LINQ to NetSuite 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 NetSuite Data Provider.

This article demonstrates how to use LINQ to access NetSuite tables through the CData ADO.NET Data Provider for NetSuite. 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 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.
