-# Tests to make sure that values returned by changes() and total_changes()
-# are updated properly, especially inside triggers
-#
-# Note 1: changes() remains constant within a statement and only updates
-#         once the statement is finished (triggers count as part of
-#         statement).
-# Note 2: changes() is changed within the context of a trigger much like 
-#         last_insert_rowid() (see lastinsert.test), but is restored once
-#         the trigger exits.
-# Note 3: changes() is not changed by a change to a view (since everything
-#         is done within instead of trigger context).
