不确定我是否能够正确描述问题的标题，但我还没有在T-Sql中做过任何复杂的事情。这就是我想要实现的目标。
在几次查询和表构建之后，我在临时表中得到了数据（下面），这可能会成为一个永久表。 我需要帮助的部分是，需要根据以下数据创建另一个表来报告部分销售。
Table 1
LOC# ITEM sale_total FiscalYear FiscalPrd TYPE O_R DESC LFT_EXP METHOD PRD_MO AG_PCNT PLAN_ID YEARS STATUS
33 17879 12203.57 2017 3 A O Plan A L W 120 100.00 6 10 N
33 17903 579.97 2017 3 A O Plan A L W 120 100.00 6 10 N
33 18870 799.60 2017 3 A O Plan A L W 120 100.00 6 10 N
33 19739 319.95 2017 3 A B Plan C E F 36 100.00 8 3 N
33 21585 559.96 2017 3 B O Plan B E N 0 100.00 10 0 N
上表中sale_total的百分比需要根据下表进行分配（如果事情更简单，我还可以在上表中包含YR01-YR10列）。
Table 2
PLAN_ID EFDATE MONTHS METHOD EPERCENT YR01 YR02 YR03 YR04 YR05 YR06 YR07 YR08 YR09 YR10

因此，对于LOC＃33和项目18870，我的最终结果如下所示:(因此计算基于计划。对于此具体示例，项目18870属于计划6（表1）。表2具有分布所有计划。我们可以看到它分布在120个月以上，YR01-YR10的年度百分比分布。现在从表1的788.60的18870的销售数字，第1年的分布数学是（799.60 x 0.4）/ 12 = 26.65同样的方法可以追溯到本计划的第10年和计划8的第3年。对于10年计划，它将创建120个输入记录。每个项目每个月1个，位置）
LOC# ITEM FiscalYear FiscalPrd SALES
33 18870 2017 4 26.65
33 18870 2017 5 26.85
33 18870 2017 6 26.85
.............................................

.............................................
.............................................
33 18870 2027 2 0.67
33 18870 2027 3 0.67
它将按照表2中planID 6规定的百分比分配120个月以上的收入。对于planID 8，它将在36个月内进行相同的数学计算。 百分比可以随时间变化，用户将管理计划。还有其他位置，第一个表将包括当前会计期间的所有位置和所有项目（表2中显示的最大值为3）。我创建了一个状态列，以便在处理完数据后进行标记。
当下一个会计期间销售时，程序将更新上述结果集销售数字以包括新销售。它将每月运行一次以产生上述结果。
当我达到这一点并且不确定如何从这里接近时，会非常欣赏某些方向。
非常感谢。
@ZLK我在临时表中保存了第一次运行，然后添加了以下行
(33, 17879, 10000.00, 2017, 4, 6, 10),
(33, 17903, 500.00, 2017, 4, 6, 10),
(33, 18870, 800.00, 2017, 4, 6, 10),
(33, 19739, 300.00, 2017, 4, 8, 3),
(33, 21585, 500.00, 2017, 4, 10, 0);
这是保存第一组项目，在财政期间4中具有不同销售编号的位置。第一组被插入到表#finalDist中，第二组使用以下查询来插入和更新。
begin tran
if exists (select * FROM #finalDist AGE
INNER JOIN #dist PrdAg on PrdAg.Loc = AGE.Loc
and PrdAg.Item = AGE.Item
and PrdAg.FiscalYear = AGE.FiscalYear
and PrdAg.FiscalPrd = AGE.FiscalPrd)
begin
UPDATE AGE
SET AGE.SALES = AGE.SALES + PrdAg.SALES
FROM #finalDist AGE
INNER JOIN #dist PrdAg on PrdAg.Loc = AGE.Loc
and PrdAg.Item = AGE.Item
and PrdAg.FiscalYear = AGE.FiscalYear
and PrdAg.FiscalPrd = AGE.FiscalPrd
end
else
begin
INSERT INTO #finalDist (Loc, Item, FiscalYear, FiscalPrd, SALES)
SELECT Loc, Item, FiscalYear, FiscalPrd, SALES from #dist PrdAg

and PrdAg.Item = AGE.Item
and PrdAg.FiscalYear = AGE.FISCALYear
and PrdAg.FiscalPrd = AGE.FiscalPrd)
end
commit tran
我意识到我无法做其他事情，因为我需要同时进行插入和更新。它将更新除财政期间3之外的所有内容，然后它将为此案例插入四行

基本上你想得到一个数字列表（这里最多120个，但如果超过10年，你需要更多）并交叉加入你的桌子。然后将表2中的值取消，并将它们链接到数字表中（按年份分组）。
修改
