Download Image from SQL Server

We have an app that uploads images to a SQL server and displays them within the app. 

 

The user needs to be able to download the selected image in a gallery to their local device. 

 

Is this possible to do from the app or flow?

In Flow you can use the OneDrive connector to save images to your OneDrive. See below

The tricky part is the File Content. How are you storing the image in SQL?

I believe it is of binary type. @EricLott

That's good. That's what Flow expects.

@EricLott This hexadecimal value that @nvrhughes showed is how the image is stored in SQL Server, but when accessing it on PowerApps it turns into a value like this
"appres://datasources/'Your DataSourceName'/table/'Your Table Name'/rows/'Row Number'/inline/'Your Image Column Name'".
So when using the method you showed saves a text like this on a file.
I'm trying to find workarounds but without success... Any other ideas?

Hi

I encountered the same issue and got your results.

So I tried to retrieve the Image File stored in SQL directly from SQL and not from Powerapps. It works like a charm

 

first "get the row (V2)" via ID from SQL, then "create file" in OneDrive using the column from SQL.
works for me
