Sql server 返回指定日期列之间的行

我想要的结果是：

MatchDate   ColA    ColB    PossibleDate
01/01/2012  ABC     123     01/01/2012
01/01/2012  ABC     123     09/01/2012
01/01/2012  ABC     123     01/15/2013
09/01/2012  ABC     123     01/01/2012
09/01/2012  ABC     123     09/01/2012
09/01/2012  ABC     123     09/13/2012
09/01/2012  ABC     123     10/11/2012
09/01/2012  ABC     123     01/15/2013
01/15/2013  ABC     123     01/01/2012
01/15/2013  ABC     123     09/01/2012
01/15/2013  ABC     123     01/15/2013
01/15/2013  ABC     123     02/22/2013
08/15/2012  XYZ     777     08/15/2012
08/15/2012  XYZ     777     08/28/2012
08/15/2012  XYZ     777     10/11/2012
08/15/2012  XYZ     777     01/15/2013
01/15/2013  XYZ     777     01/15/2013
01/15/2013  XYZ     777     08/15/2012

它应该返回每个唯一的MatchDate、ColA和ColB列的行，以及介于MatchDate和PossibleDate之间的任何可能的日期

我添加了注释来解释为什么每一列都有效，为什么不有效：

MatchDate   ColA    ColB    PossibleDate
01/01/2012  ABC     123     NULL
09/01/2012  ABC     123     09/13/2012
09/01/2012  ABC     123     10/11/2012
01/15/2013  ABC     123     02/22/2013
08/15/2012  XYZ     777     08/28/2012
08/15/2012  XYZ     777     10/11/2012
01/15/2013  XYZ     777     NULL

提前谢谢…希望不要太混乱。

不确定我是否理解所有内容，请尝试一下

除了开玩笑和阿斯匹林，我想你必须更清楚地解释你的搜索协议才能得到任何帮助，否则我怀疑你可能会冒险把问题结束……我已经试过几次来解开你的问题，但我只是没有达到目的……抱歉：对不起，我试图解释为什么每一列都是有效的。基本上，对于给定的组，我需要两个特定日期之间的所有行。问题是它需要比较的日期可能在下一行。呃……任何时候你开始查看SQL数据集，然后讨论下一行可能是什么，你只是让编写查询变得非常不愉快。希望其他人能帮助你，因为我不够聪明，无法从你列出的结果中推断出你的一般规则。谢谢你的努力，对不起，我帮不了你。这很有效。很抱歉，范围太窄，但我相信其他人可以使用此功能。
