Auto Incrementing function

Posted on by deepaks1

Dear Experts

I'm seeing an issue in generating auto increment numbers in my ID column. I'm using below formula to generate auto numbers (

(ThisItem.id) &
First(Sort('Data base name',id,SortOrder.Descending)).id+1)
 
I've Edit form and gallery connected to each other and sql as data source.
 
For the new record auto number generation is working fine, but when I try to update existing record by clicking the gallery, the id column is not behaving as expected. In the below example if you look at the id column in edit form as "1928" (1 is the existing id record and 928 is the next auto increment number), when I click Item ID 1 to edit, next auto increment number (928) is not disappearing instead it adds to existing id number. See below screen shot. Anyone can give me a solution, please.

Hi deepaks1
Is your Id column numeric or text. If a number,
1000 + First( Sort( 'Data base name', id, SortOrder.Descending ) ).id + 1

If text
ThisItem.id & Value( First( Sort( 'Data base name', id, SortOrder.Descending ) ).id ) + 1

Hi @WarrenBelz

Thanks for your reply.

My id column is a numeric column, as you suggested I used:

1000 + First( Sort( 'Data base name', id, SortOrder.Descending ) ).id + 1

the last item id in my source is: 466666, when I clicked "Add new record", id column should have populated 466667 instead it is populating: 467667

when I clicked an existing item : 917, all column values are populating correctly except id field, id column is not showing the selected value.

OK - I am now quite unclear - what exactly are you adding at the start (in your initial post) as it seems you simply need the bottom part of the formula

Ok, My id is a number field, I'm looking to auto increment next id number when "Add New record" button is clicked and when an existing record is clicked, id field should display the clicked id# in the edit form. I tried the formula you gave me and it is not displaying correct id# (existing record in gallery). Hope this makes it clear.

As I mentioned, you should just need
First( Sort( 'Data base name', id, SortOrder.Descending ) ).id + 1

Your initial post suggested you were adding something to the front, but this does not appear to be the case
