The top right cell (Natwest) is a list from a range using data validation.
The Opening Balance 1,000.00 is sourced from another sheet using a lookup formula.
Using simple if statements, the cumulative balance is then produced - according to the Amount column and whether the Natwest account occurs in the Dr(+) or Cr (-) column
i.e. =if(B4=$D$1,D3+A4,if(C4=$D$1,D3-A4,D3)) and copied down.
Natwest
Amount Dr Cr Balance
1,000.00
100.00 Natwest Account 1 1,100.00
200.00 Account 2 Natwest 900.00
400.00 Natwest Account 1 1,300.00
It works fine, except that when a new row is inserted, the if statement formula is not copied into the new row.
I am looking for an arrayformula solution (or other formula inside the cell solution), so that the Cumulative Balance still works, but doesn't need to be copied into column D new row - when a new row(s) are inserted.
(I don't mind the Natwest (drop down from the list) or the Opening Balance 1,000.00 to be moved elsewhere if required for a solution.)
Thanks for your help.
Something adding up in between the same range of the arrayformula is always going to be tricky with circular dependency. I suggest to get the initial value and add it the SUMIF of second column and substract the SUMIF of second column up to each value. With BYROW you can do it like this:
=BYROW(A4:A,LAMBDA(each,SUMIF(INDIRECT("B4:B"&ROW(each)),D1,A4:each)-SUMIF(INDIRECT("C4:C"&ROW(each)),D1,A4:each)+D3))
Alternate solution:
You can use this custom function from AppScript for automatically calculating cumulative balance
Code:
function customFunction(startnum, key, range) {
var res = [];
var current = startnum;
range.forEach((x) => {
res.push(x.map((y, index) => {
return y == key && index == 1 ? current = (current + x[0]) : (y == key && index == 2 ? current = (current - x[0]) : null)
}).filter(c => c))
})
return res;
}
Custom Function Parameters:
=customFunction(startnum, key, range)
startnum = opening balance
key = Account name
range = cell range
Sample output:
=customFunction(D3,D1,A4:C)
I have a spreadsheet with criteria, a start and end date, and a value. The goal is to find the lowest value for each unique criteria and start date without overlapping dates (exclusive of end date). I made a pivot table to make it easier for myself but I know there is probably a way to highlight all valid rows that meet the above requirements with some formula or conditional formatting.
I have attached a google drive link where the spreadsheet can be found here and I have some images of the sheet as well. I know that it might be possible with conditional formatting but I just don't know how to combine everything I want it to do in a single formula.
Example below:
Row 2 is a valid entry because it has the lowest value for Item 1 starting on 03-15-2021, same with row 9.
Row 5 is valid because the start date does not fall within the date range of row 2 (exclusive of end date)
Row 7 is not valid because the start date is between the start and end date of row 6
You may add a bounded script to your project. Then you can call it either with a picture/drawing that has the function assigned (button-like), or adding a menu to Google Sheets.
From what you said in the question and the comments, this seems to do what you are trying. Notice that this requires the V8 runtime (which should be the default).

Algorithm rundown
We get the sheet that we have the data in. In this case we do it by name (remember to change it if it's not the default Sheet1)
We read the data and transform it in a more an array of objects, which for this case makes it easier to manage
We sort the data. This is similar to the transpose you made but in the code. It also forces a priority order and groups it by criteria
Iterate the rows, keeping only the valid:
We keep a list of all the valid ones (valid) and one for the current criteria only (currentValid) because we only have to check data collisions with the ones in the same criteria.
The first iteration will always enter the if block (because currentCriteria is undefined).
When changing criteria, we dump all the rows in currentValid into valid. We do the same after the loop with the last criteria
When changing criteria, the CurrentValid is an array with the current row as an element because the first row will always be valid (because of sorting)
For the other rows, we check if the starting date is between the starting and ending date of any of the valid rows for that criteria. If it's not, add it to this criteria's valid rows
We remove all the current "Valid" in the validity row and fill it out with the valids
The cornerstone of the algorithm is actually sorting the data. It allows us to not have to search for the best row, as it's always the next one. It also ensures things like that the first row of a criteria is always valid.

I'm trying to make a formula that can recognize in Column A the name Brooke B for instance here, from there I'd like to SUM the values listed in Column I Cash Discounts for that specific user.
(Yes this user has no Cash Discounts, thus column I states "Non-Cash Payment").
