The best method I have is, enable the read/write connection within access and then create a DSN file in notepad using the following text:
DRIVER=SQL Server Native Client 11.0
Save the file with the extension .dsn
You can then load this as a file data source in access or wherever to create a linked table.
As with any linked table you will not be able to edit the table design.
At present, PowerApps is unable to connect to Access. I suggest you export Access data to excel or store data in Azure database.
What issues did you meet? Could you provide error message or screenshot about the issue?
More information about Azure SQL Database for your reference:
Yes, it is possible to connect to an Access Web App. I assume that you know how to get the server, database, username and password information from Access, but if not here is how.
Enable Connections for your Access Web App
Then in PowerApps the source type to use is SQL Azure, and you will be asked for a connection string. Use the following
Server=tcp:MYSERVER.database.windows....,1433;Database=MYDATABASE;User ID=MYUSER;Password=MYPASSWORD;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;
This worked very well for me. Please let me know if anything is not clear.
Hello DeanWang, an Access Web App is actually an Azure SQL database back end generated in SharePoint where the web front end is edited in Access desktop. I love it for simple rapid application development but unfortunately it seems Microsoft is not putting any effort in further developing it.
Whenever I have tried to connect to the back end in other instances, it comes up with asking to configure the IP firewall, which you cant do with the Web app's azure DB
I can confirm success in writing to the back end of the Access Web App. In Access I left the option of "From Any Location" selected, I am not sure if that is your issue. Also, to be clear I am using SharePoint online (as part of an Office365 subscription) and not on premise.
When you say "it comes up with asking", what is "it"?
I create Access Web Apps and sell them on the App Store and having been looking at Power Apps for a while. It's certainly possible to create read/write connections to AWA databases (as long as they aren't deployed 'locked' which mine are) - this looks like a very promissing way to build a hybrid mobile / web application (which is, after all, what most apps end up being). At the moment, there are limitations on the controls you can bind to the data etc - but I'm sure that will change soon.
I have also tested connecting a Flow to an AWA database and running a Data Macro from the AWA back end (which is basically a stored procedure) within the flow. You can't trigger a flow based on a new record in SQL yet - but it still opens up some possibilities.
