我有一个独特的问题，我根本无法解决这个问题。
所以我在SQL Server 2005中，我可以使用以下数据：
我需要分配6个财政年度和剩余时间的月份
例如：
FISCAL_YEAR_START_MONTH = 7
COUNT_START_MONTH = 9
TOTAL_MONTHS = 36
YEAR1_MONTHS = 4
YEAR2_MONTHS = 12
YEAR3_MONTHS = 12
YEAR4_MONTHS = 8
应输出
YEAR1_MONTHS YEAR2_MONTHS YEAR3_MONTHS YEAR4_MONTHS YEAR5_MONTHS YEAR6_MONTHS LEFTOVER
------------ ------------ ------------ ------------ ------------ ------------ ----------
10 12 12 2 0 0 0
我只是无法在sql中解决这个问题。很容易看出几个月应该作为一个人在个案中分配，但我无法将其转化为算法。
我尝试计算每年的日期，并保持我剩下几个月的运行次数，但都没有解决我的问题。
任何解决方案，即使是上述示例中的特定解决方案（但理想情况下是一般解决方案）也会非常有用！
编辑：修正了翻转问题，好像我收到了错误的数据
EDIT2：另一个例子，一个简单的例子：
FISCAL_YEAR_START_MONTH = 7
COUNT_START_MONTH = 5
TOTAL_MONTHS = 14
YEAR1_MONTHS = 8
YEAR2_MONTHS = 6
应输出
YEAR1_MONTHS YEAR2_MONTHS YEAR3_MONTHS YEAR4_MONTHS YEAR5_MONTHS YEAR6_MONTHS LEFTOVER
------------ ------------ ------------ ------------ ------------ ------------ ----------
