SELECT DATEADD(MINUTE, CEILING(DATEDIFF(SECOND, 0, CAST(CAST(PA.ORA_INIZIO AS DATETIME) AS TIME)) / 60.0), DATEDIFF(DAY, 0, PA.ORA_INIZIO)) AS BEGIN_TIME_ROUNDED
EDITAR
Como se señaló en un comentario, esto falla por tiempos entre 0 y 1 segundo. Esto se puede combatir simplemente cambiando la precisión en el techo de segundos a milisegundos:
SELECT PA.ORA_INIZIO,
DATEADD(MINUTE,
CEILING(DATEDIFF(MILLISECOND, 0, CAST(PA.ORA_INIZIO AS TIME)) / 60000.0),
DATEDIFF(DAY, 0, PA.ORA_INIZIO)) AS BEGIN_TIME_ROUNDED
FROM (VALUES
(CONVERT(DATETIME, '20211126 15:59:00.997')),
(CONVERT(DATETIME, '20211126 15:59:00.004'))
) AS PA (ORA_INIZIO);
Lo que da:
ORA_INIZIO | BEGIN_TIME_ROUNDED |
---|---|
2021-11-26 15:59:59.997 | 2021-11-26 16:00:00.000 |
2021-11-26 15:59:00.003 | 2021-11-26 16:00:00.000 |
