Question

基本上我想要做的就是在

之间调整范围

已经得到了这个

where @param_value_from_hour between From_Hour and To_Hour

当@param_value_from_hour让我们说16:00时它会起作用，但如果我必须在19:00搜索@param_value_from_hour怎么办？

Answer 1

将time列转换为datetime并进行比较

declare @param_value_from_hour varchar(20) = '19:00'
;with myTable as (
    select * 
    from (
        values 
            (1, '7:00:00', '18:00:00')
            , (2, '18:00:00', '7:00:00')
    ) t(Shift, From_Hour, To_Hour)
)

select
    * 
from
    myTable
where
    cast('20180101 ' + @param_value_from_hour as datetime) between 
    cast('20180101 ' + From_Hour as datetime) 
    and cast('20180101 ' + To_Hour as datetime) + case when From_Hour < To_Hour then 1 else 0 end

Answer 2

如果逻辑是这样，如果期间的结束早于期间的开始，则假定期间跨越午夜（如果不是，我们需要一些其他形式的约定或事情得到绝望的含糊不清）：

where
   (@param_value_from_hour between From_Hour and To_Hour) or
   (To_Hour < From_Hour and
       (@param_value_from_hour < To_Hour or
        From_Hour < @param_value_from_hour)
   )

应该大致得到你想要的东西（如果需要，调整< {/ 1}}

Answer 3

试试这个：

CREATE TABLE Data (
    Shift INT,
    FromHour TIME,
    ToHour TIME
    );

INSERT INTO Data (Shift, FromHour, ToHour) VALUES
(1, '07:00:00', '18:00:00'),
(2, '18:00:00', '07:00:00');

DECLARE @Param TIME= '16:00:00'; --Change that to '19:00:00'

SELECT *
FROM Data
WHERE CAST(@Param AS DATETIME) BETWEEN 
      CAST(FromHour AS DATETIME)
        AND
    (CASE 
         WHEN (@Param >= '18:00:00' AND ToHour = '07:00:00') 
             THEN DATEADD(D, 1, CAST(ToHour AS DATETIME)) 
         ELSE CAST(ToHour AS DATETIME) 
    END)

Answer 4

感谢您的所有宝贵回复

所以这是2个答案结合的答案

declare @param_value_from_hour varchar(20) = '19:00'

;with myTable as (
    select * 
    from (
        values 
            (1, '07:00:00', '15:00:00')
            , (2, '15:00:00', '23:00:00')
            , (3, '23:00:00', '07:00:00')
    ) t(Shift, From_Hour, To_Hour)
)

select
    * 
from
    myTable
where
   (@param_value_from_hour between From_Hour and To_Hour) or
   (To_Hour < From_Hour and
       (@param_value_from_hour < To_Hour or
        From_Hour < @param_value_from_hour)
   )

谢谢你们，你真棒！
