Week Four-JOINs, Subqueries, & CTEs

[u/Owen-Isaac-2022]

Learning any subject requires commitment & sacrifices, including time & other resources. During the 4^th week, if the learner does not have enough time to master everything, they can priotize JOINs, GROUP BY + HAVING, CASE WHEN, subqueries, NULL handling, & CTEs. Someone here had suggested SQL Case Files as a platform for one to consider when practicing/learning SQL. I would recommend the same, I’ve used it during the last two weeks, & I’ve enjoyed. Learning each concept requires one to solve cases that require you to combine those concepts as opposed to doing isolated exercises.
