How do you delete a record from a Mnesia table?

mnesia:delete/1 removes the record matching a given key, run inside a transaction just like write/1 and read/1, so the deletion participates in the same atomicity and locking guarantees.

mnesia:transaction(fun() ->
    mnesia:delete({person, 1})
end).

There's also mnesia:delete_object/1, which deletes a specific record by matching its full content rather than just its key — useful on bag tables where multiple records can share the same key and you only want to remove one particular one. A fast, non-transactional mnesia:dirty_delete/1 is also available, following the same speed-versus-consistency tradeoff as other dirty operations.
