I don't see microseconds as a possible field in SQL:2003 (draft copy).

MySQL 5.0.16 gives an error:

mysql> SELECT EXTRACT (MICROSECOND FROM '2003-01-02 10:30:00.00123');
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax to use
