Inserting Integers in MongoDB: Example and Syntax Guide

Inserting Integer Fields in MongoDB

In MongoDB, you can store various data types, including integers, in a document. To insert an integer, you specify the integer value in the document when you use the insertOne() or insertMany() method.

Syntax:

db.collection.insertOne(
   { "fieldName": integerValue }
)

Explanation:

• db.collection: Replace collection with the target MongoDB collection's name.
• insertOne(): Used to insert a single document with fields containing the data, including integers.

Example:

The following example inserts a document with an integer field called age into a collection called users.

Code:

// Connect to the "users" collection and insert a document with an integer value
db.users.insertOne(
   { "name": " Arjuna Qing", "age": 30 }  // Insert "age" field as an integer value of 30
)

Explanation:

• db.users.insertOne:
• insertOne() inserts a single document into the users collection. This method will add one document to the database.
• { "name": " Arjuna Qing", "age": 30 }:
• The document has two fields: "name" with a string value, and "age" with an integer value. Here, age: 30 is the integer value being inserted. In MongoDB, numbers without decimal points are stored as Int32 by default if they are within the 32-bit integer range.

By using the correct syntax, MongoDB will store the field as an integer, which is useful for numerical operations like sorting, comparisons, and aggregations.
