TableReference(dataset_ref: DatasetReference, table_id: str)

TableReferences are pointers to tables.

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

Parameter
Name	Description
table_id	str The ID of the table

Properties

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.

Methods

from_api_repr

from_api_repr(resource: dict) -> google.cloud.bigquery.table.TableReference

Factory: construct a table reference given its API representation

Parameter
Name	Description
resource	Dict[str, object] Table reference representation returned from the API

Returns
Type	Description
google.cloud.bigquery.table.TableReference	Table reference parsed from resource.

from_string

from_string(
    table_id: str, default_project: typing.Optional[str] = None
) -> google.cloud.bigquery.table.TableReference

Construct a table reference from table ID string.

Parameters
Name	Description
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.

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

Returns
Type	Description
TableReference .. rubric:: Examples >>> TableReference.from_string('my-project.mydataset.mytable') TableRef...(DatasetRef...('my-project', 'mydataset'), 'mytable')	Table reference parsed from table_id.

to_api_repr

to_api_repr() -> dict

Construct the API resource representation of this table reference.

Returns
Type	Description
Dict[str, object]	Table reference represented as an API resource

to_bqstorage

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 xref_TableReadOptions to filter rows by partition. Use xref_TableModifiers to select a specific snapshot to read from.

Returns
Type	Description
str	A reference to this table in the BigQuery Storage API.
