LINQ to Bugzilla Data


LINQ offers versatile querying capabilities within the .NET Framework (v3.0+), offering a straightforward method for programmatic data access through CData ADO.NET Data Providers. In this article, we demonstrate the use of LINQ to retrieve information from the Bugzilla Data Provider.

This article illustrates using LINQ to access tables within the Bugzilla via the CData ADO.NET Data Provider for Bugzilla. 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 Bugzilla Data Source".

  4. Enter your data source connection information.

    You can authenticate to your Bugzilla account using two parameters:

    • URL: The URL of your Bugzilla developer's page (the Home page).
    • ApiKey: API Keys can be generated from the Preferences -> API Keys section of your Bugzilla developer's page.

    Below is a typical connection string:

    Url=http://yourdomain/Bugzilla;APIKey=abc123;
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting BugzillaEntities 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:

BugzillaEntities context = new BugzillaEntities(); var bugsQuery = from bugs in context.Bugs select bugs; foreach (var result in bugsQuery) { Console.WriteLine("{0} {1} ", result.Id, result.Id); }

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