AccessEntry

AccessEntry(role:typing.Optional[str]=None,entity_type:typing.Optional[str]=None,entity_id:typing.Optional[typing.Union[typing.Dict[str,typing.Any],str]]=None,)

Represents grant of an access role to an entity.

An entry must have exactly one of the allowedxref_EntityTypes. If anything butview,routine,ordataset are set, arole is also required.role is omitted forview,routine,dataset, because they are always read-only.

Seehttps://cloud.google.com/bigquery/docs/reference/rest/v2/datasets.

Parameters
Name	Description
`role`	`typing.Optional[str]` Role granted to the entity. The following string values are supported:`'READER'`,`'WRITER'`,`'OWNER'`. It may also be :data:`None` if the`entity_type` is`view`,`routine`, or`dataset`.
`entity_type`	`typing.Optional[str]` Type of entity being granted the role. SeeEntityTypes for supported types.
`entity_id`	`typing.Union[typing.Dict[str, typing.Any], str, NoneType]` If the`entity_type` is not 'view', 'routine', or 'dataset', the`entity_id` is the`str` ID of the entity being granted the role. If the`entity_type` is 'view' or 'routine', the`entity_id` is a`dict` representing the view or routine from a different dataset to grant access to in the following format for views:: { 'projectId': string, 'datasetId': string, 'tableId': string } For routines:: { 'projectId': string, 'datasetId': string, 'routineId': string } If the`entity_type` is 'dataset', the`entity_id` is a`dict` that includes a 'dataset' field with a`dict` representing the dataset and a 'target_types' field with a`str` value of the dataset's resource type:: { 'dataset': { 'projectId': string, 'datasetId': string, }, 'target_types: 'VIEWS' }

Exceptions
Type	Description
`ValueError`	If a`view`,`routine`, or`dataset` has`role` set, or a non`view`, non`routine`, and non`dataset` does not have a`role` set. .. rubric:: Examples >>> entry = AccessEntry('OWNER', 'userByEmail', 'user@example.com') >>> view = { ... 'projectId': 'my-project', ... 'datasetId': 'my_dataset', ... 'tableId': 'my_table' ... } >>> entry = AccessEntry(None, 'view', view)

Dataset

Dataset(dataset_ref)

Datasets are containers for tables.

Seehttps://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`.`.

DatasetListItem

DatasetListItem(resource)

A read-only dataset resource from a list operation.

For performance reasons, the BigQuery API only includes some of thedataset properties when listing datasets. Notably,xref_access_entries is missing.

For a full list of the properties that the BigQuery API returns, see theREST documentation for datasets.list<https://cloud.google.com/bigquery/docs/reference/rest/v2/datasets/list>_.

Parameter
Name	Description
`resource`	`Dict[str, str]` A dataset-like resource object from a dataset list response. A`datasetReference` property is required.

Exceptions
Type	Description
`ValueError`	If`datasetReference` or one of its required members is missing from`resource`.

DatasetReference

DatasetReference(project:str,dataset_id:str)

DatasetReferences are pointers to datasets.

Seehttps://cloud.google.com/bigquery/docs/reference/rest/v2/datasets#datasetreference

Parameters
Name	Description
`project`	`str` The ID of the project
`dataset_id`	`str` The ID of the dataset

Exceptions
Type	Description
`ValueError`	If either argument is not of type`str`.
