Writing Queries Using Microsoft SQL Server 2008 Transact-SQL

This 3-day instructor led course provides students with the technical skills required to write basic Transact-SQL queries for Microsoft SQL Server 2008.

This course is intended for SQL Server database administrators, implementers, system engineers, and developers who are responsible for writing queries.

Obiettivi

After completing this course, students will be able to:

• Describe the uses of and ways to execute the Transact-SQL language.

• Use querying tools.

• Write SELECT queries to retrieve data.

• Group and summarize data by using Transact-SQL.

• Join data from multiple tables.

• Write queries that retrieve and modify data by using subqueries.

• Modify data in tables.

• Query text fields with full-text search.

• Describe how to create programming objects.

• Use various techniques when working with complex queries.

Prerequisiti

Before attending this course, students must have:

• Logical database design.

• Physical database design.

• How data is stored in tables (rows and columns).

• Data integrity concepts.

• Relationships between tables and columns (primary key and foreign key, one-to-one, one-to-many, and many-to-many).

• Basic knowledge of the Microsoft Windows operating system and its core functionality. For example, how to use Windows Explorer, open and save files, and what a client/server application interaction means.
