What are the requirements for learning SQL??

Question

what is the scope of SQL?

Answer 1

The requirements for learning SQL here in Sololearn are none (maybe knowledge of some concepts of IT), so you can learn it as the beginner.
But the next question is what after this course. Because in this course it is leaned only a handy simple output or input SQL.
But in real programming you have to call SQL commands from your programimg language and transfer values between database - SQL -your program - clients GUI (a desktop window or a web page] So you have to learn next some programming language - maybe some of them here.. But here is only a basic of this knowledge. You have to learn more of this language after., how to use SQL in it, how to create GUI , and so more..
