repeatable read 双语例句
- 1、
The concurrency decreases and data integrity increases when you move the isolation level from uncommitted read ( UR) to repeatable read ( RR).
当隔离级别从未提交读取(UR)移动到可重复读取(RR)过程中,并发性下降,数据集成性提高。 - 2、
Known as repeatable read in DB2, this is the strongest isolation level.
在DB2中称为RepeatableRead,是最强的隔离级别。 - 3、
For instance, if a repeatable read ( RR) scanner has read the partition but not committed yet, detach will wait for the RR scanner to complete before it can make the partition invisible.
例如,如果RepeatableRead(RR)扫描程序已经读取了分区但还没有提交,分离会等到RR扫描程序完成操作后,再使分区不可见。 - 4、
These next key locks are only obtained when the key INSERT finds that a scanner with a repeatable read ( RR) isolation level has a row lock on the next-higher key in the index.
这些nextkey锁只有在keyINSERT发现带有RepeatableRead(RR)隔离级别的扫描器在索引中的next-higher键上有一个行锁时才能获得。 - 5、
Supports table and row level locking and4 isolation levels, RR ( repeatable read), RS ( read stability), CS ( default-cursor stability) and UR ( uncommitted read).
支持表级和行级锁以及4个隔离级别:RR(可重复读)、RS(读可靠)、CS(默认&游标可靠)和UR(未提交读)。 - 6、
If the transaction isolation mode is repeatable read, then the optimizer would base its choice purely on the estimated costs.
如果事务隔离模式是可重复读(RepeatableRead),那么优化器会将其选择完全基于估算成本。 - 7、
This can be used if the isolation level RR ( repeatable read) is not used by any programs that operate on the same set of tables.
如果对同一组表进行操作的任何程序都没有使用隔离级别RR(可重复读,RepeatableRead),那么就可以使用上述操作。 - 8、
Notice that the ANSI isolation levels and DB2 isolation levels have different names, and "repeatable read" has different meanings.
请注意,ANSI隔离级别和DB2隔离级别使用了不同的名称,“可重复的读取”也有着不同的含义。 - 9、
In fact, the only row-level locking that remains during INSERT is the next-key locks that are required to protect an INSERT from adding keys to repeatable read scanners.
实际上,在INSERT期间惟一保持的行级锁是next-key锁,这个锁用于使INSERT不会添加键到可重复的读扫描器。 - 10、
Using the repeatable read isolation level may result in an automatic table lock in some cases.
使用可重复读隔离级别在某些情况下可能会导致自动执行表锁定。 - 11、
Let's first consider repeatable read.
我们先考虑可重复读取。 - 12、
With the "repeatable read" data region fetch requests issued multiple times within the same transaction will always produce the same result yielding better application throughput.
在相同事务下对“可重复读取”区域内数据的多次请求的结果是相同的,但能够带来更好的应用吞吐量。 - 13、
This is an important issue, but using repeatable read isn't the only way to resolve it.
这是一个非常重要的问题,但是使用可重复读取并不是解决问题的唯一途径。 - 14、
This leaves you a choice between read committed and repeatable read.
剩下的也就是在“授权读取”和“可重复读取”之间选择了。 - 15、
Read committed, Read uncommitted, repeatable read, Serializable
提交读,未提交读,可重复读,可串行读
