In this introductory course to Transact-SQL, you will learn about querying a database. This course introduces you to constructing queries using the SELECT statement. This course will show you how to refine your select statements search with various clauses that can be applied to the SELECT statement. This also includes sorting and filtering queries and the method used to do so, along with combining data from different sources within the database. The course opens by introducing you to what SQL and Transact-SQL are.

You will discover the SELECT statement and learn about how it used to create queries and you will learn about the clauses that you can apply to the SELECT statement. You will learn about the various data types that a database can hold as well as learning about working with NULL values in your database.

Next, you will learn further ways of refining your select statement results by removing duplicates and sorting query results. You will then learn about using predicates to refine your query even further and to filter out results that you don’t need. The course will then teach you how to query multiple tables using joins and different types of joins. You will then learn about combining queries using the Intersect and Except queries.

In the end, you will be introduced to functions and aggregating data. In this section, you will learn about scalar functions and logical functions and their respective tasks. You will also study window functions and aggregate functions and applying them to your queries.

Finally, the course will teach you filtering using the GROUP BY sub-clause and the HAVING clause. This course will be of great interest to anyone who wishes to learn about querying a database or would like to learn Microsoft variation of SQL, Transact-SQL.
