of updating/inserting. What is the resultant query you wish these actions to
make easier/faster - instead of what you want to implement.
Certainly you can trigger this action on tables or you can use an
update/insert SP to do it for you. But I smell some other issues.
After these actions have been taken, what query do you want to use and what
is the expected answer from it?
