dloser, just according to the raiting of most demanded languages, it seems to be pretty nice thing to learn. But i don’t even know what this language is about and what is capable of :( .
“Pretty nice” apparently means something different to you than it does to me. I’m also not saying “don’t learn it”, just that it is an odd thing to pick it as your first language. But perhaps first figure out what SQL actually is…
SQL is a language to communicate from a server to a database, it’s not a programming language such as the others programming languages of your picture.
It depends on what you want to be? If you want to be a DBA, you just need knowledge of SQL, but if you opt for programmer then you have to learn at least one programming knowledge.
In case you opt for hacker, you will have to learn many!
