语法

声明
<SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel:=True)> _
Public NotInheritable Class SqlSessionProvider
用法
Dim instance As SqlSessionProvider

[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel=true)] 
public sealed class SqlSessionProvider

备注

The SQLSessionProvider is a singleton that can be accessed through its Instance property.

示例

The Business Data Catalog is implemented as a Microsoft Office SharePoint Server 2007 shared service and is shared across a Shared Resource Provider. Therefore, before you can use the ApplicationRegistry object, you must reference the Shared Resource Provider associated with the Business Data Catalog.

The following code example shows how to set the default Shared Services Provider (SSP) in your local server farm for use with the Business Data Catalog, and how to display the names of the systems that are registered in the Business Data Catalog. Specifying the SSP is the first step in setting up a console application to work with the Business Data Catalog.

After you specify the Shared Resource Provider, you can use the ApplicationRegistry object to get the LobSystemInstance objects that are registered with the Business Data Catalog, as shown in the following example.

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.
