Do you want to write accurate, effective, and robust T-SQL code? If you want to learn T-SQL the right way, understanding the logic behind the language by learning not only the how but also the why, do not miss this course!
This is your chance to learn T-SQL using practical cases with Itzik Ben-Gan!
- Understand the logic behind T-SQL and thinking in terms of sets.
- Understand Logical Query Processing and its relevance to writing correct and robust T-SQL code.
- Write queries against a single table applying filtering, grouping and sorting of data.
- Write queries against multiple tables using joins, subqueries, APPLY and set-operators.
This course is for you …
- If you are self-taught, or have familiarity with basic relational database concepts and SQL, but do not feel comfortable with T-SQL yet.
- If you want to learn about Itzik’s methodology, using his demo code samples.
- If you need a strong foundation in this field, and you want to learn on your own schedule, from wherever you want, whenever you want, watching the lessons as many times as you need.
What does this course cover?
T-SQL is Microsoft’s dialect of SQL. SQL (Structured Query Language) is a standardized computer language that was originally developed by IBM for querying, altering and defining relational databases, using declarative statements.
This on-demand course provides you with strong foundations, teaching you both about the many T-SQL elements that you need to use when writing queries, and also how to think in SQL, set-based terms. It helps you write accurate, effective, and robust code.
Many SQL intro/fundamentals classes only teach you about the language elements and how to use them, but not about their mathematical roots or why the language elements were designed the way they were designed. This course teaches you both. It emphasizes the unique elements of SQL and the mindset you need to adopt, like thinking in relational terms; thinking of a set as a whole, with no ordering; what the language guarantees and what it doesn’t; common pitfalls and bugs, and best practices to avoid them.
Following this T-SQL Fundamentals course, you will be ready to take our Advanced T-SQL course, if you want to go deeper in this path.

Meet the instructor
Itzik Ben-Gan is a mentor and one of the founders of SolidQ, author of award-winning books about T-SQL (which are considered the standard go-to resource on the topic), a columnist at SQLPerformance.Com, a Microsoft Data Platform MVP since 1999, and a regular speaker in SQL Server-related events.
T-SQL is a very rich and complex scripting language offering you a great degree of flexibility in how you use it. Most programs focus on the graphical user interface as a mechanism for enabling data entry. While you can enter data into SQL Server using GUI-based interfaces, you can manipulate SQL data with Transact-SQL (T-SQL).
Because of this, you can really think of it as a declarative programming language. Avoid the crutch of the GUI entirely and you will benefit from a great deal more functionality and the ability to manipulate the data in your system.
“Itzik’s course opened my eyes and helped me re-discover the passion I have for solving problems using creative and efficient methods.”
“I can see why people love T-SQL. Being able to learn from Itzik has been a pleasure.”
“Excellent. I never thought what else I need to learn more in T-SQL. I never realized there is sucha a deeper world of SQL”
