It's a good site to get a basis, though it won't teach you how to code entirely

This ^^

Without question, It's an excellent learning source but when I sifted through the SQL side of It, It's very basic that barely covers how to select, query and manipulate databases, tables and columns effectively. It's missing a lot of functions, clauses, operators and data types as well. Having said that, those starting SQL, will certainly find It of benefit. They can then further their knowledge via their own volition.
