this might look simple.. but dk how to do it
this is the information:
So.. i got the Cumulative Total using this function:
CumulativeTotal = CALCULATE(
SUM(vnxcritical[Used Space GB]),
FILTER(ALL(Datesonly[Date]),
Datesonly[Date] <= MAX(Datesonly[Date])))
But what i need is to get the differences between the dates, in the first date and the second the difference will be of 210. I need to get another column with that information. know the formula to do that?
ok..
So.. i used this:
IncrmentalValueTEST =
VAR CurrDate = MAX(vnxcritical[Date])
VAR PrevDate = CALCULATE(LASTDATE(vnxcritical[Date]), vnxcritical[Date] < CurrDate)
RETURN SUM(vnxcritical[Used Space GB]) -
CALCULATE(SUM(vnxcritical[Used Space GB]), vnxcritical[Date] = PrevDate)
and this is the result:
Ok, so this is is my data table:
You can see all the dates that i have for now, this is a capacity report for diferents EMC Storage Arrays, for diferentes Pools. The idea would be to have the knolwdge to review the incremental space used in a determinated portion of time.
allready tried another idea to get this, but the result was the same.. i used this:
Diferencia =
Var Day = MAX(Datesonly[Month])
Var Month = MAX(Datesonly[Year])
RETURN
SUM('Used Space'[used_mb])
- CALCULATE(
SUM('Used Space'[used_mb])
,FILTER(ALL(Datesonly[Date]),Datesonly[Date] <= Max(Datesonly[Date])))
But the return is the same.. "47753152401"
i'm using graphical filters, and other things to get a minimal view, because there are only 5 weekly reports and the sql database got more than 150.000 rows.
and this is the relation that i made with a only a table full of "dates" in order to invoke the function in a better way, but the result is the same..
Try something along these lines:
IncrmentalValue =
VAR CurrDate = MAX(Datesonly[Date])
VAR PrevDate = CALCULATE(LASTDATE(Datesonly[Date]), Datesonly[Date] < CurrDate)
RETURN SUM(vnxcritical[Used Space GB]) -
CALCULATE(SUM(vnxcritical[Used Space GB]), Datesonly[Date] = PrevDate)
First, calculate the current date and then find the previous date by taking the last date that occurred before it. Then take the difference between the current value and the previous value.

I have two datasets:
Dataset 1 - Records the details of a store visit. Merchandiser name, location, date & a relation to SKU (Dataset 2)
Dataset 2 - This is the SKU data, where the stock levels for each sku are input as a new record, each associated to a visit from Dataset 1.
I have two issues:
I want to combine this data into a single table. I want to show each SKU record, with additional columns for the visit information (such as the location & date). How do I do this.
How do I combine this data for use elsewhere, such as google data studio. Essentially I want to be able to see an SKU's stock-level's history, or the date it was last updated.
You need to create Calculated Data Source. You can refer this sample.
On a high Level
Add data source in Appmaker.
Select Calculated, provide Name and Create the data source.
Once your Calculated Model is in place. Add fields as per need basis. e.g. If you want to store Sum of two fields, create one Integer field in Calculated Model. Here's how your calculated data model will look like.
Now go to Second Tab which is "Datasources". Click on the Data Model name there. You should see an option to write server side script.
Here you should write your logic for combining your data sources. I can provide you one sample to achieve this.
//server script
var calculatedModelRecords = [];
var recordsByStatus = {};
var allRecord = app.models.Request.newQuery().run(); //your existing data source.
for (var i = 0; i < allRecord.length; i++) {
var record = allRecord[i];
var draftRecord = app.models.TAT.newRecord(); //new data source
draftRecord.CreatedOn = record.CreatedOn;
draftRecord.DocumentName = record.DocumentName;
draftRecord.DueDate = record.DueDate;
draftRecord.DaysPerStage = record.DaysPerStage;
draftRecord.Status = record.Status;
calculatedModelRecords.push(draftRecord);
}
return calculatedModelRecords;
Im trying to show the total number of people in each geography when they hover over using crossfilter, but my current code is only showing the total of all geographies. So what is the equivalent in crossfilter to the sql query: SELECT COUNT(*) GROUP BY dma
This is my code so far
//geography that is being hovered over, getting dma name and removing everything that is after the comma
sel_geog = layer.feature.properties.dma_1;
sel_geog = sel_geog.split(",")[0];
console.log(sel_geog);
//crossfilter to get total number of people of each geography
var dmaDim = voter_data.dimension(function(d) {return d.dma == sel_geog}),
dma_grp = dmaDim.groupAll().reduceCount().value();
console.log(dma_grp);
Crossfilter isn't meant to be used in a way where you are building new dimensions and groups for each user interaction. It's meant to build dimensions and groups before interactions take place and then update them quickly when filtering based on user interactions.
