I am reading Administering SQL Server, a study guide for 70-228
on page 27, it says:
"INSTEAD OF triggers are useful when a DML operation is unsuccessful."
I think this is nonsense. Any comments?
Without any context at all, the sentence certainly looks funny. It reminds
of what I once read in a manual from DEC: "Frequently, unexpected errors are
entirely unpredictable."
I guess what they are trying to say is that when you cannot insert, update
or delete directly on a view, because the view does not live up to the
rules, then you can achieve this with an INSTEAD OF trigger.
