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 we assign a value of one type to a column that stores data of another type, MS SQL Server tries to perform a conversion and cast the value to the needed type. Let’s consider a table with one column of type `NVARCHAR`:

```SQL
CREATE TABLE ReferenceTable
(
    Data NVARCHAR(100)
);
```

If we try to insert a numeric value into the column above, an automatic conversion to `NVARCHAR` takes place:
