Error connectin to mysql through gateway if table contains guids

Hi,

 

I'm testing powerApps for my organization.

I was able to create a local gateway, a mysql connection and a test app using database structure.

If I use a straight table with only one integer field and a text field, I'm also able to show records inside the app.

 

The matter is that all of my tables use Guids and if I try to connect to any of them I receive an error asking to change the OldGuids parameter to True. 

Where should I set this parameter? I can't find any possibility in Mysql connection setup and in Gateway setup.

Can you help me with this issue?

Thanks in advance.

Luca

Hi @lrealdon,

 

Could you please share a bit more the error message within your app?

 

Currently, I could not reproduce your issue on my side. Please check and see if the following blog would help in your scenario:

https://paultebraak.wordpress.com/2015/12/08/mysql-import-issues-with-power-bi-and-oldguids/

 

Based on the above blog, it seems to tell that the data format error would show up if you use GUIDs within your mysql table.

 

If you want to change the OldGuids parameter to True within PowerApps. I afraid that there is no way to achieve our needs in PowerApps currently.

 

If you would like this feature to be added in PowerApps, please submit an idea to PowerApps Ideas Forum:

Best regards,

You're right. That's exactly the error I found.

 

Can you please tell me which version ap mysql are you using which does not create the issue?

In my case I found innoDB 5.5.35.

 

The field causing the issue is an autogenerated 36digits long CHAR, defined as Primary Key. (ex. 103645c5-0ad5-5f29-c6af-571cd336b10e).

 

Can you please confirm you tested the same environment?

Thanks.
