Advanced SQL Training NYC - Learn Database Management with SQL

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.

This course has a prerequisite

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.

Belinda Brewster-Clemence

Great class, learned a lot about SQL via the bootcamp.

Adam Harari

Peter was very thorough and knowledgeable. He really took his time to review the concepts and answer questions. Great overview of SQL content. I already had a basic understanding of SQL, but learned new information right from the first lesson. By the third lesson, it provided a great deeper dive into the database and table structures.
