如何使兩列到行和剩餘的，因爲它是在SQL Server 2008中

Question

我的表由以下數據

ID | ST_NAME| ST_DATE_TIME| ST_SPEED 
-----------------------------------------------  
1 |E11|July, 14 2013 01:00:00+0000| 106 
3 |E10 |July, 14 2013 02:00:00+0000| 124 
4 |E10 |July, 14 2013 03:00:00+0000| 117 
5 |E10 |July, 15 2013 01:00:00+0000| 124 
6 |E10 |July, 15 2013 02:00:00+0000| 106 
7 |E10 |July, 15 2013 03:00:00+0000| 106 

我需要以下結果

ST_Name| 1:00| 2:00| 3:00| ... |24:00 
E11|106| Null| Null|.... |Null 
E10|124|..... 

使每個小時st_name作爲的作爲一列。每個st_name作爲速度的總和作爲

行

這是我試圖

SELECT 
    '01:00' as "01:00", '02:00' as "02:00", '03:00' as "03:00" .... '24:00' as  "24:00" 
FROM 
    (SELECT 
     ST_SPEED, substring(CONVERT(VARCHAR, ST_DATE_TIME, 114), 1, 5) AS p 
FROM t_data) AS s 
PIVOT 
    (SUM(ST_SPEED) FOR p in ("01:00", "02:00", "03:00")) AS PivotTable 

但顯示出一些其他的結果，請幫助...

嘗試這一個 -

DECLARE @t TABLE 
(
    ID INT IDENTITY(1,1) PRIMARY KEY, 
    ST_NAME CHAR(3), 
    ST_DATE_TIME DATETIME, 
    ST_SPEED TINYINT 
) 

INSERT INTO @t (ST_NAME, ST_DATE_TIME, ST_SPEED) 
VALUES 
    ('E11', '20130714 01:00:00', 106), 
    ('E10', '20130714 02:00:00', 124), 
    ('E10', '20130714 03:00:00', 117), 
    ('E10', '20130715 01:00:00', 124), 
    ('E10', '20130715 02:00:00', 106), 
    ('E10', '20130715 03:00:00', 106) 

SELECT * 
FROM (
    SELECT ST_NAME, ST_SPEED, CONVERT(VARCHAR(5), ST_DATE_TIME, 8) AS p 
    FROM @t 
) s 
PIVOT 
(
    SUM(ST_SPEED) FOR p IN (
     [01:00], [02:00], [03:00], 
     [04:00], [05:00], [06:00], 
     [07:00], [08:00], [09:00], 
     [10:00], [11:00], [12:00], 
     [13:00], [14:00], [15:00], 
     [16:00], [17:00], [18:00], 
     [19:00], [20:00], [21:00], 
     [22:00], [23:00], [24:00]) 
) p 

輸出 -

ST_NAME 01:00  02:00  03:00  04:00  05:00  06:00  07:00  08:00  09:00  10:00  11:00  12:00  13:00  14:00  15:00  16:00  17:00  18:00  19:00  20:00  21:00  22:00  23:00  24:00