It's not really clear from this question what your data looks like or what you are trying to do, but you probably want to create dimensions and group for your dma property and then build your map based on that:
var voter_data = crossfilter(my_data);
var dmaDim = voter_data.dimension(function(d) { return d.dma; });
var dmaGroup = dmaDim.group();
At this point dmaGroup.all() will be an array of objects that looks like { key: 'dmaKey', value: 10 } where 10 is the count of all records where d.dma === 'dmaKey'. There are lots of ways you can aggregate differently with Crossfilter, but that may get you started.
I've been searching for similar solutions out there but am coming up short so far. Here is what I want to accomplish:
I need to come up with a basic solution to sync inventory quantities at the end of each day. We take physical counts of inventory sold throughout the day but need something to log these changes and share between users. I would like to utilize two buttons (click one to subtract amount of items sold at the end of the day and click one button to add newly received inventory).
This is how my sheet is set up:
Col A: Product Tag
Col B: Product sku
Col C: Amount Sold Today
Col D: Total Inventory Quantity
Col E: Add New Inventory
Column D will be pre-populated with initial inventory counts. At the end of each day, I would like to go down my product list and fill in the amount of each item sold that day in Column C. Once Column C is fully populated, I would like to click the "subtract" button and have Column C subtracted from Column D.
On the other side, once we receive new stock of an item I would like to enter these counts into Column E. Once this column is fully populated, I would like to click the "Add" button and have Column E added to Column D. Ideally once the add or subtract function has been completed, columns C or E will be cleared and ready for the next days entry.
I already have designed my buttons, I just need help coming up with the scripts to accomplish this.
You can use Google Apps Script for this.
If you are unfamiliar, in your particular spreadsheet, go to Tools → Script Editor and then select the Blank Project option.
Then you can write functions like this to achieve what you want!
function subtractSold() {
var sheet = SpreadsheetApp.getActiveSheet();
var c1 = sheet.getRange("C2");
var c2 = sheet.getRange("D2");
while (!c1.isBlank() && !c2.isBlank()){
c2.setValue(c2.getValue() - c1.getValue());
c1.clear();
c1 = c1.offset(1, 0);
c2 = c2.offset(1, 0);
}
}
Basically what the function does is:
Get a reference to the active spreadsheet
Get references to the cells C2 and D2, for the first row of data.
Use a while loop to repeated go through the rows. Terminate when either cell is empty.
In the loop, we get the appropriate values, subtract and set the value back into the cell. Then we clear the cell in column C. We then move both cell references down by one row (the offset method returns a reference to the original cell, but offset by row, column).
Then assign the script to the button image by entering the name of the function (subtractSold in this case) in the "Assign script" option for the button.
I have made an example sheet here (go to File → Make a Copy to try the scripts and see the code): https://docs.google.com/spreadsheets/d/1qIJdTvG0d7ttWAUEov23HY5aLhq5wgv9Tdzk531yhfU/edit?usp=sharing
A bit faster
If you try the sheet above you can see it processes one row at a time, which might get pretty slow when you have a lot of rows. It is probably faster to process the entire column in bulk, but it may be a bit more complicated to understand:
function subtractSoldBulk() {
var sheet = SpreadsheetApp.getActiveSheet();
var maxRows = sheet.getMaxRows();
var soldRange = sheet.getRange(2, 3, maxRows); // row, column, number of rows
var totalRange = sheet.getRange(2, 4, maxRows);
var soldValues = soldRange.getValues();
var totalValues = totalRange.getValues();
for (var row in soldValues) {
var soldCellData = soldValues[row][0];
var totalCellData = totalValues[row][0];
if (soldCellData != "" && totalCellData != "") {
totalValues[row][0] = totalCellData - soldCellData;
soldValues[row][0] = "";
}
}
soldRange.setValues(soldValues);
totalRange.setValues(totalValues);
}
The difference here is that instead of getting one cell, we get one range of cells. The getValues() method then gives us a 2D array of the data in that range. We do the calculations on the two arrays, update the data in the arrays, and then set the values of the ranges based on the array data.
You can find documentation for the methods used above from Google's documentation: https://developers.google.com/apps-script/reference/spreadsheet/sheet
I am using Linq to entityframework to query some infomration. I am trying to use entityfunction.truncatetime and it doesnt seem to work as expected. here is my sample query
From d In Request
Where d.Requestor= "XXXX" And d.ProcessedFlag = "N"
Select d.RequestID, RequestReason = d.RequestReason.ItemValue, RequestType = d.RequestType.ItemValue, RequestedDate = EntityFunctions.TruncateTime(d.RequestedMoveDate)
The requesteddate doesnt seem to truncate the time part and I am still getting the both Date and time.
Am I missing something here?
In .NET, the DateTime class actually represents both a date and a time. Internally, this is stored as a numeric value represented by the number of 100-nanosecond "ticks" since Midnight, January 1, 1001 AD. This number gets "converted" when it's displayed (either in output or in a debugger). This conversion is done via a format string.
Even if you truncate a DateTime's time portion, it still has a time... it's just 00:00:00, and if you don't want to see that time, you need to adjust your format string to not convert that.
Thus, if you do something like this: DateTime.Now.Date it will display `10/15/2012 00:00:00" if you use the default date conversion string (or whatever is the default format for your culture).
