Deadlock) refers to the state in which processes are permanently blocked. SQL can detect deadlocks and terminate a transaction to intervene in the deadlock State. A typical example of A deadlock between two processes is: Obtain lock A in process T1 and apply for lock B; obtain lock B in process T2 and apply for lock A.
