Working with SAP Data in LINQPad

Execute LINQ queries to SAP data in LINQPad.

The CData ADO.NET Provider for SAP enables you to use standard ADO.NET interfaces like LINQ and the Entity Framework to work with SAP data. This article shows how to connect from LINQPad and execute LINQ queries.

Create the Data Model

After downloading and installing the provider and LINQPad, create a new class library project in Visual Studio.

See the help documentation for a guide to setting up an EF 6 project to use the provider.

  1. Right-click your project and click Add -> New Item -> ADO.NET Entity Data Model. In the resulting dialog, select Code First from database. Click New Connection and specify the connection string options in the resulting wizard.

    You can connect to SAP systems using either librfc32.dll, librfc32u.dll, NetWeaver, or Web Services (SOAP). Set the ConnectionType connection property to CLASSIC (librfc32.dll), CLASSIC_UNICODE (librfc32u.dll), NETWEAVER, or SOAP.

    If you are using the SOAP interface, set the Client, RFCUrl, SystemNumber, User, and Password properties, under the Authentication section.

    Otherwise, set Host, User, Password, Client, and SystemNumber.

    Note: We do not distribute the librfc32.dll or other SAP assemblies. You must find them from your SAP installation and install them on your machine.

    For more information, see this guide on obtaining the connection properties needed to connect to any SAP system.

    Below is a typical connection string:

    Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;Location=C:\\mysapschemafolder;
  2. Select the desired tables and views and click Finish to create the data model.

  3. Build the project. The generated files can be used to create the SAP connection in LINQPad.

Connect to SAP Data in LINQPad

After you have obtained the required connection properties and created the data model assembly, follow the steps below to start using the data model in LINQPad.

  1. Open LINQPad and click Add Connection.

  2. Select the "Use a typed data context from your own assembly" option.

  3. Select Entity Framework DbContext.

  4. Click Browse next to the Path to Custom Assembly box and browse to your project folder. Browse to the .dll or .exe under the bin folder.

  5. Select the name of the DbContext.
  6. If you saved your connection string in App.Config, specify the path to the App.config.

You can now query SAP data through LINQPad. For examples of the supported LINQ queries, see the "LINQ and Entity Framework" chapter in the help documentation.
