After studying at the academy for a while, I got a job in a data-related job, and I heard that there are many cases where I have to deal with SQL in the field! I only learned the very basics at the academy, and since I only used crud as a query in the project, I have never used joins, conditional statements, subqueries, window functions, etc. I wanted to do my part quickly without struggling in the field, so I took the Datalian intermediate class separately, and I am very satisfied. I plan to leave a review and continue listening to the intermediate class problem solving + advanced class lectures!
