I have a table that among other things has a name, address, city, state
fields. When I insert into, I want to be able to make sure that there is
no duplicate records or that a row is inserted that is already in the DB.
Question number one is: Should I use a trigger or a rule?
And request number two is perhaps a sample that could get me started.
I've read thru the Documentation and Man pages and tried creating a rule
but, had no luck.
Thanks in advance.
Andy
