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

Sometimes, we need to filter the table to find data that meets certain criteria. To retrieve the data we need, we can add a `WHERE` clause to our `SELECT` statement:

```SQL
SELECT Column1, Column2, Column3
FROM TableSchema.TableName
WHERE [Condition]
```

The condition is a **boolean expression** (a comparison result). Similar to other programming languages,  comparisons in T-SQL are made with the help of comparison operators.
