Question

我需要在午夜之前和午夜之间使用24小时日期时间的字段计算记录。以下陈述适用于同一天的时间，例如：上午10:30到下午4:29之间：

WHERE CAST (theader_tdatetime AS time) BETWEEN '10:30' and '16:29'

但是，我还需要从晚上7:31到凌晨2:00选择记录，我的陈述不再有效：

WHERE CAST (theader_tdatetime AS time) BETWEEN '19:31' and '02:00'

如何从这段时间内选择记录？

Answer 1

WHERE CAST (transaction_date AS time)
BETWEEN '15:30 PM' and '23:59 PM' 
or CAST (transaction_date AS time) BETWEEN '0:00 AM' and '02:00 AM'

Answer 2

WHAST CAST（theader_tdatetime AS time）＆gt; = '19：31'或CAST（theader_tdatetime AS time）＆lt; = '02：00'

午夜之前和之后的SQL Server计数 - 24小时
