Many thanks! Problem solved with numeric form matching the expected
result:
SELECT * FROM thing WHERE date > DATETIME(2008,06,08,22,17,45) AND
date < DATETIME(2008,06,08,22,17,46)
SELECT * FROM thing WHERE date > DATETIME(2008,11,20,22,17,45)
It's just that datetime string representations return error:
SELECT * FROM thing WHERE date > DATETIME('2008-06-08 22:17.45')
« An error has occurred while executing this query.
SELECT * FROM thing WHERE date > DATETIME('2008-06-08 22:17.45') AND
date < DATETIME('2008-06-08 22:17.46')
« An error has occurred while executing this query.
