mongodb drop database

To drop a database in MongoDB, you can use the dropDatabase() method. Here are the steps to drop a database in MongoDB:

1. Open the MongoDB shell: Open a terminal or command prompt and run the mongo command to open the MongoDB shell.

2. Switch to the database you want to drop: Use the use command followed by the name of the database to switch to the database you want to drop. For example, to switch to a database named "mydb", run the following command:

use mydb

3. Drop the database: Run the dropDatabase() method to drop the database. For example, to drop the "mydb" database, run the following command:

db.dropDatabase()

4. Confirm the database has been dropped: MongoDB will return a message indicating that the database has been dropped. You can also check for the existence of the database by running the show dbs command.

Note that dropping a database will permanently delete all data stored in that database. Make sure to back up any important data before dropping a database.
