SQL database integration?

I want to have a way to access an sql server from Roblox. I don’t really understand http requests or even how to access it outside of Roblox. Any help is appreciated.

Check out the functions available. There is more info and code samples available if you click on them. Http service functions similar to remote functions. You send a request and get a response.
You will have to program on both sides for this to work or use API if you are not the host of what you are trying to access.