If you want to only display the Date portion, then you must do something like myDate.ToShortDateString() or myDate.ToString("d").
EntityFunctions is a set of tools designed to be used in Linq to Entities queries, because doing DateTime formatting is not normally allowed in a query.
For example, this code does not work:
var q = from x in dc where x.BirthDate == DateTime.Now.AddYears(-15).Date select x;
You have to do it like this:
var q = from x in dc
where x.Birthdate == EntityFunctions.TruncateTime(DateTime.Now.AddYears(-15))
select x;
This will then generate the correct SQL to do date comparisons in SQL code. This is what the EntityFunctions are designed for, not truncating dates in the select portion (although it does work). But, even though the date is truncated, it will still have a Time component, it will just be 00:00:00, and you must use a date format string to present it to your users in the manner you intend.
cant you use ToShortDateString() like below?
List<DateTime> time = new List<DateTime>();
time.Add(DateTime.Now);
var WhatDate = from date in time
select new { Date = date.ToShortDateString() };
In your case try this
From d In Request
Where d.Requestor= "XXXX" And d.ProcessedFlag = "N"
Select new{ RequestID = d.RequestID, RequestReason = d.RequestReason.ItemValue, RequestType = d.RequestType.ItemValue, RequestedDate = d.RequestedMoveDate.ToShortDateString()};
Personally, I know just enough Linq to be dangerous.
The task at hand is; I need to query the DAL and return a list of objects based on a date range. Sounds simple enough, however the date is a string, and for some reason it needs to stay a string.
I spent some time with this a while ago and got a solution working but I am iterating through a list of objects and selecting individual records by date one at a time, this is badddd! If the date range spans more than a few days its slow and I don't like it, and I've even busted a few of the Sr devs around here for doing iterative queries, so I definitely don't want to be a hypocrite.
Here is the crappy iteration way... each date pegs the database, which I hate doing.
- This works
DateTime start = Convert.ToDateTime(RecipientSearch.TransplantSearchStartDate);
DateTime end = Convert.ToDateTime(RecipientSearch.TransplantSearchEndDate);
var tempselectQuery = selectQuery;
while (start <= end)
{
tempselectQuery = selectQuery;
string sStart = Convert.ToDateTime(start).ToString(ResourceFormatting.DateOnly);
tempselectQuery = (ObjectQuery<DAL.Recipients>)tempselectQuery.Where(item => item.TransplantDate == sStart);
if (tempselectQuery.Count() != 0) TXPlistQueryDAL.AddRange(tempselectQuery.ToList());
start = start.AddDays(1);
}
Here is my attempt at trying to get my query to work in one db call
- This does not work... yet
DateTime start = Convert.ToDateTime(RecipientSearch.TransplantSearchStartDate);
DateTime end = Convert.ToDateTime(RecipientSearch.TransplantSearchEndDate);
List<string> sdates = new List<string>();
// Put my date strings in a list so I can then do a contains in my LINQ statement
// Date format is "11/29/2011"
while (start <= end)
{
string sStart = Convert.ToDateTime(start).ToString(ResourceFormatting.DateOnly);
sdates.Add(sStart);
start = start.AddDays(1);
}
// Below is where I get hung up, to do a .contains i need to pass in string, however x.TransplantDate
// includes time, so i am converting the string to a date, then using the EntityFunction to Truncate
// the time off, then i'd like to end up with a string, hence the .ToString, but, linq to entities
// thinks this is part of the sql query and bombs out... This is where I'm stumped on what to do next.
selectQuery =
(ObjectQuery<DAL.Recipients>)
from x in entities.Recipients
where sdates.Contains(EntityFunctions.TruncateTime(Convert.ToDateTime(x.TransplantDate)).ToString())
select x;
The error i get as follows:
I understand why I get the error, but I don't know the proper LINQ code to be able to acheive what I am trying to do. Any help will be greatly appreciated.
Ughh I feel dumb. I tried a bunch of tricky little things to get x.TransplantDate to just a date only string within my Linq query, E.G. 10/15/2011
where sdates.Contains(EntityFunctions.TruncateTime(Convert.ToDateTime(x.TransplantDate)).ToString())
Turns out it already is in the correct format in the database, and if i simplify it down to just
where sdates.Contains(x.TransplantDate) It works. The reason I wasnt getting any records returned was because I was testing date ranges that didnt have any data for those specific dates... UGHH.
So in conclusion this ended up working fine. And if anyone is doing something similar maybe you can learn from this example.
DateTime start = Convert.ToDateTime(RecipientSearch.TransplantSearchStartDate);
DateTime end = Convert.ToDateTime(RecipientSearch.TransplantSearchEndDate);
List<string> sdates = new List<string>();
while (start <= end)
{
string sStart = Convert.ToDateTime(start).ToString(ResourceFormatting.DateOnly);
sdates.Add(sStart);
start = start.AddDays(1);
}
selectQuery =
(ObjectQuery<DAL.Recipients>)
from x in entities.Recipients
where sdates.Contains(x.TransplantDate)
select x;
