There are a wide variety of common performance problems that you will encounter when query tuning. Part 2 of this two-part course begins by covering common problems arising from writing and using inefficient Transact-SQL code. You'll then learn about query performance problems and associated query tuning solutions for situations where the query and/or design is inappropriate for the workload type. Finally, the course will cover a variety of more advanced query tuning problem and solutions. The course is very demo-centric, with lots of practical tips and tricks you'll be able to apply in your environment. This course is perfect for developers, DBAs, and anyone responsible for query performance tuning in SQL Server, from SQL Server 2005 onward.
