Description

The main purpose of this 5 day instructor led 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.

The course will very likely be well attended by SQL power users who aren’t necessarily database-focused; namely, report writers, business analysts and client application developers.

• Lessons
• Using Aggregate Functions
• Using the GROUP BY Clause
• Filtering Groups with HAVING
• Lab : Grouping and Aggregating Data

Module 10: Using Subqueries
