How to: Execute a SpecificFinder Method on an Entity

SharePoint 2007

A SpecificFinder is a special method that given a key (unique ID) returns one entity instance. For example, for the Customer entity, the SpecificFinder method might be the following:

SELECT * FROM Customers where ID=1

This topic shows how to execute a SpecificFinder method on an entity registered in the Business Data Catalog.

Example

This example shows how to execute a SpecificFinder method on the Product entity in the AdventureWorks2000 sample.

Prerequisites

  • Ensure a Shared Service Provider is already created.

  • Replace the constant value EnterYourSSPNameHere in the code with the name of your Shared Resource Provider.

  • Ensure the LobSystem and entity names referenced in the example exist in the Business Data Catalog. Use valid names.

            IEntityInstance IE = prodEntity.FindSpecific(1, AdvWorksIns);
