CData ADO.NET Provider for Google BigQuery 2019

CData ADO.NET Provider for Google BigQuery 2019 - Build 19.0.7354


The CData ADO.NET Provider for Google BigQuery 2019 offers the most natural way to access Google BigQuery data from .NET applications. The provider wraps the complexity of accessing Google BigQuery data in an easy-to-integrate, fully managed ADO.NET Data Provider. .NET applications can then access Google BigQuery as a traditional database through the provider.

The provider hides the complexity of accessing data and provides additional powerful security features, smart caching, batching, socket management, and more.

Key Features

  • DataBind to Google BigQuery using Visual Studio wizards.
  • Real-time access to Google BigQuery.
  • Comprehensive support for create, read, update, and delete (CRUD) operations.

Getting Started

See Getting Started for A-Z guides on authenticating and connecting to Google BigQuery data. See the Google BigQuery integration guides for information on connecting from other applications.


The provider has the same ADO.NET architecture as the native .NET data providers for SQL Server and OLEDB. Code with familiar classes such as GoogleBigQueryConnection, GoogleBigQueryCommand, GoogleBigQueryDataAdapter, GoogleBigQueryDataReader, GoogleBigQueryDataSource, GoogleBigQueryParameter, and so on. See Using ADO.NET for guides relating to these and other ADO.NET features such as batch processing, connection pooling, and calling stored procedures.

Entity Framework

You can leverage Entity Framework to quickly and easily model database resources using .NET objects. In Using ADO.NET (Entity Framework), you can find instructions related to EF6 setup and installation, as well as the creation of both model-first and code-first data models.

Entity Framework Core

Entity Framework Core provides a streamlined, cross-platform solution for modelling database resources as .NET objects. Using ADO.NET (Entity Framework Core) covers how to surface Google BigQuery data using EF Core console and ASP.NET applications. Additionally, you can find instructions for automatically building data models from data source metadata using reverse engineering (scaffolding).


LINQ queries allow you to query and modify data using simple, strongly typed expressions. For instructions regarding the construction and usage of LINQ queries, see Using ADO.NET (LINQ).


You can use the provider to enable real-time connectivity to Google BigQuery within your SSRS reports. Using ADO.NET (SSRS) details provider deploy, the creation of shared and embedded data sources and datasets, and the publishing of SSRS reports.


The provider supports the creation of strongly typed DbProviderFactory and DBConnection objects in order to facilitate connecting to Google BigQuery with generic code. Using ADO.NET (DbProviderFactory) describes how to get connected as well as create, configure, and execute DbCommands.

Schema Discovery

See Schema Discovery to use standard ADO.NET schema collections to discover schema information and other metadata. Query the System Tables to access additional metadata, such as data source capabilities.

SQL Compliance

See SQL Compliance for a syntax reference and code examples outlining the supported SQL.

Caching Data

See Caching Data to configure replication and caching for a range of scenarios common to remote data access. Configurations include:

  • Autocache: Automatically cache data to a lightweight database. Save data for later offline use or enable fast reporting from the cache.
  • Replication: Copy data to local and cloud data stores such as Oracle, SQL Server, Google Cloud SQL, and so on. The replication commands allow for intelligent incremental updates to cached data.
  • No caching: Work with remote data only. No local cache file is created.

Data Model

See Data Model for information on the available database objects and how to use SQL to work with Google BigQuery APIs. This section provides more detailed information on querying specific Google BigQuery entities.

Connection String Options

The Connection properties describe the various options that can be used to establish a connection.
