垂直到水平查看SQL

Question

我有以下表格：

ID GroupCode  oDate  oTime  oValue 
1  A    2014-06-01 00:00:00 200 
2  A    2014-06-01 01:00:00 300 
3  A    2014-06-01 02:00:00 400 
FF. until oTime reach 23:00:00 then it will create a new date. which is 2014-06-02 
25 B    2014-06-01 00:00:00 600 
26 B    2014-06-01 01:00:00 700 
27 B    2014-06-01 02:00:00 725 
FF. until oTime reach 23:00:00 then it will create a new date. which is 2014-06-02 

我的问题是，如何才能让它在水平SQL视图？我想得到以下结果：

GroupCode1 oDate1  oTime1  oValue1  GroupCode2  oDate2  oTime2 oValue2 
A   2014-06-01 00:00:00 200   B    2014-06-01 00:00:00 600 
A   2014-06-01 01:00:00 300   B    2014-06-01 01:00:00 700 
A   2014-06-01 02:00:00 400   B    2014-06-01 02:00:00 725 

有没有人知道如何做到这一点？
谢谢。万分感激。

如果只有3组码A，B，C以及每个组的代码有23行指定日期，那么你可以写为：

select GroupCode1, oDate1,oTime1,oValue1,GroupCode2, oDate2,oTime2,oValue2 
     ,GroupCode3, oDate3,oTime3,oValue3 
from 
(select GroupCode as GroupCode1, 
     oDate as oDate1, 
     oTime as oTime1, 
     oValue as oValue1 
from table1 
where GroupCode = 'A')T1 full join 
(select GroupCode as GroupCode2, 
     oDate as oDate2, 
     oTime as oTime2, 
     oValue as oValue2 
from table1 
where GroupCode = 'B')T2 on T1.oDate1 = T2.oDate2 and T1.oTime1 = T2.oTime2 
full join 
(select GroupCode as GroupCode3, 
     oDate as oDate3, 
     oTime as oTime3, 
     oValue as oValue3 
from table1 
where GroupCode = 'C')T3 on T1.oDate1 = T3.oDate3 and T1.oTime1 = T3.oTime3
