There is nothing wrong with your syntax. There's no "limits" to what you're trying to do. So check your syntax carefully and make sure you don't have a tiny typo somewhere, or breaking a rule, etc... Get yourself some data and then chop down your Update to just updating 2 columns. If that works, then add more columns one at a time.
