Hi,
Can anybody give me some example where complex business rule cannot be implemented by constraints, but triggers can do it.
"Enforce complex business or referential integrity rules that you cannot define with constraints "
the above line mentions the property of triggers . So, I need such an example for the above statement.

Can any one plz....
