I am new to ESP8266 programming.
Coming to the post,

am having the following components:
Arduino UNO,
ESP8266(wifi module),
RFID Reader and some RFID cards.


Following are working:
1.) I can able to connect ESP8266 wifi module to my wifi network using Arduino UNO ,
through AT+CIFSR I got the IP of module, I tried to ping its working fine.

2.) RFID reader connected with Arduino UNO , If I swipe my RFID cards on reader , I am able to display RFID ID numbers in serial monitor
Note : Its working when connected USB [PC to Arduino uno]


What am looking for ?

Using ESP8266 and Arduino UNO only ,
1.) can we post data to any database? without connected to serial port [i.e] by supplying external power supply . If so where to see the output ?

2.) I need to read the RFID through Arduino UNO , and post the data to cloud/any data base dynamically at each card swipe , through esp8266 .

RFID -- > Arduino uno [reading data ] ---> ESP8266 [access data from Arduino] --> Post to database

can anyone help with this.

Considering you are controlling the ESP using AT-commands (have you thought on loading the sketch directly to the ESP and ditching the Arduino, by the way?), I guess your best option is a web server. I would set up a MariaDB plus a PHP script, so you can send the information from the RFID card just by visiting a URL from the ESP (you can do that using AT commands).

Thanks for reply. In my case I am able to read rfid data and print on local webserver created using AT command . My requirement is to store the data in SAP HANA cloud by realtime whenever the data is read by RFID reader .

i.e to the particular table i created in the HANA Cloud. I need the coding for POST data from arduino to a URL.
