Dear all, I've a table where the date is separated in single fields, one for year, one for day and one for month. So I need to query for a date range. I search in Internet and I found the following query that seems to be works: SELECT * FROM plan WHERE year * 10000 + month * 100 + day BETWEEN +'20130101' AND '20130131';
Now I'm trying to translate to sqlalchemy, but I receive the following error: DataError: (DataError) invalid input syntax for integer: "2013-01-01T00:00:00" LINE 3: ...year * 1000 + plan.month * 100 + plan.day BETWEEN '2013-01-0... ^ 'SELECT plan.data AS plan_data, plan.month AS plan_month, plan.instrument_id AS plan_instrument_id, count(plan.instrument_id) AS count_1 \nFROM plan \nWHERE plan.year * %(year_1)s + plan.month * %(month_1)s + plan.day BETWEEN %(param_1)s AND %(param_2)s AND plan.data ILIKE %(data_1)s GROUP BY plan.data, plan.month, plan.instrument_id ORDER BY month, instrument_id' {'data_1': u'%#L%', 'param_1': datetime.datetime(2013, 1, 1, 0, 0), 'month_1': 100, 'year_1': 1000, 'param_2': datetime.datetime(2013, 10, 3, 0, 0)} The latest attempt to write the correct code is the following (the range come from a web form using a javascript plugin): from_date = request.POST.get('from_date', '') to_date = request.POST.get('to_date', '') from_date = datetime.strptime(from_date, '%Y-%m-%d') to_date = datetime.strptime(to_date, '%Y-%m-%d') if from_date.day < 10: day = "0%s" % from_date.day else: day = "%s" % from_date.day if from_date.month < 10: month = "0%s" % from_date.month else: month = "%s" % from_date.month if to_date.day < 10: tday = "0%s" % to_date.day else: tday = "%s" % to_date.day if to_date.month < 10: tmonth = "0%s" % to_date.month else: tmonth = "%s" % to_date.month fd = '%s%s%s' % (from_date.year, month, day) td = '%s%s%s' % (to_date.year, tmonth, tday) print fd, td results = Session.query(Plan.data, Plan.month,Plan.instrument_id,func.count(Plan.instrument_id)).filter( and_((Plan.year*1000+Plan.month*100+Plan.day).between(from_date, to_date), Plan.data.ilike('%%%s%%' % item),)).group_by( Plan.data, Plan.month, Plan.instrument_id ).order_by('month', 'instrument_id').all() Where I'm wrong?
