Code:
SELECT *

WHERE ( zdate = date_in and ztime >= time_in )
OR ( zdate > date_in AND zdate < date_out )
OR ( zdate = date_out and ztime <= time_out )
но только будет ли это быстрее, чем выборка по датам и отсечение записей в LOOP _________________ С уважением,

Изначально в коде и был такой селект, но практика показала его неправильную работу
