What?! SELECT query caused a deadlock?

deadlockVideoDeadlocks. We all know a lot about them, right? A sample scenario is simple - one process (A) deadlocks with another one (B) when they acquire locks in a different order. A waits on B and B waits on A. One of them has to be killed to resolve the situation. Is that all? Not really. If you work with SQL Server you might have experienced a deadlock when one of the processes was executing a SELECT query and nothing else. It is surprising at the first glance, but actually it makes sense. Watch my video explanation.
