Google BigQuery v2 API - Class BigQueryTable (3.9.0)

public sealed class BigQueryTable : IFormattable

Reference documentation and code samples for the Google BigQuery v2 API class BigQueryTable.

A table within a BigQuery dataset.

Inheritance

object > BigQueryTable

Implements

IFormattable

Inherited Members

object.GetHashCode()

object.GetType()

Namespace

Google.Cloud.BigQuery.V2

Assembly

Google.Cloud.BigQuery.V2.dll

Remarks

This class wraps the underlying REST API resource and retains a reference to the original client, allowing for simpler table-oriented operations.

Constructors

BigQueryTable(BigQueryClient, Table)

public BigQueryTable(BigQueryClient client, Table resource)

Constructs a new table.

Parameters
Name	Description
`client`	`BigQueryClient` The client to use for operations on the table. Must not be null.
`resource`	`Table` The REST-ful resource representing the table. Must not be null.

Remarks

This is public to allow tests to construct instances for production code to consume; production code should not normally construct instances itself.

Properties

FullyQualifiedId

public string FullyQualifiedId { get; }

The fully-qualified identifier for the table in a string form of project.dataset.table.

Property Value
Type	Description
`string`

Reference

public TableReference Reference { get; }

The fully-qualified identifier for the table, as an object which can be used for other operations within this API.

Property Value
Type	Description
`TableReference`

Remarks

The properties within the reference can be used to determine the project ID, dataset ID and table ID components.

Resource

public Table Resource { get; }

The underlying REST-ful resource for the table.

Property Value
Type	Description
`Table`

Remarks

The data within the resource may be incomplete, depending on how it was obtained. (ListTables operations return less data than GetTable operations.)

Schema

public TableSchema Schema { get; }

The schema of this table, if known. Schemas are not retrieved when listing the tables within a dataset, so the value of this property can be null.

Property Value
Type	Description
`TableSchema`

Methods

CreateCopyJob(TableReference, CreateCopyJobOptions)

public BigQueryJob CreateCopyJob(TableReference destination, CreateCopyJobOptions options = null)

Update(Table, UpdateTableOptions)

public BigQueryTable Update(Table resource = null, UpdateTableOptions options = null)

Updates this table to match the specified resource.

Parameters
Name	Description
`resource`	`Table` The resource to update with. If null, the Resource property is used.
`options`	`UpdateTableOptions` The options for the operation. May be null, in which case defaults will be supplied.

Returns
Type	Description
`BigQueryTable`	The updated table.

Remarks

This method delegates to UpdateTable(TableReference, Table, UpdateTableOptions). A simple way of updating the table is to modify Resource and then call this method with no arguments. This is convenient, but it's important to understand that modifying Resource in this way leaves this object in an unusual state - it represents "the table as it was when fetched, but then modified locally". For example, the etag will be the original etag, rather than the one associated with the updated table. To avoid this causing confusion, we recommend only taking this approach if the object will not be used afterwards. Use the value returned by this method as the new, self-consistent representation of the table.

Example

BigQueryClient client = BigQueryClient.Create(projectId);
BigQueryTable table = client.GetTable(datasetId, tableId);

// This example modifies the in-memory resource in the BigQueryDataset,
// and then applies that change in the server. Alternatively, pass a Dataset
// into the Update method.
table.Resource.FriendlyName = "Updated table";
BigQueryTable updated = table.Update();

Console.WriteLine($"Updated table friendly name: {updated.Resource.FriendlyName}");

UpdateAsync(Table, UpdateTableOptions, CancellationToken)

Parameters
Name	Description
`resource`	`Table` The resource to update with. If null, the Resource property is used.
`options`	`UpdateTableOptions` The options for the operation. May be null, in which case defaults will be supplied.
`cancellationToken`	`CancellationToken` The token to monitor for cancellation requests.

Returns
Type	Description
`TaskBigQueryTable`	A task representing the asynchronous operation. When complete, the result is the updated table.

Remarks

This method delegates to UpdateTableAsync(TableReference, Table, UpdateTableOptions, CancellationToken). A simple way of updating the table is to modify Resource and then call this method with no arguments. This is convenient, but it's important to understand that modifying Resource in this way leaves this object in an unusual state - it represents "the table as it was when fetched, but then modified locally". For example, the etag will be the original etag, rather than the one associated with the updated table. To avoid this causing confusion, we recommend only taking this approach if the object will not be used afterwards. Use the value returned by this method as the new, self-consistent representation of the table.

Example
