Update Many Documents in MongoDB: Function and Example

Function 'updateMany' is a function used to update many documents within a collection in a database. This function is commonly used in NoSQL databases like MongoDB.

Example of using 'updateMany' function in MongoDB:

db.collection('users').updateMany(
   { age: { $lt: 30 } }, // Filter criteria
   { $set: { status: 'Active' } } // Value to be updated
)

In the example above, we will update all documents in the 'users' collection that have an age less than 30 years. The documents will be updated by adding the 'status' field with the value 'Active'.
