Standard ADO.NET Access to CosmosDB

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: CosmosDBConnection, CosmosDBCommand, CosmosDBDataAdapter, CosmosDBDataReader, CosmosDBDataSource, CosmosDBParameter, etc. Because of this you can now access Cosmos DB data in an easy, familiar way.

For example:

using (CosmosDBConnection conn = new CosmosDBConnection("...")) {
	string select = "SELECT * FROM DocumentDB";
	CosmosDBCommand cmd = new CosmosDBCommand(select, conn);
	CosmosDBDataAdapter adapter = new CosmosDBDataAdapter(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 (CosmosDBConnection connection = new CosmosDBConnection(connectionString)) {
	CosmosDBDataAdapter dataAdapter = new CosmosDBDataAdapter(
	"SELECT Id, Where FROM DocumentDB", connection);
  
	dataAdapter.UpdateCommand = new CosmosDBCommand(
		"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);
}
