입문
SQL, MySQL
Datalian's SQL intermediate problem-solving lecture with over 10,000 cumulative students and rich online/offline lecture experience. We will solve several problems together to practice the SQL intermediate theory.
Importing data with SQL
Develop your query writing skills by solving various problems!
Seeing is believing! Take your SQL learning to the next level.
Solve the problem yourself with Datalian.
There are many SQL theory lectures,
Why aren't there any courses where you can really develop your skills by solving a lot of problems ?
Just as no matter how much you study English grammar, your English conversation skills will not improve if you don't actually have conversations,
You can't use SQL properly just by studying the grammar.
So I'm back with another lecture that's all about problem solving !
In this lecture, we will learn about GROUP BY, CASE, JOIN, etc. covered in the intermediate class.
We'll be leveraging a few new functions at a similar level:
Solve problems of varying difficulty.
(Problems covered in the advanced class , such as subqueries, can be found in the advanced problem-solving class scheduled to open soon.)
I recommend this course to anyone who wants to practice writing queries for work or SQL coding tests !
This lecture will combine HackerRank ( hackerrank.com ) and LeetCode ( leetcode.com ) problems. Before attending the lecture, we recommend registering for both sites and browsing through them first.
Who is this course right for?
People who have learned SQL theory but feel they lack practical experience
People preparing for SQL coding tests
People who need a problem-solving-focused SQL lecture
People who want to become data analysts
People who want to learn SQL for work
