快跑蜗牛哥 2008-01-24 10:53:53

已知表：XingShiLiCheng
资料名称 类型 长度
CarMark varchar 20
topDate datetime 8
CarLiCheng float 8
eg:表中数据：

CarMark topDate CarLiCheng
S05261 2007/12/29 10:26:24 3081.6
S05261 2007/12/29 11:20:20 3181.6
S05261 2007/12/29 15:26:24 3181.6
S05261 2007/12/29 18:26:24 3181.6
S05261 2007/12/29 20:26:24 3281.8
S22126 2007/12/29 10:26:24 2081.6
S22126 2007/12/29 13:26:24 2081.6
S22126 2007/12/29 15:26:24 2081.6
另有获得的值top1=2007/01/29 02:21:29、tup2=2008/01/30 02:21:29
求一SQL语句满足当top1<=topDate<=tup2时，可得到
CarMark topDate1 topDate2 CarLiCheng1 CarLiCheng2 CarLi
S05261 2007/12/29 10:26:24 2007/12/29 20:26:24 3081.6 3281.8 200.2
