Quickly learn from basics to practical application.
There are many SQL theory lectures, but why aren't there any courses that can help you build real skills by combining them with problem-solving practice?
Just like studying English grammar alone won't improve your conversational English skills without actual practice,
SQL also cannot be used properly by only studying grammar.
The Basic SQL course aims to help you learn the syntax of the three most fundamental SQL functions (SELECT, WHERE, ORDER BY), and then become familiar with writing queries by solving problems so you can actually apply the SQL syntax you've understood conceptually.
For those who want to apply SQL directly to their work, for those preparing for SQL coding tests, this is a helpful course.
If you take both the SQL basics course and the upcoming SQL intermediate course, you'll be able to develop the skills to easily solve Programmers' SQL High Score Kit problems.
Who is this course right for?
People who want to become data analysts
People who want to start learning SQL without any preparation
People who have learned SQL theory but feel they lack practical experience
People who need a problem-solving-focused SQL lecture
People preparing for SQL coding tests
