Collections

Copied!
( [database] )

Description

The Collections function, when executed with Paginate, returns an Array of References for all collections in the specified child database. If a child database is not specified, the returned collection references all belong to the current database.

When a child database is specified, an admin key must be used to call Collections (server or client keys, or ABAC tokens, cannot be used to access a child database).

Parameters
