While I was going through your SQL video lecture, I saw a mistake in the sql query of stored procedures in the dropping procedures video lecture as mentioned below where I noticed a text of Correction : Lines 4 & 5 should be switched was showing instead of it should be Line 5 & 6.
I hope you should make corrections properly so that the enrolling student in your course might not get meshup with the wrong understanding of SQL code structure.
1 DROP PROCEDURES IF EXISTS get_clients;
3 DELIMITER $$
4 CREATE PROCEDURE get_clients()
5 SELECT * FROM clients;
9 DELIMITER ;
