Question

我想从rfq_create_date_time中提取时间部分，只选择两次之间的记录。时间是格林尼治标准时间，但我只对香港时区的记录感兴趣，即格林尼治标准时间23.00至格林尼治标准时间10.00。

时间字段已成功创建（rfq_create_time）：

SELECT
   *
FROM
(
    select      
                R.created_date_time,
                R.rfq_create_date_time,
                cast(R.rfq_create_date_time as time) as rfq_create_time,
    from        [ecomm_rfq].[dbo].[RFQ]                 R   WITH (NOLOCK) 
                join [ecomm_rfq].[dbo].[RFQ_RFQLEG]     L   WITH (NOLOCK)   
                on R.unique_id = L.unique_id                --inner join
    where
                R.rfq_create_date_time >= '2018-06-01'
                and R.rfq_create_date_time <= '2018-06-30'          
)       as innerTable

WHERE rfq_create_time between ('23:00:00.0000000' and '10:00:00.0000000')
order by rfq_create_time

between操作符抛出以下错误：

Incorrect syntax near the keyword 'and'.

是否有一种方法可以基于跨午夜的“时间”字段选择行？

Answer 1

尝试以下操作：

SELECT
   *
FROM
(
    select      
                R.created_date_time,
                R.rfq_create_date_time,
                cast(R.rfq_create_date_time as time) as rfq_create_time,
    from        [ecomm_rfq].[dbo].[RFQ]                 R   WITH (NOLOCK) 
                join [ecomm_rfq].[dbo].[RFQ_RFQLEG]     L   WITH (NOLOCK)   
                on R.unique_id = L.unique_id                --inner join
    where
                R.rfq_create_date_time >= '2018-06-01'
                and R.rfq_create_date_time <= '2018-06-30'          
)       as innerTable

WHERE rfq_create_time not between '10:00:00.0000000' and '23:00:00.0000000'
order by rfq_create_time

Answer 2

Braces should be included only if u want to make this computation in prior to additional arithmetic operations but not prefered for datetime operations Hence

this is wrong rfq_create_time between ('23:00:00.0000000' and '10:00:00.0000000')

This is correct rfq_create_time between '23:00:00.0000000' and '10:00:00.0000000'
