Description
Learn how to write effective and accurate SQL with this course!
You will learn how to read and write complex SQL queries in a relational database (SQL Server). The skills you will learn are also largely applicable to any other major database system, such as MySQL, PostgreSQL, Oracle Database, and much more.
Knowing how to write SQL is one of the fastest ways to reach your career goals. This is because SQL is consistently the most in-demand skills in the tech sector.
SQL can seem simple at first but it can quickly become complicated. It is common for people to a write SQL query without realizing they are getting an incorrect result returned. This course is designed with
a focus on accuracy and understanding. You will learn how to avoid the common mistakes people make when writing SQL. Not only that.. but you will get a
visual guide to the SQL language by seeing how queries work
step-by-step. This is a complete course which covers all the core skills you need to master the SQL language.
I believe that the best way to learn SQL is by writing lots of SQL. For that reason, this course includes over 80 coding challenges where you get to write SQL queries and create database objects. These challenges are based on
real-world scenarios and are designed for
optimal understanding.
In this course you will learn everything you need to master SQL! Including:
- Get started with SQL Server and SSMS, two of the world's most popular SQL tools
- How to install SQL Server on Windows and Mac-OS computers

- Learn how to do data analysis and data analytics using SQL. Including advanced query techniques
- Start by learning the fundamentals of the relational model and SQL language
- Analyzing data using aggregate functions with the GROUP BY command
- Writing advanced queries with string and date functions
- Learn to use logical operators to add logic flow to your SQL queries
- Learn how to write both self-contained and correlated sub queries
- Learn how to join data by using the different types of JOIN commands
- Learn how to do more advanced joins such as joining more than two tables and joining on multiple columns
- Learn to create tables and integrity constraints
- How to update, insert and delete data
- How to create indexes
- How to make your queries run faster by making them SARGable
- Learn to write advanced SQL such as stored procedures, window functions, and common table expressions
- Bonus section on Database Design - includes data normalization up to and including Boyce-Codd Normal Form.
- and much, much more!
This course is one that puts you in control. Where you get to write SQL throughout the course, instead of watching someone else code. Every section comes with fresh challenges, modeled after real-world tasks and situations.
This comprehensive course allows you to learn at your own pace through an interactive environment. You will start with the basics and soon find yourself writing advanced SQL queries.
Who this course is for:
- Anyone interested in learning SQL or data analysis!
- Those who are interested in working with SQL Server. This course uses Microsoft SQL Server and T-SQL (Microsoft SQL) variant of the SQL language.
