如何使用 DateAdd 过滤单个字段

Question

“FollowingTrialDate”类型为日期时间

我想在单个字段中的日期之间进行过滤。

如何在过去 15 天内的 FollowTrialDate 字段中进行过滤。

如果有错误，在哪里？

最好的问候，

SELECT C.[No],
convert(date,CaseDate,103) as ModuleDate,
convert(date,FollowingTrialDate,103) as FollowingTrialDate,
ShortDescription,
Username,
Name,
Surname,
Email,
C.[Description] as [Desc],
'Davalar' as ModuleName
FROM [LegalIT_MnemonicTEST].[dbo].[Module_Case] C 
inner join [System_User] su on C.LawyerID = su.UserID 
where CONVERT(date,FollowingTrialDate,0) 
between DATEADD(DD,-15,CONVERT(date,FollowingTrialDate,0)) and 
        DATEADD(DD,0,CONVERT(date,FollowingTrialDate,0)) 

Answer 1

试试下面的代码（如果FollowingTrialDate的类型是你的数据库中指定的日期时间）

请注意，如果您的 CaseDate 或 FollowTrialDate 已在数据库中指定的“日期时间”类型中，则无需先将其转换为日期以用于输出或过滤 WHERE 子句中使用的数据

SELECT C.[No],
convert(datetime,CaseDate) as ModuleDate,
FollowingTrialDate,
ShortDescription,
Username,
Name,
Surname,
Email,
C.[Description] as [Desc],
'Davalar' as ModuleName
FROM [LegalIT_MnemonicTEST].[dbo].[Module_Case] C 
inner join [System_User] su on C.LawyerID = su.UserID 
where FollowingTrialDate
between DATEADD(DAY, DATEDIFF(DAY, 0, dateadd(dd, -15, getdate())), 0) and 
        DATEADD(DAY, DATEDIFF(DAY, 0, getdate()), 0)
