To avoid deadlocks in a system, follow these practices: Avoid Circular Wait: Ensure that all processes acquire locks in a fixed, predefined order. Use a Timeout Mechanism: Set timeouts for lock requests to avoid indefinite waiting. Minimize Lock Scope: Hold locks only for the minimum duration needed. Avoid Nested Locks: Reduce or eliminate acquiring multiple locks simultaneously. Use Deadlock Detection: Implement mechanisms to identify and resolve deadlocks when they occur. Prioritize Transactions: Use a priority system to decide which process gets the lock. By implementing these strategies, you can significantly reduce the risk of deadlocks in your system.
Can i bypass a deadlock using WITH (NOLOCK) ? considering dirty read wont be a problem
Sometimes it works but not always as it can also happen on update and update.
Is it possible to know what SQL Query was being executed at the time the deadlock occurred?
From deadlock graph for sure!
