    Class Dataset (3.4.0) 

      Dataset 
 ( 
 dataset_ref 
 )

    Datasets are containers for tables.

    See https://cloud.google.com/bigquery/docs/reference/rest/v2/datasets#resource-dataset

    Parameter

    Name
    Description
    dataset_ref
    Union[ google.cloud.bigquery.dataset.DatasetReference , str]

    A pointer to a dataset. If dataset_ref is a string, it must include both the project ID and the dataset ID, separated by . .

    Inheritance

    builtins.object > Dataset

    Properties

    access_entries

    List[ google.cloud.bigquery.dataset.AccessEntry ]: Dataset's access entries.

    role augments the entity type and must be present unlessthe entity type is view or routine .

    Exceptions
    Type
    Description
    TypeError
    If 'value' is not a sequence
    ValueError
    If any item in the sequence is not an AccessEntry .

    created

    Union[datetime.datetime, None]: Datetime at which the dataset was created (:data: None until set from the server).

    dataset_id

    str: Dataset ID.

    default_encryption_configuration

    google.cloud.bigquery.encryption_configuration.EncryptionConfiguration : Custom encryption configuration for all tables in the dataset.

    Custom encryption configuration (e.g., Cloud KMS keys) or :data: None if using default encryption.

    See protecting data with Cloud KMS keys < https://cloud.google.com/bigquery/docs/customer-managed-encryption> ; _ in the BigQuery documentation.

    default_partition_expiration_ms

    Optional[int]: The default partition expiration for all partitioned tables in the dataset, in milliseconds.

    Once this property is set, all newly-created partitioned tables in the dataset will have an time_paritioning.expiration_ms property set to this value, and changing the value will only affect new tables, not existing ones. The storage in a partition will have an expiration time of its partition time plus this value.

    Setting this property overrides the use of default_table_expiration_ms for partitioned tables: only one of default_table_expiration_ms and default_partition_expiration_ms will be used for any new partitioned table. If you provide an explicit time_partitioning.expiration_ms when creating or updating a partitioned table, that value takes precedence over the default partition expiration time indicated by this property.

    default_table_expiration_ms

    Union[int, None]: Default expiration time for tables in the dataset (defaults to :data: None ).

    Exceptions
    Type
    Description
    ValueError
    For invalid value types.

    description

    Optional[str]: Description of the dataset as set by the user (defaults to :data: None ).

    Exceptions
    Type
    Description
    ValueError
    for invalid value types.

    etag

    Union[str, None]: ETag for the dataset resource (:data: None until set from the server).

    friendly_name

    Union[str, None]: Title of the dataset as set by the user (defaults to :data: None ).

    Exceptions
    Type
    Description
    ValueError
    for invalid value types.

    full_dataset_id

    Union[str, None]: ID for the dataset resource (:data: None until set from the server)

    In the format project_id:dataset_id .

    labels

    Dict[str, str]: Labels for the dataset.

    This method always returns a dict. To change a dataset's labels, modify the dict, then call xref_update_dataset. To delete a label, set its value to :data: None before updating.

    Exceptions
    Type
    Description
    ValueError
    for invalid value types.

    location

    Union[str, None]: Location in which the dataset is hosted as set by the user (defaults to :data: None ).

    Exceptions
    Type
    Description
    ValueError
    for invalid value types.

    modified

    Union[datetime.datetime, None]: Datetime at which the dataset was last modified (:data: None until set from the server).

    path

    str: URL path for the dataset based on project and dataset ID.

    project

    str: Project ID of the project bound to the dataset.

    reference

    google.cloud.bigquery.dataset.DatasetReference : A reference to this dataset.

    Union[str, None]: URL for the dataset resource (:data: None until set from the server).
