Well, after dinking around for serveral hours I decided to beg for help
on here about triggers and look like an idiot all in one slew.
I have two tables. A and B. Whenever A has a row inserted I want to
grab that newly created primary key from it's row in table A and insert
it into a field in table B.
I have tried creating single triggers and triggers that call functions.
I even messed with rules a bit. All resulted in either "something"
happening but not seeing a change in data or flat out syntax or code
errors.
I was attempting to use: select last_value from A_A_id_seq; to get
the latest primary key. This seems to work ok on it's own.
Question is how do I incorporate that into a trigger or something
equivalent? Also, what if I have tables C and D that need to be update
the same as B is. Do I make more triggers or simply have the function
called by the trigger or the trigger itself update all three tables?
Thanks.
