Standard ADO.NET Access to BigQuery

The Google BigQuery ADO.NET Provider offers the most natural way to access BigQuery data from any .NET application. Simply use Google BigQuery Data Provider objects to connect and access data just as you would access any traditional database. You will be able to use the Google BigQuery Data Provider through Visual Studio Server Explorer, in code through familiar classes, and in data controls like DataGridView, GridView, DataSet, etc.

The CData ADO.NET Provider for Google BigQuery hides the complexity of accessing data and provides additional powerful security features, smart caching, batching, socket management, and more.

Working with DataAdapters, DataSets, DataTables, etc.

The Google BigQuery Data Provider has the same ADO.NET architecture as the native .NET data providers for SQL Server and OLEDB, including: BigQueryConnection, BigQueryCommand, BigQueryDataAdapter, BigQueryDataReader, BigQueryDataSource, BigQueryParameter, etc. Because of this you can now access BigQuery data in an easy, familiar way.

For example:

using (BigQueryConnection conn = new BigQueryConnection("...")) {
	string select = "SELECT * FROM Dataset";
	BigQueryCommand cmd = new BigQueryCommand(select, conn);
	BigQueryDataAdapter adapter = new BigQueryDataAdapter(cmd);
	using (adapter) {
		DataTable table = new DataTable();
		adapter.Fill(table);		
		...
	}
}

More Than Read-Only: Full Update/CRUD Support

Google BigQuery Data Provider goes beyond read-only functionality to deliver full support for Create, Read, Update, and Delete operations (CRUD). Your end-users can interact with the data presented by the Google BigQuery Data Provider as easily as interacting with a database table.

using (BigQueryConnection connection = new BigQueryConnection(connectionString)) {
	BigQueryDataAdapter dataAdapter = new BigQueryDataAdapter(
	"SELECT Id, Where FROM Dataset", connection);
  
	dataAdapter.UpdateCommand = new BigQueryCommand(
		"UPDATE Dataset SET Where = @Where " +
		"WHERE Id = @ID", connection);

	dataAdapter.UpdateCommand.Parameters.AddWithValue("@Where", "Where");
	dataAdapter.UpdateCommand.Parameters.AddWithValue("@Id", "80000173-1387137645");

	DataTable DatasetTable = new DataTable();
	dataAdapter.Fill(DatasetTable);

	DataRow firstrow = DatasetTable.Rows[0];
	firstrow["Where"] = "New Location";

	dataAdapter.Update(DatasetTable);
}
