The first is correct but the second is wrong.
However, even with this said, you may hear the second sentence from native speakers in casual conversations. As I mentioned in this answer, some people tend to reverse orders while speaking. For example &quot;山东人我是&quot;. But don't get me wrong: this sentence is not correct and you should not say the same. However, just don't be surprised if you hear some native speakers make the same mistake.
