I want to implement a running distinct count with Amazon Quicksight. Here's an example of what that would look like:
Date
ID
Amount
Running Distinct Count
1/1/1900
a
1
1
1/2/1900
a
3
1
1/2/1900
b
6
2
1/4/1900
a
3
2
1/8/1900
c
9
3
1/22/1900
d
2
4
I've tried runningSum(distinct_count, [Date ASC]), but this returns a sum of the distinct counts for each aggregated date field.
Can this be implemented in QuickSight?
You can use this workaround to get the same functionality as runningDistinctCount() as follows:
runningSum(
distinct_count(
ifelse(
datetime=minOver({Date}, [{ID}], PRE_AGG),
{ID},
NULL
)),
[{Date} ASC],
[]
)
This would give you the runningDistinctCount of ID's over the Date field. It achieves it by considering just the first time the ID appears in the dataset, counting these and finally doing a runningSum on these counts.

In my game application I have a combats table:
id player_one_id player_two_id
---- --------------- ---------------
1 1 2
2 1 3
3 3 4
4 4 1
Now I need to know hoy many unique users played the game. How can I apply distinct, count on both columns player_one_id and player_two_id?
Many thanks.
By using union you can get unique distinct value.
$playerone = DB::table("combats")
->select("combats.player_one_id");
$playertwo = DB::table("combats")
->select("combats.player_two_id")
->union($playerone)
->count();
I want to calculate tasks per day(no of tasks/no of unique users) in my dashboard.
I used the distinct count to get the unique no of employees. When I put the measure in pivot, day wise calculation is okay but at the end in MTD it is not added the day wise unique no of emp.
Tasks per day:=divide(sum(fdata[resolved]),distinctcount(fdata[sap id]))
I expect the output like second table.
Model
Date ID Resolved
12-05-2019 a 1
12-05-2019 a 1
12-05-2019 b 1
13-05-2019 a 1
13-05-2019 b 1
13-05-2019 c 1
Expected Result
Date No of emp Resolved Task Per Day
12-05-2019 2 3 1.5
13-05-2019 3 3 1
Grand Total **5** 6 1.2
This will do the trick:
Tasks per day:=
IF(
ISFILTERED( fdata[date] )
, DISTINCTCOUNT( fdata[sap id] )
, COUNTROWS(
GROUPBY(
fdata
, fdata[date]
, fdata[sap id]
)
)
)
I have data as follows
EmployeeID Cycle Val Group
1 1 6 A
2 1 5 A
My desired result is as follows:
EmployeeID Cycle GroupVal
1 1 5.5
2 1 5.5
I have written 2 Measures as follows:
Emp_AVG: CALCULATE(AVERAGE(EmployeeFeedback, EmployeeFeedback[Val] > 0)
Group_AVG: CALCULATE(AVERAGEX(EmployeeFeedback[Emp_AVG],EmployeeFeedback[Emp_AVG] >0)
My thought process is that the Group_AVG is averaging the avg of all employees PER GROUP however since i need the results for a SPECIFIC employee, as soon as i introduce that column, it starts slicing by the Employee and the Group avg becomes inaccurate. I guess i need to generate Group Avgs before i do any employee filtering..how?
I am running a DAX query as follows:
EVALUATE SUMMARIZECOLUMNS(
EmployeeFeedback[EmployeeID],
EmployeeFeedback[Cycle],
"Group Val", [Group_AVG]
)
I need the EmployeeID to filter it down to an employee but because of EmployeeID, the Group AVG gets screwed. Without EmployeeID, Group AVG is correct but then there is no way to filter it for a specific Employee!
Thanks!
You could try to provide the ALLEXCEPT() argument to the CALCULATE function.
Btw, I believe there's an error in your Emp_AVG measure.
Try this:
Employee Average
Emp_AVG =
CALCULATE(
AVERAGE(EmployeeFeedback[Val]),
EmployeeFeedback[Val] > 0)
Group Average
Grp_Avg =
CALCULATE(EmployeeFeedback[Emp_AVG],
ALLEXCEPT(EmployeeFeedback,EmployeeFeedback[Group]))
Result:
I have one table scores where I have saving users scores. It's looks like this
table `scores`
id | points | user_id
1 5 1
2 2 1
3 4 1
4 1 3
5 10 2
I want to select each user, sum his points and show as a ranking. The result from above should be
user_id | points
1 11
2 10
3 1
The query with which I came up is
$sumPoints = Scores::select( \DB::raw("sum(points) as numberOfPoints"), \DB::raw("count(id) as numberId"))->groupBy("user_id")->first();
The problem is in ->first() because it's return only one result.. it is working as must. If I try to use ->get() instead I've got Undefined property error. How should I use this?
The query which is working in phpmyadmin
SELECT count(id) as numberId, sum(points) as numberOfPoints FROM `points` GROUP BY `user_id`
You can use something like this
$sumPoints = Scores::select( \DB::raw("sum(points) as numberOfPoints"), \DB::raw("count(id) as numberId"))->groupBy("user_id")->get();
foreach($sumPoints as $point){
dd($point); //OR dd($point->numberOfPoints)
}
I would like to try and sort this data by descending number of events and from latest date, grouped by ID
I have tried proc sql;
proc sql;
create table new as
select *
from old
group by ID
order by events desc, date desc;
quit;
The result I currently get is
ID Date Events
1 09/10/2015 3
1 27/06/2014 3
1 03/01/2014 3
2 09/11/2015 2
3 01/01/2015 2
2 16/10/2014 2
3 08/12/2013 2
4 08/10/2015 1
5 09/11/2014 1
6 02/02/2013 1
Although the dates and events are sorted descending. Those IDs with multiple events are no longer grouped.
Would it be possible to achieve the below in fewer steps?
ID Date Events
1 09/10/2015 3
1 27/06/2014 3
1 03/01/2014 3
3 01/01/2015 2
3 08/12/2013 2
2 09/11/2015 2
2 16/10/2014 2
4 08/10/2015 1
5 09/11/2014 1
6 02/02/2013 1
Thanks
It looks to me like you're trying to sort by descending event, then by either the earliest or latest date (I can't tell which one from your explanation), also descending, and then by id. In your proc sql query, you could try calculating the min or max of the Date variable, grouped by event and id, and then sort the result by descending event, the descending min/max of the date, and id.
