T-SQL-SPA

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

The `EXISTS` operator lets us check whether a subquery returns any rows. Because no rows are yielded by the subquery as an output when `EXISTS` is used, we can expect a faster subquery performance. There is also the `IN` operator, which lets us check whether a value exists in a given range.

For our examples, we’ll use the tables in the `Match` database.
