Top Five Things to Know in Advanced SQL

This is the repository for the LinkedIn Learning course Top Five Things to Know in Advanced SQL. The full course is available from LinkedIn Learning.

In this course, Kendall Ruber shows you how to build on your existing knowledge of basic SQL commands by introducing advanced SQL concepts and providing hands-on exercises for you to apply these skills to common business problems. By the end of this course, students should understand the different use cases and limitations for various advanced functions in SQL, as well as be able to appropriately apply these functions to solve business problems. Learn and practice how to construct subqueries, CTEs (Common Table Expressions), and windows functions.

Instructions

This repository has branches for each of the videos in the course. You can use the branch pop up menu in github to switch to a specific branch and take a look at the course at that stage, or you can add /tree/BRANCH_NAME to the URL to go to the branch you want to access.

Branches

The branches are structured to correspond to the videos in the course. The naming convention is CHAPTER#_MOVIE#. As an example, the branch named 02_03 corresponds to the second chapter and the third video in that chapter. Some branches will have a beginning and an end state. These are marked with the letters b for "beginning" and e for "end". The b branch contains the code as it is at the beginning of the movie. The e branch contains the code as it is at the end of the movie. The main branch holds the final state of the code when in the course.

When switching from one exercise files branch to the next after making changes to the files, you may get a message like this:

Please commit your changes or stash them before you switch branches.
Aborting
