cumulative-sum

问题 I am trying to write a SQL to calculate running total with in each group in the below input. Just wondering how can I do it using MySQL. I am aware of how to do it in regular SQL using analytic functions but not in MySQL. Could you share your thoughts on how to implement it. SQL Fiddle : http://sqlfiddle.com/#!9/59366d/19 SQL using window function : SELECT e.Id, SUM( e.Salary ) OVER( PARTITION BY e.Id ORDER BY e.Month ) AS cumm_sal FROM Employee e LEFT JOIN ( SELECT Id,MAX(Month) AS maxmonth

问题 I have a running total of another dynamically generated column (I7:I). I computed it using mmult() . The only problem with this is using indirect means the references break if I move data around in my sheet say by adding or removing rows above 7. If I use I7:I as my reference, it says the resulting array is too large. Is there a better way of doing this? =ArrayFormula( MMULT(TRANSPOSE((ROW(indirect("I7:I" & max(ArrayFormula(ROW(I6:I)*(I6:I <> "")))) )<=TRANSPOSE(ROW(indirect("I7:I" & max

问题 Okay, so I have a Google Sheet that I need to reduce a number down to a specific set of 4 numbers. Then count how many times those numbers occur. For example: The numbers it breaks down to: 1, 2, 3, 4 Disregard their individual values other than for the purpose of being broken down. Now take the number 17 . Count+Add 1, 2, 3, 4, 1, 2, 3 = 7 r1 Take number 12 Count+Add 1, 2, 3, 4, 1 = r1 The remainder is rounded DOWN So, basically, it breaks down Cell A1 into a count of how many sequences it

问题 >>> test.val.cumsum() 0 11 1 13 2 56 3 60 4 65 Name: val, dtype: int64 How do I get the original values from the cumulative sum? I will have to get [11,2,43,4,5] 回答1: You could use the diff() Series method (with fillna to replace the first value in the series): >>> s = pd.Series([11, 13, 56, 60, 65]) >>> s.diff().fillna(s) 0 11 1 2 2 43 3 4 4 5 dtype: float64 来源： https://stackoverflow.com/questions/26870116/get-original-values-from-cumulative-sum

问题 I have a data set spanning 2 years and is updated daily, created a dashboard to give a view of incidents by date group. I have created a parameter using date trunc for Day/Week/Month/Quarter/Year. This is in Tableau. I am trying to get the parameter to show a Week to date, Month to date and so on view. IE if on Weds 15th Dec I selected the weekly view, it would only show data for every week in the data set for Sat-Weds (My weeks go Sat-Fri) or the monthly view every month between 1st-15th

问题 This might be very simple... I have the below summary table in Power BI and need to build a Pareto Chart, what I'm looking for is a way to create columns "D" and "E"... Thanks in advance! The Count from column "B" is a measure I've created in PBI based on multiple filters. I've already tried some Calculate/Sum/Filter type of expressions with no luck. My raw data looks like Image #2... I have the measures to build the summary table with the exception of column "I" - Running % - (for which I

问题 I have an sql table trade with following data id| value 1| 0.1 2| 0.5 3| 0.9 4| 0.3 How do I make an SQL query so that i get the count of entries limited to total value of 0.8 ascending by id in php. For example:- COUNT id FROM trade WHERE SUM(value) > 0.8 by id ASC Result should come as 3 回答1: You need to do cumulative judgment,due to your mysql version didn't support window function so the solution will be a little hard to read,becuase you need to write subquery instead of window function.
