Class TableServiceClient (2.27.0)

This is an experimental RPC service definition for the BigQuery Table Service.

It should not be relied on for production use cases at this time.

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions

GetTable(google::cloud::bigquery::v2::GetTableRequest const &, Options)

Gets the specified table resource by table ID.

This method does not return the data in the table, it only returns the table resource, which describes the structure of this table.

Parameters
Name	Description
`request`	`google::cloud::bigquery::v2::GetTableRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.bigquery.v2.GetTableRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::bigquery::v2::Table >`	the result of the RPC. The response message type (google.cloud.bigquery.v2.Table) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

InsertTable(google::cloud::bigquery::v2::InsertTableRequest const &, Options)

Creates a new, empty table in the dataset.

Parameters
Name	Description
`request`	`google::cloud::bigquery::v2::InsertTableRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.bigquery.v2.InsertTableRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::bigquery::v2::Table >`	the result of the RPC. The response message type (google.cloud.bigquery.v2.Table) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

PatchTable(google::cloud::bigquery::v2::UpdateOrPatchTableRequest const &, Options)

Updates information in an existing table.

The update method replaces the entire table resource, whereas the patch method only replaces fields that are provided in the submitted table resource. This method supports RFC5789 patch semantics.

Parameters
Name	Description
`request`	`google::cloud::bigquery::v2::UpdateOrPatchTableRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.bigquery.v2.UpdateOrPatchTableRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::bigquery::v2::Table >`	the result of the RPC. The response message type (google.cloud.bigquery.v2.Table) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

UpdateTable(google::cloud::bigquery::v2::UpdateOrPatchTableRequest const &, Options)

Updates information in an existing table.

The update method replaces the entire Table resource, whereas the patch method only replaces fields that are provided in the submitted Table resource.

Parameters
Name	Description
`request`	`google::cloud::bigquery::v2::UpdateOrPatchTableRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.bigquery.v2.UpdateOrPatchTableRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::bigquery::v2::Table >`	the result of the RPC. The response message type (google.cloud.bigquery.v2.Table) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

DeleteTable(google::cloud::bigquery::v2::DeleteTableRequest const &, Options)

Deletes the table specified by tableId from the dataset.

If the table contains data, all the data will be deleted.

Parameters
Name	Description
`request`	`google::cloud::bigquery::v2::DeleteTableRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.bigquery.v2.DeleteTableRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`Status`	a `Status` object. If the request failed, the status contains the details of the failure.

ListTables(google::cloud::bigquery::v2::ListTablesRequest, Options)

Lists all tables in the specified dataset.

Requires the READER dataset role.

Parameters
Name	Description
`request`	`google::cloud::bigquery::v2::ListTablesRequest` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.bigquery.v2.ListTablesRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

StreamRange< google::cloud::bigquery::v2::ListFormatTable >

a StreamRange to iterate of the results. See the documentation of this type for details. In brief, this class has begin() and end() member functions returning a iterator class meeting the input iterator requirements. The value type for this iterator is a StatusOr as the iteration may fail even after some values are retrieved successfully, for example, if there is a network disconnect. An empty set of results does not indicate an error, it indicates that there are no resources meeting the request criteria. On a successful iteration the StatusOr<T> contains elements of type google.cloud.bigquery.v2.ListFormatTable, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.
