T-SQL is a dialect of SQL that is used in Microsoft SQL Server. The popularity of Microsoft's database management system sustains high market demand for people well versed in T-SQL. 

This course teaches the core concepts and syntax of T-SQL. First, you will learn how to create tables, insert data, update existing records, and create relationships between tables. Then, you will be exposed to more advanced constructs of T-SQL, like stored procedures, functions, and triggers. 

By the end of the course, you will be sufficiently adept with T-SQL and be able to perform your day-to-day tasks as software and database developers effectively.

Querying Databases Using Transact-SQL

Let’s consider the following table, `ActionPoints`, which tracks the points earned during a game.



In the table above, the column names are:
- `ActionId`: A unique ID that is given to a performed game action.
- `Player`: A player who performed the action.
- `Points`: Points earned for the given action.

# Limitations of aggregate functions

Aggregate functions are helpful, but their primary disadvantage is that row-level details are left out of the output. Using the `AVG()` function, we can, for example, find the average number of points earned for one action:

Learn how to perform aggregation while retaining row-level detail.
