SELECT Code,Description FROM TABLE

-- This will Include only date part of 14th March 2010. Any date with date companents will not be considered.
WHERE ID= 1 AND FromDate >= CONVERT(DATETIME, '2010-02-14', 126) AND ToDate <= DATEADD(dd, 1, CONVERT(DATETIME, '2010-03-14', 126))

-- This will Include the whole day of 14th March 2010
--WHERE ID= 1 AND FromDate >= CONVERT(DATETIME, '2010-02-14', 126) AND ToDate < DATEADD(dd, 1, CONVERT(DATETIME, '2010-03-14', 126))

还有一种方法……

CONVERT(varchar, DATEPART(yyyy, @datetime)) + '/' + CONVERT(varchar, DATEPART(mm, @datetime)) + '/' + CONVERT(varchar, DATEPART(dd, @datetime)) 

您所需要的表格在图书在线文档中列出。

例如，尝试以下方法:

select convert(varchar,getDate(),120)
select convert(varchar(10),getDate(),120)

将GetDate()更改为字符串格式:

SELECT FORMAT(GetDate(), 'yyyy-MM-dd HH:mm:ss')

使用每个转换/强制转换函数的CASE语句总是为我工作:

请将tableXXXXY替换为您的表名，并将issueDate_dat替换为该表中的datetime字段的名称:

SELECT  issueDate_dat, CONVERT(varchar, DATEPART(yyyy, issuedate_dat))  AS issueDateYYYY
, CASE WHEN (len(CONVERT(varchar, DATEPART(mm, issuedate_dat))) < 2) THEN '0' +CONVERT(varchar, DATEPART(mm, issuedate_dat)) ELSE CONVERT(varchar, DATEPART(mm, issuedate_dat)) END AS  issueDateMM
, CASE WHEN (len(CONVERT(varchar, DATEPART(dd, issuedate_dat))) <2) THEN '0' +CONVERT(varchar, DATEPART(dd, issuedate_dat)) ELSE CONVERT(varchar, DATEPART(dd, issuedate_dat)) END AS issueDateDD
FROM            tableXXXXY

希望这对你有帮助。chagbert。

这个方法对我来说很有效，简单有效(也有126条)

CONVERT(NVARCHAR(MAX), CAST(GETDATE() as date), 120)
