MongoDB DELETING DOCUMENTS


🗑️ MongoDB: Deleting Documents

MongoDB provides methods to delete documents from collections based on filters. The most common methods are deleteOne() and deleteMany().

🔹 deleteOne()

Deletes the first document that matches the given filter.

db.users.deleteOne({ name: "John" })
  

🔹 deleteMany()

Deletes all documents that match the given filter.

db.users.deleteMany({ status: "inactive" })
  

🔹 Delete All Documents (⚠️ Use Carefully)

This will delete every document in a collection.

db.users.deleteMany({})
  
Warning: Deleting documents is permanent. Always double-check your filter criteria before executing a delete operation.
