Property Value
Type: System.Data.IDbCommand
An IDbCommand object that contains a query or stored procedure.
Remarks
This command updates information from the scope metadata table, such as the synchronization knowledge and cleanup knowledge that Sync Framework requires. For more information about how scope is used, see "Creating Tracking Tables to Store Metadata" in How to: Provision a Server Database for Collaborative Synchronization (Non-SQL Server).
Examples
The following code example specifies the command that updates metadata in the scope table in each peer database. To view this code in the context of a complete example, see How to: Provision a Server Database for Collaborative Synchronization (Non-SQL Server).