There's about 80 users total here, so I'd prefer to automate the name recognition in Column A.
Sheet: https://docs.google.com/spreadsheets/d/1xzzHT7VjG24UJ4ZXaiZWsfzroTpn7jCJLexuTOf6SQs/edit?usp=sharing
Desired Results listed in Cash Discounts sheet, listed per user in column C.
You are trying to calculate the total amount of the Cash Discount per person given to people in a list. You have data that has been exported from a POS system to which that you have added a formula to calculate the amout of the discount on a line by line basis. You have speculated whether the discount totals could be calculated using SUMIFS formulae.
In my view, the layout of the spreadsheet and the format of the POS report do not lend themselves to isolating discrete data elements though Google sheets functions (though, no doubt, someone with greater skills than I will disprove this theory). Column A, containing names, also includes sub-groupings (and their sub-totals) as well as transaction dates. There are 83 unique persons and over 31,900 transaction lines.
This answer is a script-based solution which updates a sheet with the names and values of the discount totals. The elapsed execution time is #11 seconds.

Report Sheet - extract
Not everyone wants a script solution to their problem. This answer seeks to supply a repeatable solution using common garden-variety formula/functions.
As noted elsewhere, the layout of the spreadsheet does not lend itself to a quick/simple solution, but it IS possible to break down the data to compile a non-script answer. Though it may "seem" as though the following formula are less than "simple, when taken one-at-a-time they are logical, very easy to create, and very easy to verify successful outcomes.
Note: It is important to know at the outset that the first row of data = row#3, and the last row of data = row#31916.
Step#1 - get Text values from ColumnA
Enter this formula in Cell J3, and copy to row 31916
=if(isdate(A3),"",A3):
evaluates Column A, if the content is a date, returns blank, otherwise, returns the context
Taking Customer "AJ" as an example, the content at this point includes:
AJ
10% BuildingDiscount
10% BuildingDiscount Total:
Northwestern 10%
Northwestern 10% Total:
AJ Total:
Step#2 - ignore the values that contain "10%" (this removes both headings and sub-subtotals
Enter this formula in Cell K3 and copy to row 31916
=iferror(if(search("10%",J3)>0,"",J3),J3): searches for "10%" in Column J. Returns all values except those that containing "10%".
Taking Customer "AJ" as an example, the content at this point includes:
AJ
AJ Total:
**Step#3 - ignore the values that contain the word "Total"
Enter this formula in Cell L3 and copy to row 31916.
=iferror(if(search("total",K3)>0,"",K3),K3)
Taking Customer "AJ" as an example, the content at this point includes:
AJ
Results after Step#3
You might wonder, "couldn't this be done in a single formula?" and/or "an array formula would be more efficent". Both those thoughts are true, but we're looking at simple and easy, and a single formula is NOT simple (as shown below); and given that, an array formula is out-of-the-question unless/until an expert can wave a magic wand over the data.
FWIW - Combining Steps#1, 2 & 3
each of the Steps#1, 2 and 3 build on each other. So it is possible to create a single formula that combines these steps.
enter this formula in Cell J3, and copy dow to row #31916.
=iferror(if(search("total",iferror(if(search("10%",if(isdate(A3),"",A3))>0,"",if(isdate(A3),"",A3)),if(isdate(A3),"",A3)))>0,"",iferror(if(search("10%",if(isdate(A3),"",A3))>0,"",if(isdate(A3),"",A3)),if(isdate(A3),"",A3))),iferror(if(search("10%",if(isdate(A3),"",A3))>0,"",if(isdate(A3),"",A3)),if(isdate(A3),"",A3)))
As the image showed, step#3 concludes with mainly empty cells in Column L; the only populated cell is the first instance of the customer name at the start of their transactions - such as "Alec" in this example. However (props to #Rubén) it is possible to populate the blank transaction Cells in Column L. An arrayformula to find the previous non-empty cell in another column on Webapps explains how.
Step#4 - Create a customer name for each transaction row.
Enter this formula in Cell M3, it will automatically populate the cells to row#31916
=ArrayFormula(vlookup(ROW(3:31916),{IF(LEN(L3:L31916)>0,ROW(3:31916),""),L3:L31916},2))
Step#5 - Get the discount amount for each transaction value
The discount values are already displayed in Column I. They are interspersed with text values, so the formula for tests if this is a total line by testing the value in Column D; only if there is a vale (Product item) does the formula then test of there is a value in column I.
