SQL Datasource, column data is not showing when "Disable explicit column selection" is off

I have an issue with an existing app when "Disable explicit column selection" is off

I'm using a gallery that is based off a view in SQL.

And upon clicking a button in the gallery, it runs the function: ClearCollect(SelectedActionLog,ThisItem);

However, the collection have columns where data is empty when "Disable explicit column selection" is off.

I see that this ""Disable explicit column selection" setting is retired. What does this mean for my app? and what is the work around?

Hi

What permissions do they users have, as they go through the gateway?

You may need to run those queries as either a) each user has the proper permissions or b) as a service account, where the users STILL need a license, but that you can simply have a Service Account do the queries so you only need to give them the required privs, which they do not have since that is off.

That's what I would do

Explicit column selection is a performance feature .

With explicit column selection enabled, Power Apps will retrieve only the data that corresponds to columns that are actually shown in your gallery.

This is the reason why your call to ClearCollect, includes empty columns.

To resolve this, you can look up the record rather than reference ThisItem

ClearCollect(SelectedActionLog, LookUp(YourSQLView, PrimaryKeyCol=ThisItem.YourPrimaryKeyCol) );

Alternatively, you can modify the Items property of your gallery and replace the reference to your SQL view to with a call to ShowColumns that explicitly specifies the columns that you want to retrieve.

ShowColumns(YourSQLView, Column1, Column2, Column3, etc)
