一些数据库(比如sql Server)允许您禁用页面级锁，以期它不会从行级锁切换到表级锁。
Some databases (such as SQL Server) allow you to disable the page-level locking in hopes that it won't escalate from a row-level lock to a table-level lock.
由于数据库管理器能够确定某一行何时会被修改，因此可以保证数据完整性，同时限制持有锁的时间。
Because the database manager can determine when a row is changed, it can ensure data integrity while limiting the time that locks are held.
数据库管理器通过查看应用程序的锁列表并查找行锁最多的表，来决定对哪些锁进行升级。
The database manager determines which locks to escalate by looking through the lock list for the application and finding the table with the most row locks.
