I would like to create a generic procedure that writes a tables column name and value to a history table if the value has changed.
Is there anyway to do that without creating an if-endif block for each column value. I don't want to do the following.
if (:old.col1 <> :new.col1) then
-- insert into history table
end if if (:old.col2 <> :new.col2) then
-- insert into history table
end if
I would like the procedure to be general enough that I don't have to modify it when I add/delete columns from a table that calls the procedure though a trigger.
