$gte

The Greater Than or Equal To Operator ($gte) in MongoDB is an essential comparison operator. It compares two values and returns true if the first value is greater than or equal to the second value. It is highly useful for filtering documents based on specific criteria in your queries.

Syntax

The syntax for using the $gte operator is:

{
  field: {
    $gte: value;
  }
}

Where field is the name of the field being compared, and value is the comparison value.

Example

Let's explore an example using the $gte operator. Assume we have a collection products with the following documents:

[
  { _id: 1, product: 'A', price: 10 },
  { _id: 2, product: 'B', price: 20 },
  { _id: 3, product: 'C', price: 30 },
  { _id: 4, product: 'D', price: 40 },
  { _id: 5, product: 'E', price: 50 },
];

To find all documents where price is greater than or equal to 20, you can use the following query:

db.products.find({ price: { $gte: 20 } });

The output will be:

[
  { _id: 2, product: 'B', price: 20 },
  { _id: 3, product: 'C', price: 30 },
  { _id: 4, product: 'D', price: 40 },
  { _id: 5, product: 'E', price: 50 },
];

As we can see, the $gte operator successfully filtered the documents based on the specified criteria. This operator is extremely helpful when you need to narrow down your search or filter documents depending on certain conditions, making it a valuable addition to the toolbox of any MongoDB developer.
