About this course
This course is designed to introduce students to Transact-SQL. It is designed for both students requiring the knowledge for other courses in the SQL Server curriculum, and for students preparing for the skills required to take exam 70-761.
The main purpose of the course is to give students a good understanding of the Transact-SQL language which is used by all SQL Server-related disciplines; namely, Database Administration, Database Development and Business Intelligence. As such, the primary target audience for this course is: Database Administrators, Database Developers and BI professionals.
- Working knowledge of relational databases.
- Basic knowledge of the Microsoft Windows operating system and its core functionality.

After completing this course, students will be able to:
Describe key capabilities and components of SQL Server 2016.
Describe T-SQL, sets, and predicate logic.
Write a single table SELECT statement.
Write a multi-table SELECT statement.
Write SELECT statements with filtering and sorting.
Describe how SQL Server uses data types.
Write DML statements.

- Eliminating Duplicates with DISTINCT
- Using Column and Table Aliases
- Writing Simple CASE Expressions
Lab: Writing Basic SELECT Statements
Module 4: Querying Multiple Tables
This module explains how to write queries which combine data from multiple sources in SQL Server. The module introduces the use of JOINs in T-SQL queries as a mechanism for retrieving data from multiple tables.
- Understanding Joins
- Querying with Inner Joins
- Querying with Outer Joins
- Querying with Cross Joins and Self Joins
Lab: Querying Multiple Tables
