SQL-запрос не упорядочен по времени и дате

Question

Я работаю над своим запросом sql, где я заказываю по времени и дате, но не уверен, почему он не упорядочивает правильно. Показана дата 29 до 30 .:

SELECT measurements.title as Tittel, routines.value as Verdi, CONVERT(VARCHAR(10),routines.date,103) as Dato, convert(VARCHAR(10), routines.time, 108) as Tid, pools.name as Basseng, emps.user_name as Ansatt 
FROM routines, measure_routine, measurements, pools, emps 
WHERE routines.id = measure_routine.routine_id 
AND measure_routine.measure_id = measurements.id 
AND (measurements.title Like 'T_%') AND measure_routine.pool_id=pools.id AND routines.emp_id=emps.id 
AND Date between '2014-04-29' and '2014-04-30' 
order BY routines.date, routines.time 

Answer 1

Это потому, что сортировка по возрастанию. Если вам нужно 29 после 30, вам нужно спуститься.

SELECT measurements.title as Tittel, routines.value as Verdi, CONVERT(VARCHAR(10),routines.date,103) as Dato, convert(VARCHAR(10), routines.time, 108) as Tid, pools.name as Basseng, emps.user_name as Ansatt 
FROM routines, measure_routine, measurements, pools, emps 
WHERE routines.id = measure_routine.routine_id 
AND measure_routine.measure_id = measurements.id 
AND (measurements.title Like 'T_%') AND measure_routine.pool_id=pools.id AND routines.emp_id=emps.id 
AND Date between '2014-04-29' and '2014-04-30' 
order BY routines.date desc, routines.time desc
