这个语句应该怎么写?

Question

tableAId  Type Time7
1   0    2013-01-03 00:00:18
2   1    2013-01-05 01:20:07
3   2    2013-01-08 23:08:02
4   2    2013-01-08 01:07:02
tableC
TypeId  TypeName
0       AAA
1       BBB
2       CCCtableA的Type字段对应tableC的TypeId字段我想统计出这样一个效果时段  00:00:01-01:00:00   01:00:01-02:00:00  ... 23:00:01-24:00:00  合计
AAA     1                    0                        0             1
BBB     0                    1                        0             1
CCC     0                    1                        1             2
合计     1                    2                        1             4
    
其中时段这一行有24列,分别对应24个小时请问这个语句应该怎么写?

USE test

drop table tableA
