How to read datetime back from sqlite as a datetime instead of string in Python?

Question

I\'m using the sqlite3 module in Python 2.6.4 to store a datetime in a SQLite database. Inserting it is very easy, because sqlite automatically converts the date to a string

Answer 1

If you declare your column with a type of timestamp, you're in clover:

>>> db = sqlite3.connect(':memory:', detect_types=sqlite3.PARSE_DECLTYPES)
>>> c = db.cursor()
>>> c.execute('create table foo (bar integer, baz timestamp)')

>>> c.execute('insert into foo values(?, ?)', (23, datetime.datetime.now()))

>>> c.execute('select * from foo')

>>> c.fetchall()
[(23, datetime.datetime(2009, 12, 1, 19, 31, 1, 40113))]

See? both int (for a column declared integer) and datetime (for a column declared timestamp) survive the round-trip with the type intact.
