LINQ to Oracle Sales Cloud Data

LINQ provides general-purpose query facilities in .NET Framework 3.0 and above and provides one easy way to programmatically access data through from CData ADO.NET Data Providers. This example uses LINQ to access information from the Oracle Sales Cloud Data Provider.

This article demonstrates how to use LINQ to access Oracle Sales Cloud tables through the CData ADO.NET Data Provider for Oracle Sales Cloud. To do this you will LINQ to Entity Framework, which is used to generate the connection and can be used with any CData ADO.NET Data Providers to access data via 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 Cloud Data Source".
  4. Enter your data source connection information.

    OracleSalesCloud 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.
