[Quoted] I have a table called 'SHOW' that will soon be changed to allow an end user to associate a 'SHOW_ID' with a 'channel_ID' or an episode_ID (but not both). This means that show will contain nullable FKs to channel and network. Can I write a mutex trigger to require that one is set but not both?
if so can somone provide an example?
thanks
