LINQ to Oracle Sales 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 Oracle Sales Data Provider.

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

  4. Enter your data source connection information.

    Oracle Sales uses Basic authentication over SSL; after setting the following connection properties, you are ready to connect:

    • Username: Set this to the user name that you use to log into your Oracle Cloud service.
    • Password: Set this to your password.
    • HostURL: Set this to the Web address (URL) of your Oracle Cloud service.

    Below is a typical connection string:

    HostURL=https://my.host.oraclecloud.com; Username=abc123; Password=abcdef;
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting OracleSalesCloudEntities 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:

OracleSalesCloudEntities context = new OracleSalesCloudEntities(); var opportunitiesQuery = from opportunities in context.Opportunities select opportunities; foreach (var result in opportunitiesQuery) { Console.WriteLine("{0} {1} ", result.Id, result.OptyId); }

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