I've created a SQL practice environment!
Hello, this is Ttatji.
It must have been quite difficult setting up the practice environment, right? Installing Oracle, creating tables, inserting data...
No matter how much I tried to simplify it, many people still struggled.
So, I created a practice lab where you can execute queries directly on the web.
No installation required! Just come in and start typing your queries.
Example queries provided for each lecture chapter
Check ERD Schema
Now you can practice comfortably while listening to the lectures.
