Advanced SQL for Microsoft SQL Server Length: 5 Days Prerequisites: SQL syntax: SELECT, INSERT, UPDATE, DELETE: Recommended: " Introduction to Microsoft SQL Server" PRESENTER: Jeffrey Garbus, Author of over 17 books Email: [email protected] Overview Soaring Eagle presents "Advanced SQL Optimization for Microsoft SQL Server," to DBAs, System Administrators and Client Application Developers. Attendees will learn how MS SQL Server processes queries. Learn to identify problematic statements and queries in an application design before they are implemented, saving time and money. Students will estimate query performance on paper and use those estimates to identify implementation issues with queries. This is a performance and tuning class for developers. Key Benefits: When you complete this course you learn how to write efficient SQL Statements, understand when and how to rewrite a query. You will be able to recognize performance issues and understand how stored procedures function.

Audience: Developers and Database Administrators who will be writing queries to be used inside applications.
