Question

SQL Server 2008。有没有办法连接下面的内容并删除00:00:00:000？

*编辑 - 完整列包含日期列表

SELECT DISTINCT
    DATEADD(dd, -(DATEPART(dw, fulldate)-1), fulldate) [WeekStart], 
    DATEADD(dd, 7-    (DATEPART(dw, fulldate)), fulldate) [WeekEnd]
FROM time
WHERE YEAR(time) >= 2016
ORDER BY WeekStart

结果：

WeekOf

12-27-2015-01-02-2016

等等...

Answer 1

由于dateadd返回date而非字符串 - 您必须首先使用适当的format（在您的情况下为110）将值转换为字符串，然后将它们连接起来：

select distinct
    convert(nvarchar(20), DATEADD(dd, -(DATEPART(dw, fulldate)-1), fulldate), 110) + '-' + 
    convert(nvarchar(20), DATEADD(dd, 7-    (DATEPART(dw, fulldate)), fulldate), 110) as WeekOf
from time
where YEAR(time) >= 2016
order by WeekStart

连接DATEADD＆amp; DATEPART
