查询每日规定时间段内的记录

CREATE TABLE [dbo].[T](
[KSSJ] [datetime] NULL,
[JSSJ] [datetime] NULL
)

思路:从datetime字段中提取时间字段进行比较,同时,可以直接用datetime字段限定日期返回

INSERT INTO T VALUES (dateadd(hh,-8,getdate()),convert(varchar,getdate(),120));

INSERT INTO T VALUES (convert(varchar,'2019-01-02 16:20:38',120),convert(varchar,getdate(),120));
--truncate table t

select kssj from t 
where kssj <= convert(varchar,'2019-01-10 16:30:00',120) and
kssj >= convert(varchar,'2019-01-02 16:30:00',120) and
(convert(varchar,kssj,8)>convert(varchar,'16:30:00',8) or
convert(varchar,kssj,8)<convert(varchar,'08:00:00',8))

查询规定时间段内的记录

备用:
