The course makes participants familiar with the writing of optimal T-SQL queries. Participants acquire the skills to successfully monitor the T-SQL queries to identify difficult operations, to understand an execution plan, the usage of indexes and statistics. They will get a broader knowledge behind query optimization, like analyzing the causes of slow execution, caused by the query itself or another queries. This course will cover recommended guidelines for writing queries, as well as other alternatives to demanding query processing. Upon successful completion of this course, students will be able to: - Understand how query processing in SQL Server works - Monitor the server for performance and query problems - Analyse the causes of poor query performance - Use indexes properly to make queries much faster - Use full-text indexes for efficient querying of text data - Rewrite queries for more effective execution - Design application processing for performance - Avoid the biggest mistakes by creating and using queries - Describe built-in SQL Server alternatives to demanding query processing
