Course Description

This course is an extension of our previous course, "Microsoft SQL for Beginners".  This course, "Microsoft SQL from A to Z" contains all the course material and content from the previous course plus the additional MANY new lectures on more intermediate and advanced-level SQL querying topics.  Students who sign up for this course will also have access to our 150+ page "Complete T-SQL Querying Guide" as an added bonus to assist you in the learning process.

Do you want to learn a skill that can help you earn nearly $100,000 per year? If so, then this course is for you!

SQL (Structured Query Language) is the language we use to interact with databases that store data. This allows us to retrieve data with ease and simplicity. As terms like business intelligence and big data become more familiar, businesses will need more people to learn the SQL language.

This course will teach you how to use the SQL language within Microsoft SQL Server, one of the most popular database engines in the world.

You will have plenty of video lessons to teach you the majority of the content. Each section includes practice problems or additional e-books to help reinforce what you learn in the video tutorials.

The course was well-structured and the explanations were clear overall. I especially appreciated how most concepts were explained using a general format, which made it easier to understand and follow the queries. However, for some important topics like table expressions and CASE statements, a general format was not provided. This made it a bit difficult to fully grasp these concepts, especially for beginners like me who do not have prior SQL knowledge. The practice queries were helpful and served as good refreshers to reinforce learning.

Very patiently described concepts of each SQL Statement Clause! Highly Recommended for building the SQL knowledge and skills from ground up. Although the PDF with SQL Server Installation Guide and Walkthrough needs to be updated.

The teacher did a good job going over the contents of the course, and the practice problems were well related to the material and expanded somewhat upon the concepts that were taught. I'm very happy to have taken this course.

By Chris Schulz on 12/13/2021

An excellent and very thorough introduction to Querying using (T-SQL, the Microsoft version of SQL for Microsoft SQL Server). Be Forewarned.. The instructor has an earlier version of this course (sold separately). Avoid buying that version as this intermediate course also includes all of the material and lessons from the beginner's course.

By Reshma Shriyan on 5/30/2021

Concepts are more clear than what we learn in school. It is only for SQL queries, for in depth DBMS concept you will need some other course, but this is far more sufficient in understanding Joins and how Joins work, Common Table expression, Case, Derived tables etc.

Very concise explanation,depth of analysis and instructor is very patient and empathetic with slow learners like myself.Thank you very much!

By Andrew Limaru on 11/8/2020

A very good course on SQL Server with highly relevant exercises at the end of each chapter. HIGHLY RECOMMENDED!

By Pam Adkins-Smith on 11/8/2020

I learned a lot in this course. The practicing exercises were extremely helpful and the instructor explained things well. I'd definitely recommend this course to anyone interested in learning about SQL. Even those who have worked with it for a while will still learn something. Great course!

By Ryan Murphy on 11/8/2020

I came into this with absolutely no knowledge of Microsoft SQL and now I'm able to build my own queries. Great course.
