SQL Intermediate Course
Take your SQL skills up a level
Our Intermediate SQL course builds upon the skills learnt in our SQL Beginner course.
In this SQL course, you will move beyond using basic SELECT clauses for retrieving data. Learn to work with many different types of functions and expressions that modify the way data is returned in the result set. Students will use built-in T-SQL functions for working with string, date and numeric data types and will calculate moving averages, running totals and percentages using window functions.
Learn to use subqueries to perform more complex querying and to use views to to simplify querying. Students will also create their own user-defined functions to encapsulate business logic and improve efficiency. Read our course outline below.
