Standard ADO.NET Access to Cosmos DB

The Cosmos DB ADO.NET Provider offers the most natural way to access Cosmos DB data from any .NET application. Simply use Cosmos DB Data Provider objects to connect and access data just as you would access any traditional database. You will be able to use the Cosmos DB 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 Cosmos DB 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 Cosmos DB Data Provider has the same ADO.NET architecture as the native .NET data providers for SQL Server and OLEDB, including: Cosmos DBConnection, Cosmos DBCommand, Cosmos DBDataAdapter, Cosmos DBDataReader, Cosmos DBDataSource, Cosmos DBParameter, etc. Because of this you can now access Cosmos DB data in an easy, familiar way.

For example:

using (Cosmos DBConnection conn = new Cosmos DBConnection("...")) {
	string select = "SELECT * FROM DocumentDB";
	Cosmos DBCommand cmd = new Cosmos DBCommand(select, conn);
	Cosmos DBDataAdapter adapter = new Cosmos DBDataAdapter(cmd);
	using (adapter) {
		DataTable table = new DataTable();
		adapter.Fill(table);		
		...
	}
}

More Than Read-Only: Full Update/CRUD Support

Cosmos DB 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 Cosmos DB Data Provider as easily as interacting with a database table.

using (Cosmos DBConnection connection = new Cosmos DBConnection(connectionString)) {
	Cosmos DBDataAdapter dataAdapter = new Cosmos DBDataAdapter(
	"SELECT Id, Where FROM DocumentDB", connection);
  
	dataAdapter.UpdateCommand = new Cosmos DBCommand(
		"UPDATE DocumentDB SET Where = @Where " +
		"WHERE Id = @ID", connection);

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

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

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

	dataAdapter.Update(DocumentDBTable);
}
