问如何从SQLite中读取日期时间作为日期时间而不是Python中的字符串？

EN

>>> db = sqlite3.connect(':memory:', detect_types=sqlite3.PARSE_DECLTYPES)
>>> c = db.cursor()
>>> c.execute('create table foo (bar integer, baz timestamp)')
<sqlite3.Cursor object at 0x40fc50>
>>> c.execute('insert into foo values(?, ?)', (23, datetime.datetime.now()))
<sqlite3.Cursor object at 0x40fc50>
>>> c.execute('select * from foo')
<sqlite3.Cursor object at 0x40fc50>
>>> c.fetchall()
[(23, datetime.datetime(2009, 12, 1, 19, 31, 1, 40113))]
