对于给定日期，查询应返回特定日期的周名称。

DECLARE @Date DATE ='2014-06-02 00：00：00.000'

如果我给出上述日期，则应返回该特定周的周名称。

我的SQL查询是

DECLARE @StartDate DATETIME = '2014-06-02 00:00:00.000'
DECLARE @EndDate DATETIME = '2014-06-09 23:59:59.999'

SELECT CONVERT(VARCHAR(10),DATEDIFF(HOUR,@StartDate,@EndDate))+'.' 
+CONVERT(VARCHAR(10),DATEDIFF(MINUTE,@StartDate,@EndDate)% 60)
AS NoOfHours

帮助我在SQL Server 2008中选择查询

以下是查询：

DECLARE @Date DATE = '2014-06-02'


;WITH CTE AS
(
  SELECT @Date [Date],
         DATENAME(DW,@Date) DayOfTheWeek,
         1 i

  UNION ALL

  SELECT DATEADD(DAY,1,[Date]),
         DATENAME(DW,DATEADD(DAY,1,[Date])),
         i + 1
  FROM CTE
  WHERE i + 1 <=7
)
SELECT DayOfTheWeek,
       [Date]
FROM CTE
ORDER BY i ASC