Enter this formula in Cell N3, it will automatically populate the cells to row#31916
=ArrayFormula(if(len(D3:D31914)>0,if(ISNUMBER(I3:I31916),I3:I31916,0),""))
Screenshot after step#5
Reporting by Query
Reporting is done via queries. These can go anywhere, but it is probably more convenient to put it on a separate sheet.
Step#6.1 - query the results to create report showing total by ALL customers
=query(Discounts_analysis!$M$2:$N$31916,"select M, sum(N) where N is not null group by M label M 'Customer', sum(N) 'Total Discount' ",1)
Step#6.2 - query the results to create report showing total by customer where the customer received a discount
=query(Discounts_analysis!$M$2:$N$31916,"select M, sum(N) where N >0 group by M label M 'Customer', sum(N) 'Total Discount' ",1)
Step#6.3 - query the results to create report showing customers with no discount
- `=query(query(Discounts_analysis!$M$2:$N$31916,"select M, sum(N) where N is not null group by M label M 'Customer', sum(N) 'Total Discount' ",1),"select Col1 where Col2=0")`
Queries screenshot
I'm trying to return a count of records from a database with today's date, using entity framework. I think my query is ok, if you take a look at the screenshot record 2 is the only item out of the 3 with todays date, which is correct.
How can i return a count. Currently its returning a bool value
Thank you
Dim today = DateTime.Today.Date
Dim todaysBuild = retrieveOrders.[Select](Function(build) build.TimeAndDate >= today).ToList()
EDIT:
Dim todaysBuild = retrieveOrders.Where(Function(build) build.TimeAndDate >= today).ToList()
The variable todaysBuild is a list. You need the count (Integer) of that list so add the .Count at the end of your code.
Dim todaysBuild = retrieveOrders.[WHERE](Function(build) build.TimeAndDate >= today).ToList.Count
I have a bunch of records that are sorted RANDOMLY, like so:
var entries = DataContext.Entries.OrderBy(e => Random());
The Random function returns a randomly-generated GUID, thereby ordering the records in a random manner. Now my problem is paging. In MVC, I have a List action for the Entry controller that lists the entries:
public class EntryController : Controller
{
public ActionResult List(int page)
{
int pageSize = 10;
var entries = DataContext.Entries.OrderBy(e => Random()).Skip((page - 1) * pageSize).Take(pageSize);
ViewData["entries"] = entries;
return View();
}
}
My problem here is that whenever I go from one page to another page, the entries are REARRANGED ANEW. So when I go to page 1 (step 1), then go to page 2 (step 2), then back to page 1 (step 3), the entries that were shown in the step 1 are different from those shown in step 3. I absolutely need to have the records arranged randomly the first time around, but not in the subsequent look ups.
Any ideas on how best to address this problem?
Because each time you invoke the action the randomness occurs all over again to the whole records before paging, what you need to do is:
Order the records randomly as you want it.
Cache the result.
Fetch the cache every time the action is invoked while applying paging.
public ActionResult List(int page)
{
var dataSource = CacheContext["RandomRecords"];
if(dataSource == null){
dataSource = DataContext.Entries.OrderBy(e => Random());
}
int pageSize = 10;
var entries = dataSource.Skip((page - 1) * pageSize).Take(pageSize);
ViewData["entries"] = entries;
return View();
}
Add a column named sortOrder, being an int.
Do not forget to add a non-unique index on it or sorting on it will be suboptimal.
Put a number there, increased from record to record, not in the same order than your id or an order that would sort the records alphabetically.
Then
dataSource = DataContext.Entries.OrderBy(e => e.sortOrder);
Guids will be slower to sort on, but you can alternatively use a guid column for the task. Every now and then (once per night), you can loop through all records to put new values in the sortOrder column so people will not recognize the order.
You can add following SQL code to get products, you only need to generate some random number and store it into the session or cache and get product again..
DECLARE #NumberOfProductsInDatabase INT
DECLARE #RandomNumber VARCHAR(10)
SET #NumberOfProductsInDatabase = (SELECT COUNT(*) FROM Product)
SET #RandomNumber = '45'
SELECT CAST(100000 * SQRT(EXP(COS(p.SellerId + #RandomNumber))) AS INT) % #NumberOfProductsInDatabase AS RandomProductNr,
p.Id,p.Name,pv.Price,pv.SalePrice
FROM Product p,ProductVariant pv
WHERE pv.ProductId = p.Id
ORDER BY RandomProductNr
