Power Apps SEQUENCE Function

Power Apps SEQUENCE Function

Yesterday the SEQUENCE function was announced on Microsoft’s official Power Apps blog. I thought I’d provide some details on how to use SEQUENCE since the Power Apps documentation does not yet include a page for it.


Description

The SEQUENCE function creates a range of numbers as a single column table. This could be a continuous range like the numbers from 1-to-100 or non-continuous range such as [2, 4, 6, 8 10]. Ranges of dates and letters can be produced as well.


Syntax

Sequence(records, start, step)

  • records – Required. Quantity of numbers in the sequence.
  • start – Optional. Starting number of the sequence. Default is 1.
  • step – Optional. Incremental value. Default is 1


Examples


Numbers

A table with all numbers from 1-to-10

Sequence(10)
Output: [1,2,3,4,5,6,7,8,9,10]


A table with all multiples of 10 from 0-to-100

Sequence(10, 0, 10)
Output: [0,10,20,30,40,50,60,70,80,90,100]


A table with numbers from 10-to-1

Sequence(10, 10, -1)
Output: [10,9,8,7,6,5,4,3,2,1]



Letters

A table of all letters A-to-Z

ForAll(Sequence(26, 65, 1), Char(Value))
Output: [A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z]



Dates

A table of the next 7 days starting 2020-01-01

ForAll(Sequence(7), Date(2020, 1, Value))
Output: [1/1/2020, 1/2/2020, 1/3/2020, 1/4/2020, 1/5/2020, 1/6/2020, 1/7/2020]


A table of the next 5 Saturdays starts 2020-01-04

ForAll(Sequence(5, 4, 7), Date(2020, 1, Value))
Output: [1/4/2020, 1/11/2020, 1/18/2020, 1/25/2020, 2/1/2020]


A table of the first day of each month in the year 2020

ForAll(Sequence(12), Date(2020, Value, 1))
Output: [1/1/2020, 2/1/2020, 3/1/2020, 4/1/2020, 5/1/2020, 6/1/2020, 7/1/2020, 8/1/2020, 9/1/2020, 10/1/2020, 11/1/2020, 12/1/2020]


A table of the last day of each month in the year 2020

ForAll(Sequence(12), DateAdd(Date(2020, Value, 1), 1, Months) - 1)
Output: [1/31/2020, 2/29/2020, 3/31/2020, 4/30/2020, 5/31/2020, 6/30/2020, 7/30/2020, 8/31/2020, 9/30/2020, 10/31/2020, 11/30/2020, 12/31/2020]


A table of all of the days in the month of January for the year 2020

ForAll(Sequence(Day(DateAdd(Date(2020, 1, 1), 1, Months)-1), 1, 1), Date(2020, 1, Value))
Output: [1/1/2020, 1/2/2020, 1/3/2020, 1/4/2020, 1/5/2020, 1/6/2020, 1/7/2020, 1/8/2020, 1/9/2020, 1/10/2020, 1/11/2020, 1/12/2020, 1/13/2020, 1/14/2020, 1/15/2020, 1/16/2020, 1/17/2020, 1/18/2020, 1/19/2020, 1/20/2020, 1/21/2020, 1/22/2020, 1/23/2020, 1/24/2020, 1/25/2020, 1/26/2020, 1/27/2020, 1/28/2020, 1/29/2020, 1/30/2020, 1/31/2020]


Random

A random number between 1-and-100

First(Shuffle(Sequence(1, 100, 1))).Value
Output: 67 (changes to another random number each time)

Hi Matthew,

I got the validation for duplicate date range to work on the calendar app that I’m building. I tested the sequence function separately to create recurring meetings and it worked but when I combined it together, it does create recurring meeting but it stopped validating for conflict date range.
My SharePoint list has StartDateTime and EndDateTime column. I set the Start and End as below and from there set the conflict as varRecord and if it’s empty it should patch with the sequence function. If it’s not blank, then I should get notification error.

Set(Start, start.SelectedDate + stime.Selected.Value);
Set(End, end.SelectedDate + etime.Selected.Value);
Set(varRecord, LookUp(‘Anchorage Working Calendar’, StartDateTime <= Start && EndDateTime > Start || StartDateTime > Start && EndDateTime <= End || StartDateTime < Start && EndDateTime > End));

If(IsBlank(varRecord.ID),
ForAll(Sequence(Value(‘days/weeks’.Text)) As recurringmeetings,Patch(‘Anchorage Working Calendar’, {‘Client Name’: Client.Text, StartDateTime: start.SelectedDate+(recurringmeetings[@Value]*7)+stime.Selected.Value, EndDateTime:end.SelectedDate+(recurringmeetings[@Value]*7)+etime.Selected.Value})),

Notify(“Date Conflict, Booking already exist for selected date and time!”, NotificationType.Error));

Not sure what I’m doing wrong 🙁 Any advise please. Thanks!
