The PartialCachingAttribute.SqlDependency string identifies databases and table names according to the name of a SQL Server cache dependency in your configuration (typically added using the sqlcachedependency configuration elements). If you use SQL Server 2005, you can set the PartialCachingAttribute.SqlDependency property to "CommandNotification", which instructs ASP.NET to create row level dependencies for all SQL commands issued within the context of the current ASP.NET page.
