Hi All,

Nice to connect with people in this forum.  
I would like to make data logger with flow below,  
PLC (Data source) -\> Node-Red -\> MySql database.

I have store value to database with function below :  
msg.topic = "INSERT INTO inject\_testing (HOD\_Ozone) VALUES (" + msg.payload.HOD\_Ozone + ");";  
return msg;

The next purpose is to get variable name as value and store it in database, for example the variable name is "HOD\_Ozone" then I need to get "HOD\_Ozone" store it in other variable to be able store in db.
