$gte - Amazon DocumentDB
Example (MongoDB Shell)Code examples

$gte

The $gte aggregation operator compares two values and returns true if the first value is greater than or equal to the second, otherwise returns false.

Parameters

  • expression1: The first value to compare.

  • expression2: The second value to compare.

Example (MongoDB Shell)

The following example demonstrates using the $gte operator to check if students passed an exam.

Create sample documents

db.students.insertMany([
  { _id: 1, name: "Alice", score: 85 },
  { _id: 2, name: "Bob", score: 60 },
  { _id: 3, name: "Charlie", score: 72 }
]);

Query example

db.students.aggregate([
  {
    $project: {
      name: 1,
      score: 1,
      passed: { $gte: ["$score", 70] }
    }
  }
]);

Output

[
  { _id: 1, name: 'Alice', score: 85, passed: true },
  { _id: 2, name: 'Bob', score: 60, passed: false },
  { _id: 3, name: 'Charlie', score: 72, passed: true }
]

  const collection = db.collection('students');

  const result = await collection.aggregate([

        name: 1,
        score: 1,
        passed: { $gte: ["$score", 70] }
      }
    }
  ]).toArray();

  console.log(result);
  await client.close();
