$gt

The $gt operator in Amazon DocumentDB is used to select documents where the value of the specified field is greater than the specified value. This operator is useful for filtering and querying data based on numerical comparisons.

Parameters

Example (MongoDB Shell)

The following example demonstrates how to use the $gt operator to find all documents where the age field is greater than 30.

Create sample documents

db.users.insertMany([
  { name: "John", age: 25 },
  { name: "Jane", age: 32 },
  { name: "Bob", age: 45 },
  { name: "Alice", age: 28 }
]);

Query example

db.users.find({ age: { $gt: 30 } });

Output

{ "_id" : ObjectId("6249e5c22a5d39884a0a0001"), "name" : "Jane", "age" : 32 },
{ "_id" : ObjectId("6249e5c22a5d39884a0a0002"), "name" : "Bob", "age" : 45 }

  await client.close();
}

findUsersOlderThan30();

Python

from pymongo import MongoClient

def find_users_older_than_30():
    client = MongoClient('mongodb://<username>:<password>@<cluster-endpoint>:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false')
    db = client.test
    users = list(db.users.find({ 'age': { '$gt': 30 } }))
    print(users)
    client.close()
