The exact implementation of this functionality will depend on the implementation of the data model and the transaction semantics of the data model ; whether commit scope is at the cell or row level 此项功能能否完全实现将取决于数据模型的实现以及数据模型的事务语义；还有，提交范围是在单元格级还是行级。
Derby is a 100 - percent java programming language rational database , and offers stored procedures and triggers , row - level locking , can perform transaction commits and roll - backs , and supports encryption Derby是100 %的java编程语言关系数据库，并提供了存储过程和触发器，行级锁定，可以执行事务提交和回退操作，并支持加密。
If the lock escalation attempt succeeds and the full table lock is acquired , then all heap or b - tree , page page , key - range , or row - level locks held by the transaction on the heap or index are released 如果锁升级尝试成功并获取全表锁，将释放事务在堆或索引上所持有的所有堆或b树锁、页锁（ page锁） 、键范围锁（ key锁）或行级锁（ rid锁） 。
Column - level tracking reduces the amount of information that must be sent to the publisher during synchronization , but row - level tracking requires less tracking overhead because more storage is required to track the changes 列级跟踪可以减小在同步过程中必须发送到发布服务器的信息量，而行级跟踪要求较小的跟踪开销，因为它要求更多的存储来跟踪更改。
Serializability may not be implemented using only row - level locks ; there must be another mechanism that prevents a newly inserted row from becoming visible to a transaction that has already executed a query that would return the row 如果仅仅通过“行级锁”是无法实现事务序列化的，必须通过其他机制保证新插入的数据不会被刚执行查询操作的事务访问到。
If the control is not in edit mode , reverts any changes that have been made to the current row if the control is bound to a data source that supports editing or virtual mode has been implemented with row - level commit scope 如果控件未处于编辑模式，那么如果将控件绑定到支持编辑的数据源，或虚拟模式已经以行级提交范围实现，则还原对当前行所做的所有更改。
To support multiple applications accessing the same database at the same time , sql server mobile provides row - level locking of data pages , page - level locking , and isolation levels to help ensure data integrity during concurrency 为支持多个应用程序同时对同一数据库进行访问， sql server mobile提供了数据页行级锁定、页级锁定和隔离级别来帮助确保并发期间的数据完整性。
The simulation result shows that : the performance of the proposed scheme is improved with comparison to pccc and sccc on both awgn channel and the rayleigh fading channel . in awgn channel , it is about same if the snr is low , if the snr is high , the improvement is 0 . 2 ~ 0 . 5db 结果表明：本方案的误码率性能与并行级联码和串性行级联码相比，在高斯白噪声信道上，低信噪比时几乎相同，高信噪比时有0 . 2 0 . 5db的改善。
