In this advanced SQL course, you’ll learn how to add If-Else logic to queries using CASE statements, and how to use string functions to get just the part of text you need. Subqueries enable you to dynamically grab data from anywhere in a database and use that result in another query.
You (or someone else) may not have the database permissions to query tables directly, so learn how to query using Views instead of tables. Finally, you’ll learn the how variables, functions, and stored procedures can be used to make SQL code more reusable, flexible, and repeatable.
By the end of this advanced hands-on course, you’ll know more in-depth SQL techniques that better prepare you for a job in data analysis, data science, or any role requiring you to use SQL to work with data in databases.
SQL proficiency equivalent to our SQL Level 2 course is required, including JOINs, aggregate functions, GROUP BY and HAVING, as well as working with CAST and date/time.
From our hands-on training style to world-class instructors and custom-crafted curriculum, we deliver results our alumni are proud of.

The Career Centers instructors are highly skilled communicators who really know their craft. They are wonderful about explaining and re-explaining when necessary and I never felt rushed or foolish for asking a question.
