Looking at this example to do bulk inserts, I assumed using the same logic would work for updates. I tried to the following to see if it would work, and it does not:

you cant pass a array as a parameter.
What you can do is loop through your array and call the update for each position of the array (whihc wouldnt really be a "bulk" insert), or you can use something like:
WHERE NAME in ("Test1", "Test2", "Test3", "Test4", "Test5")
and so on
It turns out I had my parameter names flipped. Took me forever to find it.
