Is there a way to know if TAdoQuery in Edit state was changed?
Assuming we forced it into edit state, and we want to ask the user if he wants to keep the changes.
回答1:
You have the TADOQuery.Modified property e.g:
if ADOQuery1.State in [dsEdit, dsInsert] and (ADOQuery1.Modified) then
if KeepChanges then
ADOQuery1.Post
else
ADOQuery1.Cancel;
