No handwaving. Exactly what does this mean?

Do you have an Ethernet shield? A WiFi shield?

yes i have. but i dont know how to sent data from arduino to database server. is it anycode for the sketch program? thanks before. sorry for my bad english

but i dont know how to sent data from arduino to database server.

The Arduino as EthernetClient example illustrates that.

Sending data to a server involves making a GET request (or a POST request, but the GET is conceptually easier).

After the name of the script to execute on the server, put a ? followed by name=value, where name is a name that the script expects, and value is the value you want to send. It you want to send multiple values, use & and name=value for the second and subsequent data.

Some examples:
GET /someScript…php HTTP/1.1 <— Get some web page from the server
GET /someScript.php?temp=37 HTTP/1.1 <— Have it store the temperature
GET /someScript.php?temp=37&humid=98 HTTP/1.1 <— Damn, it’s hot and muggy
