The only coursework you require to learn learn the foundations of SQL!
Are you new to SQL, or looking to relearn the basics?
HANDS-ON SQL For Beginners is the coursework to get you started! This coursework teaches you SQL through short instruction with accompanying SQL practice issues.
So there's plenty of beginner SQL courses on the net. What makes this different?
The thing is, most courses teach the material, & at best, show you a few examples. Even in the event that they ask you to solve an issue, there is not anywhere for you to actually enter your answer, so most people finish up skimming past that section without actually applying themselves.
