If you were using Oracle or Microsoft SQL, you could use the MERGE. However, MySQL does not have a direct correlation to that statement. There is the single-row solution that you mentioned but, as you pointed out, it doesn't do bulk very well. Here is a blog post I found on the difference between Oracle and MySQL and how to do what Oracle does with MERGE in MySQL:

It isn't a pretty solution and it probably isn't as full a solution as you would like, but I believe that is the best there is for a solution.
