Row versions that are generated by data modification transactions in a database that uses snapshot or read committed using row versioning isolation levels 由使用已提交读快照隔离或快照隔离级别的数据库中的数据修改事务生成的行版本。
When the read committed snapshot database option is on , read committed transactions provide statement - level read consistency using row versioning Read _ committed _ snapshot数据库选项为on时, read _ committed事务通过使用行版本控制提供语句级读取一致性。
When the read committed snapshot database option is set on , read committed isolation uses row versioning to provide statement - level read consistency 将read _ commited _ snapshot数据库选项设置为on时,已提交读隔离使用行版本控制提供语句级别的读取一致性。
