Deadlocks can be very problematic when they occur, especially if you do not know how to figure out what's making the deadlocks occur so that you can take steps to prevent them. This course explains how the locking mechanism in SQL Server works and the circumstances that can lead to deadlocks occurring. The course then describes and demonstrates the various methods for detecting deadlocks in SQL Server and collecting information about the deadlocks so they can be analyzed, plus how to perform deadlock graph analysis using XML, Profiler, Management Studio and third-party tools. Common deadlock scenarios are explained and demonstrated, including lock escalation deadlocks, multi-victim deadlocks, reverse object order deadlocks, and more. The course concludes with how to handle deadlocks in Transact-SQL and ADO.NET code, including the implementation of custom retry logic. This course is perfect for those with no experience of deadlock analysis and those with some experience but who want to solidify their understanding of deadlocks and how to analyze and prevent them. The information in the course applies to all versions from SQL Server 2005 onwards.
