【问题描述】：
我有一张表，我将其显示为轴心。该表有一个category 和sub-category 列。我想为每个 category 添加一个总行，其中包含来自另一个表的初始值的运行计数，并添加来自特定 sub-category 的值。
这是帮助解释的完整工作示例。
设置：
CREATE TABLE dbo.rawdata
(
MyMonth [NVARCHAR](7) NOT NULL
, MyCategory [NVARCHAR](50) NOT NULL
, MySubCategory [NVARCHAR](50) NOT NULL
, MyCount [INT] NOT NULL
) ON [DEFAULT];
CREATE TABLE dbo.initial
(
MyCategory [NVARCHAR](50) NOT NULL
, MyStart [INT] NOT NULL
) ON [DEFAULT];
INSERT INTO dbo.rawdata (MyMonth, MyCategory, MySubCategory, MyCount)
VALUES
('2018-12', 'three', 'bravo', 7),
('2018-10', 'three', 'echo', 10),

期望的输出：
对于每个category，添加一个总计行。 第一个月的值将从dbo.initial表中获取起始值加上alphasub-category的值。下个月的值将采用上个月的值加上alpha sub-category。如果 category 没有 alpha sub-category 则使用 0。
所需的输出示例：
为了简洁起见，我只显示了几行和几个月，并且出于示例目的而显示了数学。

为什么不让这些列在同一行？

我不确定你的意思......
