Thanks for clarification. My understanding:
Process creating notified function has to create trigger & do the other operation (Update, Insert and Delete) to get trigger logic execution. I understand it may not be in same sequence. Process can register function & create trigger, But trigger operation may come on run time .(All by using common sqlite handler...) >Which part of this sentence did you find unclear the first time round? It is all clear!!!! I was just checking for hint, if some one comes across to handle this kind of scenario by using combination of sqlite capability & application logic!!!
