• This means that statistics tied to indexes , which are created with full scan when the index is built , require the whole table scan to be refreshed
  这意味着，对于在生成索引时通过完全扫描创建的索引相关统计信息，将需要刷新整个表扫描。
• A table scan running on node n1 will only fill the memory associated with node n1 unless the scan is being run in parallel on cpus from multiple nodes
  除非在cpu上对多个节点执行并行扫描，否则，对节点n1执行的表扫描仅填充与节点n1关联的内存。
• Because of the number of table scans and table sorts in the tpc - h workload , prefetching data from disks into memory is important for optimal performance
  因为tpc - h工作负载中表扫描和表排序的数量较多，所以为获得最佳性能将数据从磁盘预取到内存是很重要的。
• The locklist and maxlocks would help determine the type of locks that will be held during a certain scan index scan or table scan , along with the isolation level
  Locklist和maxlocks将帮助确定某扫描（索引扫描或表扫描）期间将持有的锁类型，以及隔离级别。
• If the value is set to 0 , then the optimizer chooses index scans over table scans if appropriate indexes exist , without even considering the estimated costs
  如果将其值设置为0 ，那么当存在合适的索引时，优化器就选择索引扫描而非表扫描，甚至不考虑估算成本。
• The first example shows how to force the optimizer to use a nonclustered index to retrieve rows from a table , and the second example forces a table scan by using an index of 0
  优化器提示的两种方式。第一个示例说明如何强制优化器使用非聚集索引检索表中的行，第二个示例使用索引0强制执行表扫描。
• Specifies that the query optimizer use a table scan , one or more indexes , or a locking method with this table or view and for this select , insert , update , or delete statement
  指定查询优化器使用一个表扫描、一个或多个索引，或为当前表或视图以及当前的select 、 insert 、 pdate或delete语句使用锁定方法。
• Now , while printing guarantee slips for clients , staff first scan the original client insurance applications into the image system of the machine , and extract them to the printing servers , so that they can be printed together with formal invoices , company seals , customer - built covers , and pre - designed insurance items . the printed documents are bound into brochures to be handed to clients
  现在，在打印客户投保单时，工作人员将首先把原始的客户保险申请表扫描到机器影像系统，并抽取到打印服务器，以连同正式发票公司印章定制封面封底和预先设定好的各险种条款规定一起打印出来，打印后的资料再通过装订成册提交到客户手中。
• In a quick test on a table with 100 , 000 rows loaded using a sequence , a normal index was used for most queries returning up to 30 rows , as was the reverse key index , however , when the number of rows went up to 1 , 000 , 000 the reverse key index was never used and a full table scan was used every time
  在一个用一个序列载入并含100 , 000行的表上做一个快速的测试，分别用普通索引和逆序索引查询并返回30行数据，当行数增长到1 , 000 , 000 ，将不再使用逆序索引而是每次使用全表扫描。
