upsert strategies?

So far, I've figured out 4 possible ways to perform upsert-like functionality:

  1. try insert, on exception update
  2. try update, on exception insert
  3. delete, then insert
  4. merge with DUAL

It seems so far the nicest solution is #4.

Here's some questions:

  • Do the other methods have any features which might recommend them?
  • Are there any methods that might be portable to other databases?
  • Are there any methods I might be overlooking?

Many TIA!
