You can delete all documents in a MongoDB collection using the "Delete" feature in MongoDB Compass. Here's how:
- Open MongoDB Compass: Launch the MongoDB Compass application.
- Select the Database and Collection: Navigate to the database and collection you want to clear.
- Click the "Delete" Button: Locate the "Delete" button on the collection's toolbar, usually represented by a trash can icon.
- Confirm the Deletion: A confirmation dialog will appear. Review the message and confirm the deletion by clicking the "Delete" button.
Important Considerations:
- Data Loss: Deleting all documents is irreversible. Make sure you have a backup or are comfortable losing the data before proceeding.
- Alternative Methods: You can also use the MongoDB shell or other tools to delete documents.
Example:
Let's say you have a collection named "users" in a database called "mydatabase." To delete all documents in the "users" collection, follow these steps:
- Open MongoDB Compass.
- Navigate to the "mydatabase" database and select the "users" collection.
- Click the "Delete" button on the collection's toolbar.
- Confirm the deletion in the dialog box.
Remember: This action will permanently delete all documents in the "users" collection.
