Hi Niklas, As stated above, you can not use the string literal to query, you must include a DATETIME() wrapper around that argument. Additionally, since milliseconds are not included, you would need to query something like this to find a specific entity that accorded at 2008-06-08 22:17.45.xxxx:
SELECT * FROM thing WHERE date > DATETIME(\'2008-06-08 22:17.45\') AND date < DATETIME(\'2008-06-08 22:17.46\') -Marzia On Thu, Nov 20, 2008 at 1:09 PM, niklasr <[EMAIL PROTECTED]> wrote: > > Thank you for replying, though it's still not matching from here. > I've this is the datastore > added YYYY-MM-DD HH:MM:SS > value: 2008-06-08 22:17:45.200477 > type: gd:when > > Still the following won't match > SELECT * FROM thing WHERE added = '2008-06-08 22:17:45' > > It should be trivial, but how? > > regards > Niklas > > On Nov 20, 7:56 pm, Marzia Niccolai <[EMAIL PROTECTED]> wrote: > > Hi, > > > > In order to query on DateTime objects, the following methods are > supported > > (fromhttp://code.google.com/appengine/docs/datastore/gqlreference.html): > > > > A datetime, date, or time literal, with either numeric values or a string > > representation, in the following forms: > > * DATETIME(year, month, day, hour, minute, second) > > * DATETIME('YYYY-MM-DD HH:MM:SS') [no milliseconds] > > * DATE(year, month, day) > > * DATE('YYYY-MM-DD') > > * TIME(hour, minute, second) > > * TIME('HH:MM:SS') > > > > -Marzia > > > > On Wed, Nov 19, 2008 at 7:03 PM, niklasr <[EMAIL PROTECTED]> wrote: > > > > > SELECT * FROM thing WHERE added = '2008-06-08 22:17:45.200477 ' > > > won't match > > > Neither > > > SELECT * FROM thing WHERE added < '2008-07-08 22:17:45.200477 ' and > > > added > '2008-06-08 22:17:45.200477 ' > > > And > > > SELECT * FROM Ad WHERE added < '2006-11-18 22:17:45.200477 ' > > > surprisingly matches many entities. > > > > > How match a day or a month interval, or an exact timepoint? > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
