Question

我正在尝试使用以下sql查询从表中获取记录。

SELECT Code,Description FROM Table
WHERE ID= 1 AND FromDate >= '2010-02-14' AND ToDate <= '2012-03-14'

即使此日期存在记录，查询也不会返回任何内容。

ID HID HCode HDescription FromDate            ToDate 
-------------------------------------------------------------------
1  3   H8    New Year     2012-03-14 12:38:00 2012-03-14 12:38:00

请给我一个合适的解决方案。谢谢你的时间!!

Answer 1

试试这个：

declare @dayAfter datetime     --let take 1 day after

set @dayAfter = DateAdd(day,1,'20120314')

SELECT Code,Description FROM Table
WHERE ID= 1 AND 
FromDate >= '20100214' AND 
ToDate <  DateAdd(day, DateDiff(day, 0, @dayAfter ), 0)

p.s：

DateAdd(day, DateDiff(day, 0, @dayAfter ), 0)会将时间重置为00:00

所以你需要desired EndTime < begining of the day after

Answer 2

如果您在FromDate和ToDate之间选择数据，则删除ID = 1。在这种情况下，Аs是ID = 1的选定记录，FromDate和ToDate选中此条目。

Answer 3

尝试使用以下查询，它肯定会解决您的问题....

SELECT Code,Description FROM Table
   WHERE ID= 1 AND
         CONVERT(VARCHAR(10), FromDate, 101)>= CONVERT(VARCHAR(10),CAST('2010-02-14' AS DATETIME),101) AND 
         CONVERT(VARCHAR(10), ToDate, 101)<= CONVERT(VARCHAR(10),CAST('2012-03-14' AS DATETIME),101) ;

Answer 4

您正在从ragne中选择数据

FromDate >= '2010-02-14 00:00:0000' AND ToDate <= '2012-03-14 00:00:0000'

你应该这样做：

FromDate >= '2010-02-14' AND ToDate < '2012-03-15'

Answer 5

SELECT *
 FROM  table
