Creating records from a Date Range

Posted on by bscramling

I am trying to create records in a datasource (SQL Server) based on a user inputted date range. (The user supplies the first date (StartDate) and the last date (EndDate).

Utilizing the following code...

Set(TotalDays,RoundDown(DateDiff(StartDate.SelectedDate, EndDate.SelectedDate, Days) / 7, 0) * 5 +
Mod(5 + Weekday(EndDate.SelectedDate) - Weekday(StartDate.SelectedDate), 5) -
CountIf(PTDHolidays, Date >= StartDate.SelectedDate, Date <= EndDate.SelectedDate) + 1)

//Code supplied by Anh-Thu Chang, PowerApps Community Manager

...I am able to set a variable to the correct amount of dates (excluding weekends and our company holidays). So at this point I now know the first date, the last date and the amount of valid dates between them. From this I want to create a record in my datasource for each date. The records will be identical except for the date.

I've checked out all the posts about ForAll and Collections, as well as Lookup, Filter and Patch. What I can't figure out is how to iterate through this range, so I can record their individual values, say, in a Collection. Once I have them in a Collection then I can use ForAll and Patch to update my SQL datasource.

I hope I explained this clearly and somebody can steer me in the right direction. Any input will be appreciated.

You can use an expression like this one to store all the days that you need to insert into a new collection. The idea is to create all possible days between the start and end dates (and for now you need to specify all the numbers from 0 to the maximum number of days yourself - the example below works for up to 50 days), then filter all of those that are either on a weekend or on a holiday.

ClearCollect( DaysToStore, Filter( AddColumns( [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49], "Day", DateAdd(StartDate.SelectedDate, Value, Days)), Day <= EndDate.SelectedDate, Weekday(Day, StartOfWeek.Saturday) > 2, IsBlank(LookUp(PTDHolidays, Date = Day))))

Hope this helps!

Thanks Carlos your code works perfectly. For my use case no filter for holidays/weekend was required so I adjusted your code like the following:

ClearCollect( DaysToStore, Filter( AddColumns( [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49 ], "Day", DateAdd( StartDate.SelectedDate, Value, Days ) ), Day <= EndDate.SelectedDate ) )
