assuming using sql service. can achieve of trigger this

query

create trigger trig_update_episode on [episode] insert begin if not exists (select 1                   [dbo].[tblepisodesession] (nolock)                  [episodeid] = [inserted.id])  print n'you must update entry in tblsessionepisode well';   end
