My untrained eye can't spot any particular code smells. Though I have learned to use fetchrow_hashref, because it means you don't have to care about the order of the returned data, you just use the field names, but it does force you to learn about references. The code you have is already pretty concise and would only need a little more formatting to be more readable.
Also note that if you don't need the code you commented out, get rid of it or it will accumulate. I know it's something I have to fix in my own code. The odd #print ... is OK, but if you have version control you don't need big blocks of code commented out 'just in case you need to uncomment it one day'
