LINQ to Google Ads Data

This article illustrates using LINQ to access tables within the Google Ads via the CData ADO.NET Data Provider for Google Ads. To achieve this, we will use LINQ to Entity Framework, which facilitates the generation of connections and can be seamlessly employed with any CData ADO.NET Data Providers to access data through LINQ.

See the help documentation for a guide to setting up an EF 6 project to use the provider.

1. In a new project in Visual Studio, right-click on the project and choose to add a new item. Add an ADO.NET Entity Data Model.
2. Choose EF Designer from Database and click Next.
3. Add a new Data Connection, and change your data source type to "CData Google Ads Data Source".

4. Enter your data source connection information.

   Google uses the OAuth authentication standard. To access Google APIs on behalf on individual users, you can use the embedded credentials or you can register your own OAuth app.

   OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, register an application to obtain the OAuth JWT values.

   In addition to the OAuth values, specify the DeveloperToken and ClientCustomerId.

   See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

   Below is a typical connection string:

   DeveloperToken=MyDeveloperToken;ClientCustomerId=MyClientCustomerId;InitiateOAuth=GETANDREFRESH;

👁 Required connection properties for the data source. (QuickBooks is shown.)

5. If saving your entity connection to App.Config, set an entity name. In this example we are setting GoogleAdsEntities as our entity connection in App.Config.
6. Enter a model name and select any tables or views you would like to include in the model.

Using the entity you created, you can now perform select commands. For example:

GoogleAdsEntities context = new GoogleAdsEntities();

var campaignperformanceQuery = from campaignperformance in context.CampaignPerformance
 select campaignperformance;

foreach (var result in campaignperformanceQuery) {
 Console.WriteLine("{0} {1} ", result.Id, result.Device);
}

See "LINQ and Entity Framework" chapter in the help documentation for example queries of the supported LINQ.
