For example, reading from a read - only look up table doesn t require repeatable read, and uncommitted read is sufficient.
比如，读取只读的查找表不需要可重复读级别，未提交读级别就足够了。
For example, if one member is updating a row, it would not be proper for another member to read the row with any other isolation level than uncommitted read.
例如，如果一个成员正在更新一行数据，那么另一个成员就不能以未提交读(uncommitted read)以外的任何隔离级别读取这一行。
Supports table and row level locking and 4 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)。
If you have a read-heavy workload, you might want to set isolation to uncommitted read (UR) at the connection level so that you don't have to specify it in each statement.
如果有一个包含大量读取操作的工作负载，那么您可能想将隔离级别设置为未提交读取(UR)，从而不需要在每个语句中设置隔离级别。
Release the row locks so that other applications can SELECT, INSERT, UPDATE, and DELETE from the table (for example, use isolation level cursor stability or uncommitted read).
释放行锁，以便其他应用程序可以对表执行SELECT、INSERT、UPDATE和DELETE(例如，使用游标稳定性(curs or stability)隔离级别或未提交读(uncommitted read)隔离级别)。
The initialization of the split mirror as snapshot performs a crash recovery, rolls back all uncommitted transactions, and makes the database available for any read or write operation.
将分割镜像初始化为快照时，将执行崩溃恢复，回滚所有未提交的事务，并使数据库可以被所有读或写操作访问。
