---- ------ ----- ----- --- ------
CCP1 1 1 2015 5 25 -- 5 * 5 (here 5 is the baseline)
CCP1 2 1 2015 6 30 -- 6 * 5 (here 5 is the baseline)
CCP1 3 1 2015 7 35 -- 7 * 5 (here 5 is the baseline)
CCP1 4 2 2015 4 360 -- 90 * 4(25+30+35 = 90 is the basline)
CCP1 5 2 2015 2 180 -- 90 * 2(25+30+35 = 90 is the basline)
CCP1 6 2 2015 2 180 -- 90 * 2(25+30+35 = 90 is the basline)
...
next quarter baseline will be (720)
Explantion
基线表具有每个CCP的单一基线值。
基准值应适用于每个CCP的第一季度，并且对于下一季度，上一季度的总和值将是basleine。
是的我可以使用While循环或光标来做到这一点，但我正在寻找更好的方法到目前为止我尝试过这样的事情。但是没有说出我在这里失踪的东西。

我认为如果你在递归锚中添加一个行号，那么将cte中的连接限制为每季度只有3行中的一行，就可以达到你想要的结果：
publish_pages这会产生：
