SQL help

I just started learning SQL. I downloaded mySQL and I know some basic stuff like making tables, getting info from them and inserting info. I don’t know where to go from here. I want to have my database online so on my website people will fill out forms and the info will get stored in the database. I want this so I can have a game and all the stats would be stored in the database. I just don’t know what to do though. I don’t know how to get it online or any of that stuff. Please someone tell me what to do. Thanks.
