In this lesson, we'll examine the syntax and structure of a T-SQL query, covering all the essential clauses and related predicates.

We'll start by exploring the foundational SELECT statement, which retrieves data from SQL Server databases. You'll learn to specify columns, apply functions, and customize your query results using aliases.

Next, we'll delve into the FROM clause, where you'll discover how to specify the tables or views from which to retrieve data. We'll discuss table aliases, joins, and subqueries to efficiently access and combine data from multiple sources.

Then, we'll move on to the WHERE clause, which allows you to filter rows based on specified conditions. You'll learn about logical and comparison operators and how to use predicates like BETWEEN, IN, LIKE, and NULL to refine your query results.

After that, we'll explore the GROUP BY clause, which enables you to group rows into summary sets based on shared values in one or more columns. You'll understand how to use aggregate functions like COUNT, SUM, AVG, MIN, and MAX to perform calculations on grouped data.

Following the GROUP BY clause, we'll cover the HAVING clause, which allows you to filter

grouped rows based on specified conditions. You'll learn how to use aggregate functions in the HAVING clause to refine your grouped results further.

Next, we'll discuss the ORDER BY clause, which sorts the result set returned by a query. You'll discover how to specify ascending and descending sort orders, as well as how to sort by multiple columns and expressions.

Our course includes lessons on creating batch scripts, explaining their use, and how to use them effectively. You'll also learn how to develop and manage stored procedures, enhancing your ability to streamline database operations and improve efficiency.

By the end of this course, you'll have a comprehensive understanding of the syntax and structure of a T-SQL query, along with the skills to create batch scripts, manage stored procedures, and leverage T-SQL querying to retrieve and manipulate data in SQL Server databases. Let's embark on this journey to mastering T-SQL querying together!
