Question

这是我的程序，我无法获取特定日期的记录..

我有特定日期的数据，但输出为零.. 但是当我使用＆gt; =它给我数据..

使用= @Date作为参数给出零输出..

使用＆gt; = @Date作为参数提供输出

我的程序在哪里需要修改以根据提供的日期获取数据。

Declare @ids varchar(max);    
set @ids = (select ids from USers where UserId = 10)      
  select F.Date as DateOfuser,F.ID , (B.FirstName + ',' + B.LastName) as Name,    
A.Group ,E.companyname,E.company ,D.receivedDate    
from Details as A    
inner join Usersnew as B    
on A.newId = B.newId    
inner join Files as D    
on D.DocId = B.Docid    
Inner join PDetails as C    
on (D.GId = c.GId and D.PId = C.Id and D.IsActive='True' and             
(convert(datetime,D.ReceivedDate, 20) = @Date  ))  -- @parameter @date // no output       
and D.GId in(select ID from fnSplitter(@ids))    
inner join PDetails as E    
on E.PId = C.Id    
inner join Information as F    
on F.PId = E.PId

如何获取作为参数传递的特定日期的记录..

我有数据，但它没有返回我如何修改我的程序来获取数据

我需要根据日期得到输出。我有通过日期收到的数据，所以日期作为参数传递..

请帮帮忙？

任何想要获取作为参数传递的特定日期的记录吗？

为什么

=未返回＆gt; =正在返回

你可以解释一下吗？

我们在等于传递日期的过程中传递=操作数？

@Simon说。比较日期和日期时间可能存在问题。比较日期和日期时间时，日期会转换为日期时间，例如“2017-07-04”投放至“2017-07-04 00：00：00.000”。更改行：

    on (D.GId = c.GId and D.PId = C.Id and D.IsActive='True' and             
(convert(datetime,D.ReceivedDate, 20) = @Date  ))

为：

on (D.GId = c.GId and D.PId = C.Id and D.IsActive='True' and
(convert(datetime,D.ReceivedDate, 20) >= @Date) AND (convert(datetime,D.ReceivedDate, 20) < DATEADD(dd,1,@Date)))

您也可以将其更改为：

on (D.GId = c.GId and D.PId = C.Id and D.IsActive='True' and             
(cast(D.ReceivedDate as date) = @Date  ))

如何从特定日期...通过程序从数据库中获取记录。日期作为参数
