sum

问题 I'm trying to display in a table (with data tables plugin) informations with sum from 3 tables using Left Join in sql query. I succeeded to edit server-side query and display correct datas with first jointure between two tables (t1=...budget & t2=..budget_changes) using the following query : $year=date('Y'); $sQuery = "SELECT SQL_CALC_FOUND_ROWS ".str_replace(" , ", " ", implode(", ", $aColumns)).", IFNULL(SUM(t2.change_amount),0) AS operation_changes, (t1.operation_BP+IFNULL(SUM(t2.change

问题 I'm currently working on some SUMIF formulae which will calculate certain values against specific conditions. All of the values to be calculated are decimalised but are based on 0.80 = 1.00. As an example if I have 1.25 and 1.60 to add together I would want the outcome to read 3.05 but currently, I would get an outcome of 2.85. Is it possible to amend the highest number a decimal can read before it converts to 1? Hope this makes sense. 回答1: try: =ARRAYFORMULA(SUM(QUOTIENT(D1:D3, 1))+ QUOTIENT

问题 Let's say I have a dataset contain visits in a hospital. My goal is to generate a variable that counts the number of unique patients the visitor has seen before at the date of the visit. I often work with group_by by dplyr but this seems a little tricky. I guess I would have to use group_by, n_distinct, and sum or some kind moving window command. The "goal" variable is what I need. visitor visitdt patient goal 125469 1/12/2018 15200 1 125469 1/19/2018 15200 1 125469 2/16/2018 15200 1 125469 2

问题 I have some records in my Database table. User passes the start and the end date and then expects an output. If a user passes the start and end date for same month then it should show only one record, but if the end date is extended one or more month then it should displays month wise record. For now I am able to collect total data while following this query. SELECT m.data_date_time , SUM(m.kwh) total_kwh , m.cust_id Customer_ID , m.msn FROM mdc_meters_data m WHERE m.data_date_time >= '2020

问题 I am trying to sum the total value of a column for a specific ID after multiple left joins. The below code gives me what I am looking for but across multiple rows, I need the value for T3.C_Amt and T4.E_Amt to be totaled. SELECT T1.ID, T2.Unique_ID, T3.C_Date, T3.C_Amount, T4.D_Date, T4.D_Amount FROM TABLE_1 T1 LEFT JOIN DATABASE1.TABLE_2 T2 ON T1.ID = T2.UNIQUE_ID LEFT JOIN DATABASE1.TABLE_3 T3 ON T2.Unique_ID = T3.Unique_ID AND T3.C_Date = '2019-04-11' LEFT JOIN DATABASE1.TABLE_4 T4 ON T2

问题 From a list of values I want to create a new list of values until they add up a value. I am new with Python but I believe it is best done with a while loop. L = [1,2,3,4,5,6,7,8,9] i = 0 s = 0 while i < len(L) and s + L[i] < 20: s += L[i] i += 1 回答1: numpy arrays make this simple import numpy as np arr = np.array(L) arr[arr.cumsum() <= 20].tolist() #[1, 2, 3, 4, 5] 回答2: Since you tagged Pandas: pd.Series(L, index=np.cumsum(L)).loc[:20].values Output: array([1, 2, 3, 4, 5], dtype=int64) 回答3:

问题 I have a sheet for every day in the month. At the end of every month, I need to sum the same cell across all tabs. The following works: =SUM(March31!L2,March30!L2,March29!L2,March28!L2,March26!L2,March25!L2,March24!L2) However, at the end of the month, the formula will be tremendous. Tried the following: =SUM(March31:March1!L2) Doesn't work. Is it even possible? 回答1: SUM(March31:March1!L2) that won't work, but you can use kind of a generator: ={" "; ARRAYFORMULA("=SUM("&TEXTJOIN(", ", 1, TEXT

问题 I´m new to Haskell. Let´s say I want to sum up the first n elements of a list with a generated function on my own. I don´t know how to do this with Haskell. I just know how to sum up a whole given list, e.g. sumList :: [Int] -> Int sumList [] = 0 sumList (x:xs) = x + sumList xs In order to sum up the first n elements of a list, for example take the first 5 numbers from [1..10] , which is 1+2+3+4+5 = 15 I thought I could do something like this: sumList :: Int -> [Int] -> Int sumList take [] =
