Suppose you have a table T:

----------------------

A      B

----------------------

1     '111'

2     '222'

----------------------

How do you select A and B of the record with A maximum?

The desirable result therefore is (2, '222')

The two variants I could grow with are:

1) SELECT A, B FROM T ORDER BY A DESC LIMIT 1

2) SELECT A, B FROM T WHERE A IN (SELECT MAX(A) FROM T)

What do yo think of the queries above? And give me the better implementation
if possible.
