Definition¶

db.getCollectionNames()¶: Returns an array containing the names of all collections in the current database.

Considerations¶

Changed in version 3.0.0.

For MongoDB 3.0 deployments using the WiredTiger storage engine, if you run db.getCollectionNames() from a version of the mongo shell before 3.0 or a version of the driver prior to 3.0 compatible version, db.getCollectionNames() will return no data, even if there are existing collections. For more information, see WiredTiger and Driver Version Compatibility.

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" ]

← db.getCollectionInfos() db.getLastError() →
