Retrieves a unique identifier for a SqlCacheDependency object.
public:
override System::String ^ GetUniqueID();
public override string GetUniqueID ();
override this.GetUniqueID : unit -> string
Public Overrides Function GetUniqueID () As String
Returns
The unique identifier for the SqlCacheDependency object, or null if no identifier can be generated.
Remarks
The SqlCacheDependency method returns an identifier used to uniquely track SqlCacheDependency objects associated with an item or application. The unique identifier generated when using table-based notifications is partially dependent on the change identifier generated by the database.
When using SQL Server 2005-based query notifications, the unique identifier is null
because SQL Server 2005 does not support returning unique identifiers for individual query notifications .
