I would like to prevent changes being made to a table (b), except when a
trigger fires as a result of changes (insert,update) being made to
another table (a). Should any changes be made to table b by any other
means than the trigger from table a, I would like to trap those changes
(again, could I use a trigger?) and make sure that the original values
in table b stays the same.
Can anybody point me in the right direction please.
