I need help !!

I`m new in "SQL" I saw some tutorial on YT but it`s not very helpful ... I install MySQL server on my PC and now I want to start with SQL ( creating table... ) but I don`t know how to make that on HeidiSQL so is there anyone who can help me ... I saw video but it`s on BD and I don`t understand it... So English will be "the best" ... Video or text tutorial "D

Take a look at the w3schools SQL tutorials, probably a decent start.

Best advice I can give you is work with the actual SQL language as much as possible, avoid the tools/wizards that create queries, tables and databases for you or you'll never learn!
