Oracle HCM Cloud ADO.NET Provider

Rapidly create and deploy powerful .NET applications that integrate with Oracle HCM Cloud.

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 HCM Cloud Data Provider.

This article demonstrates how to use LINQ to access Oracle HCM Cloud tables through the CData ADO.NET Data Provider for Oracle HCM 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 HCM Cloud Data Source".
  4. Enter your data source connection information.

    Using Basic Authentication

    You must set the following to authenticate to Oracle HCM Cloud:

    • Url: The Url of your account.
    • User: The user of your account.
    • Password: The password of your account.

    Below is a typical connection string:

  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting OracleHCMEntities 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:

OracleHCMEntities context = new OracleHCMEntities(); var recruitingcesitesQuery = from recruitingcesites in context.RecruitingCESites select recruitingcesites; foreach (var result in recruitingcesitesQuery) { Console.WriteLine("{0} {1} ", result.Id, result.SiteId); }

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