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

When there is a relationship between two tables, inserting data becomes less straightforward. A column with a foreign key constraint cannot accept any arbitrary value. It will accept only those values that exist in the referencing column.


## Example

Let’s consider the following example. We have two tables, `Employees` and `Departments`, with the following structure.
