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 `WHILE` loop is one of the most straightforward constructs in T-SQL. It is easy and intuitive to use because it works the same as in other programming languages.

# Syntax

The `WHILE` loop executes a block of code while the condition holds.  The syntax for this is:

```SQL
WHILE [Condition]
BEGIN
    [Code to execute]
END
```

# Examples

The `WHILE` loop can be used in a variety of scenarios. Let’s go through some sample cases.

## Printing multiple times

Let’s print a string `10` times using a `WHILE` loop. For that, we need a variable to hold the count, and inside the loop, we increase its value by `1`:
