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 simplify querying. Students will also create their own user-defined functions to encapsulate business logic and improve efficiency.
By the end of this course, you will be able to:
- Work with an Azure SQL database and write queries using Transact-SQL (T-SQL)
- Use built-in T-SQL functions and create user-defined functions
- Write subqueries and create views to organise and manage data efficiently
Prerequisite:
This course builds on the knowledge gained and skills taught in our SQL Beginner course. Participants should be comfortable writing basic SQL queries.
