DatabaseProxy Class

Reference

An interface to interact with a specific database.

This class should not be instantiated directly. Instead use the <xref:CosmosClient.get_database_client> method.

A database contains one or more containers, each of which can contain items, stored procedures, triggers, and user-defined functions.

A database can also have associated users, each of which is configured with a set of permissions for accessing certain containers, stored procedures, triggers, user-defined functions, or items.

An Azure Cosmos DB SQL API database has the following system-generated properties. These properties are read-only:

_rid: The resource ID.
_ts: When the resource was last updated. The value is a timestamp.
_self: The unique addressable URI for the resource.
_etag: The resource etag required for optimistic concurrency control.
_colls: The addressable path of the collections resource.
_users: The addressable path of the users resource.

DatabaseProxy

Constructor

DatabaseProxy(client_connection: CosmosClientConnection, id: str, properties: Dict[str, Any] | None = None)

Parameters

Name	Description
client_connection Required	<xref:ClientSession> Client from which this database was retrieved.
id Required	str ID (name) of the database.
properties	Default value: None

Variables

Name	Description
id	The ID (name) of the database.

Methods

create_container	Create a new container with the given ID (name). If a container with the given ID already exists, a CosmosResourceExistsError is raised.
create_container_if_not_exists	Create a container if it does not exist already. If the container already exists, the existing settings are returned. Note: it does not check or update the existing container settings or offer throughput if they differ from what was passed into the method.
create_user	Create a new user in the container. To update or replace an existing user, use the <xref:ContainerProxy.upsert_user> method.
delete_container	Delete a container.
delete_user	Delete the specified user from the container.
get_container_client	Get a ContainerProxy for a container with specified ID (name).
get_throughput	Get the ThroughputProperties object for this database. If no ThroughputProperties already exist for the database, an exception is raised.
get_user_client	Get a UserProxy for a user with specified ID.
list_containers	List the containers in the database.
list_users	List all the users in the container.
query_containers	List the properties for containers in the current database.
query_users	Return all users matching the given query.
read	Read the database properties.
read_offer	Get the ThroughputProperties object for this database. If no ThroughputProperties already exist for the database, an exception is raised.
replace_container	Reset the properties of the container. Property changes are persisted immediately. Any properties not specified will be reset to their default values.
replace_throughput	Replace the database-level throughput.
replace_user	Replaces the specified user if it exists in the container.
upsert_user	Insert or update the specified user. If the user already exists in the container, it is replaced. If the user does not already exist, it is inserted.
