Question

是否可以根据以下代码跟踪每天的日期（周一至周日）？

DECLARE @DATA TABLE(
    Movie1 DATETIME,
    Movie2 DATETIME,
    Movie3 DATETIME,
    Movie4 DATETIME,
    Movie5 DATETIME
)
INSERT INTO @DATA
SELECT '01/20/2010','02/15/2010','02/02/2010','03/31/2010','04/16/2010'

Answer 1

如果您问如何退回文字，例如根据日期“星期一”，请查看MSDN上的DATENAME功能。

select datename(weekday, Movie1) from @DATA

Answer 2

试试这个：

select 
datename(dw, Movie1) Movie1Day,
datename(dw, Movie2) Movie2Day,
datename(dw, Movie3) Movie3Day,
datename(dw, Movie4) Movie4Day,
datename(dw, Movie5) Movie5Day
from @DATA

什么日期基于日期时间
