Display 1st row of every group?

[Dan Bolser]

I read with great interest this 

http://www.artfulsoftware.com/queries.php#4

Display 1st row of every group

SELECT id
FROM tbl
GROUP BY id
HAVING count(*) = 1;

I want to use this syntax with an 'order by' like this...

  SELECT *
    FROM tbl
GROUP BY id
  HAVING count(*) = 1
ORDER BY bleah;

Will this syntax return the row within the "id group" with the smallest
value of the bleah column? (is it guaranteed to do so?)

Cheers,
Dan.
