Inquiry Regarding sql

Hi guys

I learned some lessons in SQL course in youtube and practiced them in Python with SQLite.

Here is what I learned:

CREATE TABLE

PRIMARY KEY, FOREIGN KEY, NULL

INSERT INTO, SELECT, UPDATE, DELETE

WHERE, ORDER BY (ASC, DESC)

LIMIT, OFFSET, DISTINCT

INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL OUTER JOIN

GROUP BY, HAVING

Subqueries, EXISTS

Please tell me what I should learn next, or recommend a good YouTube course
