Distinct Limited to 500 records?

(0) ShareShare
ReportReport
Posted on by Dandev 7

HI, I am building an app which books patient notes in - i am getting location and user information from an SQL DB and i have a lot of locations and a lot of users respectively, the issue is that i am using a combo box to call the users/locations dependant on where the user would like to book the patient notes to. my issue is that its only fetching me 500 records back when using distinct. here is my code...

 

If(Dropdown2_2.Selected.Value = "User",Distinct('[dbo].[View1]',Name),Distinct('[dbo].[View2]',Name))

 

any ideas on how to bypass this 500 record limit?

    Option 1 is to modify the filter to further narrow down the number of items being returned. Option 2 is to go to app settings --> advanced, and change the data row limit for non-delegable queries, and increase it from the default of 500. You may want to first read the announcement of this feature here, which also provides guidance. Option 3 is to reconfigure the database so that the distinct list is available via a separate table or a view. (this wouldn't get past the 500 limit, but it would ensure that the distinct list is generated from the server, so PowerApps wouldn't have to call the distinct()).

    Hi @Dandev ,

     

    This is because that  Distinct using Azure SQL doesn't support delegation. You can change the limitation number from 500 to 2000 under File tab, select App settings. Under Experimental features, change the Data row limit for non-delegable queries setting to 2000.

     

    If you need this feature, you could vote on below idea which status is under review:

    Please Extend delegation to Distinct
