google.cloud.bigquery.table.TableReference

class google.cloud.bigquery.table.TableReference(dataset_ref: DatasetReference, table_id: str)

TableReferences are pointers to tables.

See https://cloud.google.com/bigquery/docs/reference/rest/v2/tables#tablereference

Parameters

• dataset_ref – A pointer to the dataset

• table_id – The ID of the table

__init__(dataset_ref: DatasetReference, table_id: str)

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(dataset_ref, table_id)	Initialize self.
from_api_repr(resource)	Factory: construct a table reference given its API representation
from_string(table_id[, default_project])	Construct a table reference from table ID string.
to_api_repr()	Construct the API resource representation of this table reference.
to_bqstorage()	Construct a BigQuery Storage API representation of this table.

Attributes

dataset_id	ID of dataset containing the table.
path	URL path for the table’s APIs.
project	Project bound to the table.
table_id	The table ID.

property dataset_id: str

ID of dataset containing the table.

classmethod from_api_repr(resource: dict) → google.cloud.bigquery.table.TableReference

Factory: construct a table reference given its API representation

Parameters

resource (Dict[str, object]) – Table reference representation returned from the API

Returns

Table reference parsed from resource.

Return type

google.cloud.bigquery.table.TableReference

classmethod from_string(table_id: str, default_project: Optional[str] = None) → google.cloud.bigquery.table.TableReference

Construct a table reference from table ID string.

Parameters

• table_id (str) – A table ID in standard SQL format. If default_project is not specified, this must included a project ID, dataset ID, and table ID, each separated by ..

• default_project (Optional[str]) – The project ID to use when table_id does not include a project ID.

Returns

Table reference parsed from table_id.

Return type

TableReference

Examples

>>> TableReference.from_string('my-project.mydataset.mytable')
TableRef...(DatasetRef...('my-project', 'mydataset'), 'mytable')

Raises

ValueError – If table_id is not a fully-qualified table ID in standard SQL format.

property path: str

URL path for the table’s APIs.

property project: str

Project bound to the table.

property table_id: str

The table ID.

to_api_repr() → dict

Construct the API resource representation of this table reference.

Returns

Table reference represented as an API resource

Return type

Dict[str, object]

to_bqstorage() → str

Construct a BigQuery Storage API representation of this table.

Install the google-cloud-bigquery-storage package to use this feature.

If the table_id contains a partition identifier (e.g. my_table$201812) or a snapshot identifier (e.g. mytable@1234567890), it is ignored. Use google.cloud.bigquery_storage.types.ReadSession.TableReadOptions to filter rows by partition. Use google.cloud.bigquery_storage.types.ReadSession.TableModifiers to select a specific snapshot to read from.

Returns

A reference to this table in the BigQuery Storage API.

Return type

str
