About the class

This class After learning mainly about the most basic essential grammar of SQL (SELECT, WHERE, ORDER BY, GROUP BY, etc.), I became familiar with the grammar by solving examples that can actually be used based on thisI want to cancel it. The course covers everything from basic things you need to understand before learning SQL to using SQL that can be used directly for work at a beginner level.

I recommend it to those who are new to SQL, those who want to find out what SQL is in a short period of time, those who are worried about how to create an environment where they can study SQL, and those who have learned SQL but are still unable to use it for work because they don't understand it well.

For those who haven't started SQL yet because they don't have time, no one to ask, and the existing courses are too difficult, I've prepared only the essential content in an easy and concise manner. For those who want to see more examples Hackerrank's SQL EASY problemsI recommend that you try using the SQL you learned while solving.

What makes this class special

An incumbent developer tells you

Practice-oriented SQL grammar for beginners

It's clearly explained so that even those new to SQL can understand and apply it. Since you learn from practical developers who use SQL in business, you can select and learn only the key points, focusing on the grammar used in practice.

I've tried to explain the concepts and terms that many beginners find difficult to use in terms that touch as much as possible. To prevent understanding of data from getting in the way of studying SQL, we have prepared a cafe menu that you can easily access in real life, so feel free to take the course!
