No, where it says *** Property, change it from msg.payload to msg.topic
No. Change the Property field at the top to say topic rather than payload, and leave the Template as you had it before:
SELECT rfidno FROM rfid1
WHERE rfidno='{{payload}}';
ok Done ,Now Tell
Great, so now run your flow with a good RFID and a bad RFID and show the results.
What to write in switch node and change node
You may have missed where I suggested:
I then recommend you add a
Debugnode after the mysql node so you can see exactly what it is returning. That will help you/us identify how to configure the Switch node to test if the query found a match or not.
Until we can see what the mysql node is returning for both a 'good' result and a 'bad' result, we can't tell you how to configure the Switch node.
sure check this ones
Now run with a bad RFID and show the results
Now add this change node after the mysql node and it will output one side of the output for a good RFID and the other for a bad RFID.

No. He gave you a piece of JSON in his last reply. Copy that JSON, then import it into the editor. That will give you a switch node that is configured to separate out the good and bad messages.
Did you import the change node I provided in my last post? If not, please import it and remove the change node you created.
ya i have done it shows a switch node poped up
i changed the "switch" to "change" in json object
