Select top n from Azure SQL Databasee

I have an app which works with an Azure SQL Database.

 

We have a history screen which is intended to list the most recent incidents recorded in the database.

 

I have an expression which sorts the results, latest at top (i.e. descending).

 

I do not know how to limit the number of database records returned, which will certainly be to much for a non-delagable query.

 

I can create a SQL View, but I'd prefer to keep it clean within PowerApps.

 

In other development tools, I'd use a pass-through query.

 

Or I'd use a paged control and let the results be sent in chunks, with most users only needing the first n results.

 

Looking for suggestions on how to approach a solution.

Re: Select top n from Azure SQL Databasee

Hi @tom_garvin,

 

Please try to use FirstN function to return the last set of records of a table.

 

For your scenario, you could take the following function for a reference:

FirstN(SortByColumns(Filter(Testing2,StartsWith(Title,TextInput1.Text)),"Created",if(SortDescending1,Ascending, Descending)),10)

 

Please have a try with it and feel free reply if you need more help.

 

Besides, please post PowerApps related issues on PowerApps forum so that you could get the most qualified answers.
