Description
Defines a method that modifies a record.
Datasnap.Provider.TSQLResolver.DoUpdate inherits from Datasnap.Provider.TCustomResolver.DoUpdate. All content below this line refers to Datasnap.Provider.TCustomResolver.DoUpdate.
Defines a method that modifies a record.
DoUpdate is one of several helper methods internal to the ApplyUpdates method. These helper methods perform the actual updates passed in the delta packet. ApplyUpdates wraps the delta packet in a TUpdateTree object. For each record that must be modified, the resolver calls DoUpdate.
TCustomResolver does not implement the DoUpdate method. Descendants override this method to insert records in their own specialized way.
