db.getCollectionNames() (mongosh method)

Definition

db.getCollectionNames()

Returns an array containing the names of all collections and views in the current database, or if running with access control, the names of the collections according to user's privilege. For details, see Required Access.

Compatibility

This method is available in deployments hosted in the following environments:

• MongoDB Atlas: The fully managed service for MongoDB deployments in the cloud

• MongoDB Enterprise: The subscription-based, self-managed version of MongoDB
• MongoDB Community: The source-available, free-to-use, and self-managed version of MongoDB

Required Access

The db.getCollectionNames() is equivalent to:

db.runCommand(
   {
       listCollections: 1.0,
       authorizedCollections: true,
       nameOnly: true
   }
)

• For users with the required access (privileges that grant listCollections action on the database), the method lists the names of all collections for the database.
• For users without the required access, the method lists only the collections for which the users has privileges. For example, if a user has find on a specific collection in a database, the method would return just that collection.

Behavior

Example

The following returns the names of all collections in the records database:

use records
db.getCollectionNames()

The method returns the names of the collections in an array:

[ "employees", "products", "mylogs", "system.indexes" ]
