Question

我正在尝试计算8 AM-8PM之间（例如2013年5月2日）与8 PM-8AM（次日）之间的交易次数

具有这些时间的字段称为 - CREATED_DT

所售商品的字段名为 - ITEM_ID

有人可以帮忙吗？无法在论坛上找到它。

谢谢，或

Answer 1

select count(ITEM_ID) from your_table
where CREATED_DT between '2013-05-20 08:00:00' and '2013-05-20 20:00:00'

Answer 2

像这样的东西：

SELECT 
    COUNT(1)

FROM 
    dbo.YOUR_TABLE

WHERE
    CAST(CREATED_DT AS DATE) = '03.20.2013'
    AND
    CAST(CREATED_DT AS TIME(0)) BETWEEN '08:00:00' AND '20:00:00'

MSDN：TSQL time

Answer 3

因为您正在寻找相对计数

select day2-day1 from
(
    select 
        sum(case when created_dt = '2013-05-20' then 1 else 0 end) as day1
        , sum(case when created_dt = '2013-05-21' then 1 else 0 end) as day2 
    from your_table
    where CREATED_DT between '2013-05-20 08:00:00' and '2013-05-20 20:00:00' 
    or CREATED_DT between '2013-05-21 08:00:00' and '2013-05-21 20:00:00'
)t

Answer 4

这是在上午8点到晚上8点之间给出的

select count(ITEM_ID) from your_table
    where CREATED_DT between 
    CONVERT(varchar(15),CAST('2013-05-20 08:00:00' AS TIME),100) and 
CONVERT(varchar(15),CAST('2013-05-20 20:00:00' AS TIME),100)
