete the database */
db.dropDatabase()  

终端输出如下:

{
  "dropped": "<dbname>",
  "ok": 1
}
