在 SQL Server 中,这个性能由 timestamp 数据类型提供,它是一个二进制数字,表示数据库中更改的相对顺序。每个数据库都有一个全局当前时间戳值:@@DBTS。每次以任何方式更改带有 timestamp 列的行时,SQL Server 先在时间戳列中存储当前的 @@DBTS 值,然后增加 @@DBTS 的值。如果某 个表具有 timestamp 列,则...
1、 把数据、日志、索引放到不同的I/O设备上,增加读取速度,以前可以将Tempdb应放在RAID0上,SQL2000不在支持。数据量(尺寸)越大,提高I/O越重要. 2、纵向、横向分割表,减少表的尺寸(sp_spaceuse) 3、升级硬件 4、根据查询条件,建立索引,优化 索引、优化访问方式,限制结果集的数据量。注意填充因子要适当(最好...
当第二会话线程执行sql的时候，也需要去访问相同的数据页，它是等待上面的线程将这个数据页读入到缓存中，还是自己再发起一个读磁盘的然后加载到buffer的请求呢？ 代码告诉我们，是前者，等待第一个请求该数据页的线程读入buffer pool。试想一下，如果第一个请求该数据页的线程因为磁盘IO瓶颈，迟迟没...
