如果日期時間在特定時間間隔內使用SQL進行查找

Question

如何查看錶格中的日期時間列是否處於特定小時間隔（例如13:07 - 15:15）和特定日期（例如，星期四）在SQL select語句中？

感謝，

Answer 1

日和開始/結束小時作爲參數

declare @tbl table (datecol datetime) 

declare @startHour int 
declare @endHour int 
declare @specificDay varchar(10) 

set @startHour = 13 
set @endHour = 15 
set @specificDay = 'Thursday' 

insert into @tbl select getdate() 
insert into @tbl select dateadd(hh, 1, getdate()) 
insert into @tbl select dateadd(n, 10, getdate()) 
insert into @tbl select dateadd(dd, 2, getdate()) 

select * from @tbl 
where DATENAME(dw, datecol) = @specificDay 
and datepart(hh, datecol) >= 13 
and datepart(hh, datecol) <= 15 

編輯：

declare @tbl table (datecol datetime) 

declare @startHour varchar(10) 
declare @endHour varchar(10) 
declare @specificDay varchar(10) 

set @startHour = '13:05:00' 
set @endHour = '15:30:00' 
set @specificDay = 'Thursday' 

insert into @tbl select getdate() 
insert into @tbl select dateadd(hh, 1, getdate()) 
insert into @tbl select dateadd(n, 10, getdate()) 
insert into @tbl select dateadd(dd, 2, getdate()) 

select * from @tbl 
where DATENAME(dw, datecol) = @specificDay 
and CONVERT(VARCHAR(8), datecol,8) >= @startHour 
and CONVERT(VARCHAR(8), datecol,8) <= @endHour 

如果時間有小時和分鐘零件只有像'13：05'那麼這樣改變它

and CONVERT(VARCHAR(5), datecol,8) >= @startHour 
and CONVERT(VARCHAR(5), datecol,8) <= @endHour 

Answer 2

可以使用BETWEEN關鍵字。如... WHERE MyDate BETWEEN Date1 and Date2

Answer 3

select * From #t 

Where DatePart(hour, [date]) >=10 
and DatePart(hour, [date]) <= 11 

And DatePart(minute, [date]) >= 15 
And DatePart(minute, [date]) <= 45 

and Datename(dw,[date]) = 'Thursday' 

Answer 4

我通常使用的語法如下：

DECLARE @FromTime DATETIME 
DECLARE @ToTime DATETIME 
SET @FromTime = '2010-09-02T13:00:00' 
SET @ToTime = '2010-09-02T15:00:00' 

SELECT Something 
FROM MyTable 
WHERE DateField >= @FromTime 
    AND DateField < @ToTime 

你可以使用BETWEEN，但我通常喜歡上面的，而不是爲之間包容例如在這個例子中，使用BETWEEN將包括記錄，其中所述時間爲15：00：00.000周的
