Student Lab Manual

T-SQL for SQL Server

1

Introduction:

This lab manual is based on the SQL Server 2005 AdventureWorks sample database.

All assignments will use the objects from the AdventureWorks database, and the labs will use the Microsoft SQL Server management Studio as a learning platform.

Each lab will feature a basic assignment and optionally a challenge assignment. You Instructor will review each lab in class and provide example solutions to the challenge assignments.

Learning SQL is a hand-on experience, you are encouraged to explore beyond these basic assignments and ask questions in class.

Before you proceed beyond a specific lab, please ensure you understand the topics being explored and all your questions have been answered.

Enjoy and have fun.
