How to add "No Configuration Found" message when no data returned from DB

Hi Minijohn,

Thanks for your reply. As I mentioned I am very new to this tool, I am not sure what do you mean by states.
I'll explain what I am trying to do.
I am using Query JSON with SQL and written query and binded to grid. Till this point it is working fine.
Now I want to display "No Configuration Found" message, if there is no records in DB, to achieve that i have enabled Transformer which is below my query.
Please find below screen shot for the same, so this you will get fair idea.

I am not sure where this went wrong, it is not working - please help me to achieve this.

Thanks,
Lalitha.C
