sql 查询中的日期过滤器以获取今天的值

Question

我想要数据表中的链接，其中徽标链接为 <= fromdate and >= 今日。

我编写此查询是为了获取值

select *  from getlogo 

select * from getlogo 
where (Convert(date,logofrom) >= getdate()) and (Convert(date,logoto) <= getdate()) 
and active=0


 today = 03/25/2015
 from = database.value logofrom 
 to = database.value logoto     
 how to compare this and get value 

结果：

Answer 1

如果您想要徽标具有今天所在的日期范围，则反转条件：

(Convert(date,logofrom) <= getdate()) and (Convert(date,logoto) >= getdate()) 

这将在您的示例中返回带有

id = 2

的徽标。

Answer 2

您应该 CAST GetDate 以便包含边缘上的日期：

SELECT  *
FROM    getlogo
WHERE   CAST(logofrom AS DATE) <= CAST(GETDATE() AS DATE)
        AND CAST(logoto AS DATE) >= CAST(GETDATE() AS DATE)
        AND active = 0

Answer 3

如果根据您的描述，您需要第二条记录作为结果..

使用此查询

select * from getlogo where getdate() between convert(datetime,logofrom) 
and convert(datetime,logoto) and  active=0
