sql查询中的日期过滤器获取今天的值

Question

我想要一个来自数据表的链接，其中徽标链接是＆lt; = fromdate和＆gt; = todate。

我＆＃39;编写此查询以获取值

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

如果您希望徽标的日期范围在今天下降，请反转条件：

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

这会在您的示例中返回带有id = 2的徽标。

Answer 2

您应该使用CAST GetDate来包含边缘日期：

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
