Deadlocks strike fear in the hearts of even experienced database administrators. In this session we will walk through an example deadlock and show how to find and interpret the deadlock graph to understand what is happening. We will examine, rate, and test ways to defuse the deadlock. You'll leave the session with an understanding of the questions to ask and avenues to explore the next time you're hit by a deadlock.
Git has become an essential tool for everyone in IT, but many database professionals lag behind and haven't yet learned Git. In this demo-packed session, I'll show you how to learn Git by using GitHub to contribute to Microsoft Documentation. We'll start with an overview of Git and GitHub, then walk through an example of forking a repo, cloning it, creating a branch, committing and pushing a change, and creating a Pull Request.
A community member sent me an interesting question: why would using a temp table cause a stored procedure to slow down dramatically? Why would the procedure use massively more logical reads against a temp table than it does against a user database table? In this session we reproduce the problem, then use built-in tools in SQL Server to diagnose and understand what is happening. We use the results to make a plan to keep the stored procedure fast.
