This is correct.

My guess for this request is that alot of people would rather write:

  FROM Table;

instead of:

SELECT column1, column5, column2, column3, column4
  from Table;

I've seen alot of "BEST PRACTICE" advice on this list that suggests that writing out all of the
columns is recommended.  However, I am sure that there are alot of individuals that like to write
these queries with the least amount of code possible.
