DbSyncProvider.UpdateScopeCleanupTimestampCommand Property

Gets or sets an IDbCommand object that contains the query or stored procedure that updates the scope_cleanup_timestamp column for a particular scope in the scope_info table, to mark the point up to which cleanup has been performed for the scope.

Namespace:  Microsoft.Synchronization.Data
Assembly:  Microsoft.Synchronization.Data (in Microsoft.Synchronization.Data.dll)

public virtual IDbCommand UpdateScopeCleanupTimestampCommand { get; set; }

Property Value

Type: System.Data.IDbCommand
An IDbCommand object that contains a query or stored procedure.

The following code example specifies a command for the UpdateScopeCleanupTimestampCommand property. This command and the command that is specified for the SelectOverlappingScopesCommand property enable Sync Framework to handle cleanup appropriately in cases where a table is included in more than one scope. To view this code in the context of a complete example, see How to: Clean Up Metadata for Collaborative Synchronization (Non-SQL Server).
