Yes, it can be done,
I'd write the trig to do a select on that PK and if %FOUND is true, update otherwise in the exception handler for that block, do the insert.

begin
..
begin

        select PK from table;
        UPDATE
exception
        INSERT

end
..
end

Listers,

I am attempting to write a trigger on a table that will have batch inserts nightly. I want each insert to check to see if a record with that primary key exists, and if it does, update the record. If the primary key does not yet exist in the table, insert the record. The batch load each night is a large series of inserts, no updates. I want the trigger to figure out it if needs to update or insert.

Can this be done??

Thank you,
