LINQ to NetSuite 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 NetSuite Data Provider.

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

  4. Enter your data source connection information.

    The User and Password properties, under the Authentication section, must be set to valid NetSuite user credentials. In addition, the AccountId must be set to the ID of a company account that can be used by the specified User. The RoleId can be optionally specified to log in the user with limited permissions.

    See the "Getting Started" chapter of the help documentation for more information on connecting to NetSuite.

    Below is a typical connection string:

    Account Id=XABC123456;Password=password;User=user;Role Id=3;Version=2013_1;
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting NetSuiteEntities 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:

NetSuiteEntities context = new NetSuiteEntities(); var salesorderQuery = from salesorder in context.SalesOrder select salesorder; foreach (var result in salesorderQuery) { Console.WriteLine("{0} {1} ", result.InternalId, result.CustomerName); }

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