Stuck on simple table query, nothing show, desperate

Grafana
1

I want to understand how to create simple tables and dashboard with grafana connected to mysql.

I followed an example, as in the screenshots.

I’ve created a db for the example, the query is working in mysql, I inserted the query in the table sql editor, but nothing is showing.

The datasource was saved correctly, I don’t see any error

It should be something really stupid but I’m stuck.

well, the “view” buttons on the right show the result, but it takes some time (docker connected to local mysql), so I was clicking on and off and I didnt understand the meaning.
Finally I noticed a little pinwheel on the left, trying to calculate the result.
It was enough to wait a little bit…
