// patch.
Dataset patch = new Dataset
{
    FriendlyName = "Patched dataset"
};
BigQueryDataset updated = dataset.Patch(patch, matchETag: true);

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

Update(Dataset, UpdateDatasetOptions)

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

Returns
Type	Description
BigQueryDataset	The updated dataset.

Remarks

This method delegates to UpdateDataset(DatasetReference, Dataset, UpdateDatasetOptions). A simple way of updating the dataset 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 dataset 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 dataset. 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 dataset.

Example

BigQueryClient client = BigQueryClient.Create(projectId);
BigQueryDataset dataset = client.GetDataset(datasetId);

// 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.
dataset.Resource.FriendlyName = "Updated dataset";
BigQueryDataset updated = dataset.Update();

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

UpdateAsync(Dataset, UpdateDatasetOptions, CancellationToken)

cancellationToken	CancellationToken The token to monitor for cancellation requests.

Returns
Type	Description
TaskBigQueryDataset	A task representing the asynchronous operation. When complete, the result is the updated dataset.

Remarks

This method delegates to UpdateDatasetAsync(DatasetReference, Dataset, UpdateDatasetOptions, CancellationToken). A simple way of updating the dataset 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 dataset as it was when fetched, but then modified locally".

schema	TableSchema The schema of the data. May be null if the table already exists, in which case the table schema will be fetched and used.
rows	IEnumerablestring The sequence of JSON strings to upload. Must not be null, and must not contain null elements.
options	UploadJsonOptions The options for the operation. May be null, in which case defaults will be supplied.

Returns
Type	Description
BigQueryJob	A data upload job.

Remarks

Each element of rows is converted into a single line of text by replacing carriage returns and line feeds with spaces. This is safe as they cannot exist within well-formed JSON keys or values, and simply means that the original JSON can be formatted however you choose.

Example

See BigQueryClient.UploadJson for an example using BigQueryClient.
