SQL中连续重复列数据的其他列值的总和

我只需要为连续列的数据添加持续时间值。假设在此表中执行数据3次，每次执行3次，2次和1次。所以我想按照状态列的连续性添加持续时间列的数据3次。 我在这里需要执行的只显示1次而不是连续3次，并且再次显示第2次执行的相同规则，显示2次，因此它还将显示1次持续时间列值的累积和。因此，每个迭代行将带有持续时间值的总和并显示为单行

CREATE TABLE Tools
    ([ID] int, [StartDatetime] varchar, [EndDatetime] varchar, [duration] int,  [durationDatetime] varchar, [state] varchar(50), [stateCode] int)
;

INSERT INTO Tools
    ([ID], [StartDatetime], [EndDatetime], [duration],  [durationDatetime], [state], [stateCode])
VALUES

(1367, '2018-03-15 10:02:52', '2018-03-15T10:19:32.7000000', 100, '1900-01-01T00:16:39.7800000', 'Execute', 6),

您可以尝试一下，我也遇到了这种情况，并使用此代码段找到了解决方案。

  select grp, value, min(id), max(id), count(*) as cnt
    from (select t.*, (row_number() over (order by id) - row_number() over partition by value order by id)
         ) as grp
    from table t
   ) t
  group by grp, value;

我已经添加了一个KID列（标识），因为Sean Lange已经指出您需要订单。

CREATE TABLE Tools
(
    [KID] int identity,
    [ID] int, 
    [StartDatetime] varchar(50), 
    [EndDatetime] varchar(50), 
    [duration] int,  
    [durationDatetime] varchar(50), 
    [state] varchar(50), 
    [stateCode] int
);
GO

INSERT INTO Tools ([ID], [StartDatetime], [EndDatetime], [duration],  [durationDatetime], [state], [stateCode]) VALUES

(1367, '2018-03-15 10:02:52', '2018-03-15T10:19:32.7000000', 900, '1900-01-01T00:16:39.7800000', 'Execute', 6),
