LINQ to Jira Assets 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 Jira Assets Data Provider.

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

  4. Enter your data source connection information.

    Jira Assets supports connecting and authenticating via the APIToken.

    To generate an API token:

    1. Log in to your Atlassian account.
    2. Navigate to Security < Create and manage API Token < Create API Token.

    Atlassian generates and then displays the API token.

    After you have generated the API token, set these parameters:

    • AuthScheme: APIToken.
    • User: The login of the authenticating user.
    • APIToken: The API token you just generated.

    You are now ready to connect and authenticate to Jira Assets.

    Below is a typical connection string:

    User=MyUser;APIToken=myApiToken;Url=https://yoursitename.atlassian.net
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting JiraAssetsEntities 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 , update, delete, and insert commands. For example:

JiraAssetsEntities context = new JiraAssetsEntities(); var objectsQuery = from objects in context.Objects select objects; foreach (var result in objectsQuery) { 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.
