数据的动态插入
表A 
其中RouteCode,DriveDate是主键 

RouteCode RouteName DriveDate 11 12 13       14    15
3 花 2007-10-05 00:00:00 Null Null Null    null null
4 草 2007-10-05 00:00:00 Null Null Null null null
5 树 2007-10-05 00:00:00 Null Null Null null null
3 木 2007-10-06 00:00:00 Null Null Null null null
4 石头 2007-10-06 00:00:00 Null Null Null null null
表B 
其中RoutCode,DriveDate主键 并且B表还要不断的加数据,ShapeCode有可能加入14的,15的
RouteCode DriveDate ShapeCode Amount 
3 2007-10-05 00:00:00 11 65 
4 2007-10-05 00:00:00 11 5 
5 2007-10-05 00:00:00 11 15 
3 2007-10-05 00:00:00 12 65 
4 2007-10-05 00:00:00 12 7 
5 2007-10-05 00:00:00 12 13 
3 2007-10-05 00:00:00 13 10 
4 2007-10-05 00:00:00 13 5 
5 2007-10-05 00:00:00 13 15 
3 2007-10-06 00:00:00 11 10 
4 2007-10-06 00:00:00 11 11 
把上面相同RouteCode,DriveDate的Amount差入A表中 
变成如下所示 
RouteCode      RouteName    DriveDate      11    12    13 14 15
3         花        2007-10-05    65 65    10 null null
4         草     2007-10-05     5   7     5 null null
5         树    2007-10-05    15    13    15 null null
3         木    2007-10-06    10   Null   Null null null
4        石头       2007-10-06     11   Null    Null null null
我的不清楚RouteCode,RouteName,DriveDate怎么对应。在线等待,上午有些不明白。
还有怎么合并相同日期和RouteCode的同时进行行列转换和Amount数据的填充,一直在线
