| 5. | Because both transactions are converting to exclusive locks , and they are each waiting for the other transaction to release its shared - mode lock , a deadlock occurs
由于两个事务都要转换为排他锁（ x锁） ，并且每个事务都等待另一个事务释放共享模式锁，因此发生死锁。
|
| 6. | If two transactions acquire shared - mode locks on a resource and then attempt to update data concurrently , one transaction attempts the lock conversion to an exclusive lock
如果两个事务获得了资源上的共享模式锁，然后试图同时更新数据，则一个事务尝试将锁转换为排他锁（ x锁） 。
|
| 7. | The shared - mode - to - exclusive lock conversion must wait because the exclusive lock for one transaction is not compatible with the shared - mode lock of the other transaction ; a lock wait occurs
共享模式到排他锁的转换必须等待一段时间，因为一个事务的排他锁与其他事务的共享模式锁不兼容；发生锁等待。
