需要有关 sql server 2008 中的 pivot 子句的帮助.我有一张包含此信息的表格:

Need help with the pivot clause in sql server 2008. I have a table with this info:

Weekno DayOfWeek FromTime ToTime1 2 10:00 14:001 3 10:00 14:002 3 08:00 13:002 4 09:00 13:002 5 14:00 22:003 1 06:00 13:003 4 06:00 13:003 5 14:00 22:00

Weekno    DayOfWeek     FromTime    ToTime
1         2             10:00       14:00
1         3             10:00       14:00
2         3             08:00       13:00
2         4             09:00       13:00
2         5             14:00       22:00
3         1             06:00       13:00
3         4             06:00       13:00
3         5             14:00       22:00

我想把它转换成一个看起来像这样的表格:<前>周开始1结束1开始2结束2开始3结束3开始4结束4开始5结束5开始6结束6开始7结束71 10:00 14:00 10:00 14:002 08:00 13:00 09:00 13:00 14:00 22:003 06:00 13:00 06:00 13:00 14:00 22:00
I want to convert this into a table that looks like this:
Week    Start1    End1    Start2    End2    Start3    End3    Start4    End4    Start5    End5    Start6    End6    Start7    End7
1                         10:00     14:00   10:00     14:00
2                                           08:00     13:00   09:00     13:00   14:00     22:00
3       06:00     13:00                                       06:00     13:00   14:00     22:00

有什么办法可以处理数据透视查询吗?请用一个例子来回答如何做.

CREATE TABLE #SO3241450 (
    Weekno int NOT NULL
    ,DayOfWeek int NOT NULL
    ,FromTime time NOT NULL
    ,ToTime time NOT NULL

INSERT INTO #SO3241450 VALUES

;WITH Base AS (
    SELECT Weekno, DayOfWeek, FromTime AS [Start], ToTime AS [End]

,norm AS (
