handshaking a SQL server with Javascript

Question

I want to try, as a learning excersise, get my javascript to chat to sql.

var ws = new WebSocket("ws://127.0.0.1:1433");

doesn't seem to be a blocked port, so it should in theory work.

I am looking for a breakdown of how to handshake with the sql server, and chat with it.

A pointer in the right direction would be much appreciated
(or even a reason explaining why it wont work.)

I want to try this on Microsoft SQL 2008 R2.

Answer 1

MS SQL doesn't have a text based protocol to allow you to interface with it through telnet. You can use a web socket to determine of the target server is listening on 1433, but you're best bet for completing the login sequence is to use a sql client api.
