This module is crucial for those new to SQL and T-SQL, as it sets the stage for more advanced topics.
Module 2 – Introduction to T-SQL Querying
This module dives into the core of T-SQL querying. It introduces you to T-SQL, helps you understand sets, and explains the logical order of operations in SELECT statements. Understanding these basics is critical for anyone looking to master querying data with Transact-SQL and sets the foundation for more complex SQL Server queries.
Module 3 – Basic SELECT Queries
Module 3 focuses on writing basic SELECT queries in SQL Server. You’ll learn how to write simple SELECT statements, eliminate duplicates with DISTINCT, and use column and table aliases. This module also introduces you to CASE expressions, which are essential for querying SQL data conditionally.
Module 4 – Querying Multiple Tables
In this module, you’ll explore the intricacies of querying multiple tables in SQL Server. You’ll understand the different types of joins, including inner and outer joins, as well as cross joins and self joins. This knowledge is essential for querying data from multiple tables and understanding the relationships between them.
Module 5 – Sorting and Filtering Data
Module 5 teaches you how to sort and filter data in SQL Server. You’ll learn various techniques for sorting data and filtering it with predicates. The module also covers the use of TOP and OFFSET-FETCH for more advanced data filtering, as well as how to work with unknown values in SQL queries.
Module 6 – Working with SQL Server Data Types
This module focuses on SQL Server data types, particularly date, time, and character data. You’ll learn how to write queries that return these types of data and use specific functions to manipulate them. Understanding SQL Server data types is crucial for effective T-SQL querying and data manipulation.
Module 7 – Using DML to Modify Data
Module 7 introduces you to Data Manipulation Language (DML) in SQL Server. You’ll learn how to insert, update, and delete records using DML commands. This module is essential for anyone who needs to not just query but also modify data in SQL Server.

In this module, you’ll learn about set operators in SQL Server, such as UNION, EXCEPT, and INTERSECT. You’ll also explore the APPLY operator. Understanding set operators is crucial for combining multiple queries into a single query and for advanced T-SQL querying techniques.
Module 13 – Using Window Ranking, Offset, and Aggregate Functions
Module 13 focuses on window functions in SQL Server. You’ll learn how to create windows with the OVER clause and explore various window functions. These functions are essential for advanced data analysis and for querying SQL data in a more sophisticated manner.
Module 14 – Pivoting and Grouping Sets
This module teaches you how to pivot and group data in SQL Server. You’ll learn how to write queries with the PIVOT and UNPIVOT operators and work with grouping sets. These techniques are essential for transforming data and for advanced SQL data analysis.
Module 15 – Implementing Error Handling
Module 15 focuses on error handling in SQL Server. You’ll learn how to implement T-SQL error handling and structured exception handling. Understanding error handling is crucial for writing robust SQL queries and for effective database management.
Module 16 – Managing Transactions
The final module of the course covers transactions in SQL Server. You’ll learn about the database engine’s role in transactions and how to control them. This module wraps up the course by teaching you how to ensure data integrity through effective transaction management.

To improve your skills in T-SQL querying, consider taking a comprehensive T-SQL certification course that covers everything from basic SELECT queries to advanced topics like error handling and transaction management. Hands-on practice is also essential; many courses offer T-SQL online practice exercises to reinforce your learning.
What are the best practices for querying data from multiple tables in SQL Server?
When querying data from multiple tables in SQL Server, it’s crucial to understand different types of joins, such as inner joins, outer joins, cross joins, and self joins. Using the appropriate join can significantly affect the performance and accuracy of your queries. Also, always be mindful of the logical order of operations in your SELECT statements to ensure you get the expected results.
How do I use T-SQL to filter and sort data in SQL Server?
T-SQL offers various ways to filter and sort data. You can use the WHERE clause to filter data based on specific conditions and the ORDER BY clause to sort data. For advanced filtering, you can use the TOP and OFFSET-FETCH clauses. Understanding these T-SQL querying techniques is essential for effective data manipulation in SQL Server.
