DATEDIFF with variable seed

I have the following table

enter image description here

The first column are transaction dates order by Date DESC. The second column is binary state for each transaction, could be either 0 or 1. The third column is the datediff of the minimum date compared to each date. the code that produces this table is something like that

DECLARE @date DATE 
SELECT @Date = MIN(CONVERT(DATE,Transaction_Created)) FROM #dates
SELECT      CONVERT(DATE,Transaction_Created)                       AS Date
    ,       MAX(Is_Deposit)                                         AS Is_Deposit
    ,       DATEDIFF(dd,@Date,CONVERT(DATE,Transaction_Created))    AS Datedif  

FROM        #DATES
GROUP BY    CONVERT(DATE,Transaction_Created)
order by 1 desc

My problem is that when is_Deposit=1 i need to reset my seed for DATEDIFF and the date of IS_Deposit =1 become my new MIN Date and so on for each IS_Deposit=1 i find in the table. For example from 2015-12-04 until 2015-12-16 everything is ok. But in line 746 2015-12-17 i would like this to be 1 again and not 13 as we have reached the next IS_Deposit=1 and we have to reset.

Resultset now:

Date    Is_Deposit  Datedif

Solution

You can do this with a couple of window functions. First a running total to build a cumulative sequence ID then pick out the minimum within each sequence:

With 
DatesSequence AS
(
SELECT Date,Is_Deposit
, SUM(Is_Deposit) OVER(ORDER BY Date DESC) AS Sequence
FROM #Dates
)
SELECT 
Date
,Is_Deposit
, DATEDIFF(day,
            MIN(Date) OVER (PARTITION BY Sequence),
            Date) + 1 AS DateDif
FROM DatesSequence
