Google Spanner ADO.NET Provider

Standard ADO.NET Access to GoogleSpanner

The Google Spanner ADO.NET Provider offers the most natural way to access Google Spanner data from any .NET application. Simply use Spanner Data Provider objects to connect and access data just as you would access any traditional database. You will be able to use the Spanner 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 Spanner 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 Spanner Data Provider has the same ADO.NET architecture as the native .NET data providers for SQL Server and OLEDB, including: GoogleSpannerConnection, GoogleSpannerCommand, GoogleSpannerDataAdapter, GoogleSpannerDataReader, GoogleSpannerDataSource, GoogleSpannerParameter, etc. Because of this you can now access Google Spanner data in an easy, familiar way.

For example:

using (GoogleSpannerConnection conn = new GoogleSpannerConnection("...")) {
	string select = "SELECT * FROM NewSQLDB";
	GoogleSpannerCommand cmd = new GoogleSpannerCommand(select, conn);
	GoogleSpannerDataAdapter adapter = new GoogleSpannerDataAdapter(cmd);
	using (adapter) {
		DataTable table = new DataTable();
		adapter.Fill(table);		
		...
	}
}

More Than Read-Only: Full Update/CRUD Support

Spanner 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 Spanner Data Provider as easily as interacting with a database table.

using (GoogleSpannerConnection connection = new GoogleSpannerConnection(connectionString)) {
	GoogleSpannerDataAdapter dataAdapter = new GoogleSpannerDataAdapter(
	"SELECT Id, Where FROM NewSQLDB", connection);
  
	dataAdapter.UpdateCommand = new GoogleSpannerCommand(
		"UPDATE NewSQLDB SET Where = @Where " +
		"WHERE Id = @ID", connection);

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

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

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

	dataAdapter.Update(NewSQLDBTable);
}
