Hello. The grafana is used to view the data stored in the database.
However, I want to insert or update data using, for instance, a button and a label.
Is possible to do it in grafana? If not, is there another similar web program??
Best regards,
Hello 
and welcome to the forum, @josemspedro
short answer is no, no button to perform CRUD type operations from Grafana back into a DB (as far as I know). My understanding is that Grafana is a visualization platform and generally queries data sources in a read-only kind of way
what data source are you using?
Helllo @mattabrams and thank your for your reply.
I am using MySQL as data source.
Do you know some program that I could write and read in the data source??
Node-RED integrates very nicely with MySQL. You can also set up a Node-RED dashboard with buttons, etc. to update your database.
