Thank you 😊
Thanks for this but merge into can handle many other scenarios and it can get tricky
can't we do something like this trunacte table target_table_name; insert into target_table select * from source_table; if we want to have all 3 features together. Seems weird but still asking

Right. But, I think when we are dealing with tables having millions of records and only a hundreds need insert, update or delete, then merge makes more sense.
