这个语句应该怎么写?

abz87870 2013-01-23 11:57:51

tableA

Id 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 CCC

tableA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?

引用 3 楼 abz87870 的回复: 有谁能给我写一下具体的sql语句吗? 人家不给你发链接了嘛，自己学一下，下次就不用问人了。

最好是能给个具体的sql语句,这样学起来更加方便一点

谢谢你写的语句,我想请问一下,假如要加个时间搜索条件的话,应该放在哪里?
