Filtering/sorting rows in query editor gives an error

[KellyLen]

Hello,

I have problem. I can do anything else in my query in query editor but filtering rows. When I try to filter or sort column, then it gives an me an error:

Does anybody know, why this error comes only in sorting or filtering? How to solve it?

Best regards,

Kelly

I get this aswell from time to time.

Im pretty sure it has to do with your connection.
Where do you get your data from?
