Thomas,
All that this does is report the number of rows. It does not deal with any
columns within the table. If I had two tables with the exact number of
rows, but one table had 10 2K columns fully populated, and the other table
had 10 1-char columns fully populated, this query would return the same
result.
I'm not really sure what value this query has.

This will get you that actual bytes used by the data in the table; however,
it will hit every row in the table and take a long time to run. It takes
one parameter, the table being sized.
