- Deleting an index entry from index %2 of file %1. 从文件%251的索引%252中删除一个索引项。
- Insufficient disk space to insert the index entry. 磁盘空间不足,不能插入索引项。
- Threshold percentage of block space allowed per index entry. 每个索引条目允许的块空间的阈值百分比。
- The secondary_type_desc column provides the secondary index type. secondary_type_desc列提供辅助索引类型。
- A secondary index in a pair of indexes used to locate a particular file record. The higher or mass index would often be considered the coarse index. 用来查找特定文件记录的一对索引中的第二级索引。高一级的或涉及量大的索引通称为粗索引。
- Dots or dashes in a row leading the eye across a page, as in an index entry. 指引线引导视线掠过书页的成排点或短划线，如在索引词条中
- Type columns, a PATH secondary index may be able to speed up the search. 类型列指定路径表达式,则PATH辅助索引可以提高搜索的速度。
- Build a secondary index on a timestamp column if you want to improve the performance of incremental population. 如果您想改善增量填充的性能,则可在时间戳列上生成一个二级索引。
- If you add a PATH secondary index, you may also improve the search performance in such queries. 如果添加PATH辅助索引,则您还可以改善此类查询的搜索性能。
- Index selectivity refers to the ability of an index to locate a desired index entry without having to read additional data. 索引选择性指的是索引所具备的定位所需索引条目而无需读取额外数据的能力。
- An index entry contains the attributes, passwords and protection attributes, allocation and extent information, and statistics of the index component. 索引项包括其索引部分的属性、口令和保护属性、空间分配信息以及某些统计信息等。
- In the PATH secondary index, the path and node values are key columns that allow efficient seeks when searching for paths. 在PATH辅助索引中,路径值和节点值是用于提高路径搜索效率的键列。
- In the PATH secondary index, the path and node values are key columns that allow for more efficient seeks when searching for paths. 在PATH辅助索引中,路径值和节点值是允许在搜索路径时使用更高效的查找功能的键列。
- This time, our 1 million row index entry has it\'s leading byte value spread across 99 (100 if you include a value for zero) different values, rather than just 4. 这次，我们一百万行的索引项将前导（/起始）字节分摊到99（若包括了0则有100个）个不同的值，而不是仅为4。
- To understand how a secondary index is used, consider what occurs when a user changes the way messages are presented in a messaging folder. 若要了解如何使用辅助索引,请考虑当用户更改邮件在邮件文件夹中的显示方式时所发生的操作。
- This time, our 1 million row index entry has it's leading byte value sdivad across 99 (100 if you include a value for zero) different values, rather than just 4. 这次，我们一百万行的索引项将前导（/起始）字节分摊到99（若包括了0则有100个）个不同的值，而不是仅为4。
- If a tagged column is represented in a secondary index, each distinct occurrence of the column is referenced by the index. 如果在辅助索引中表示一个标记列,则该列每次不同的出现均会通过索引来引用。
- Each table consists of one B-tree that contains the data, although there can be many secondary index B-trees used to provide different views of the data. 尽管可能有许多用于提供不同数据视图的辅助性索引B树,但每个表均由一个包含数据的B树组成。
- It is this binary representation that is used in the index entry when a number column is indexed. 当数字列建立索引时,正是这个二进制表示用于索引项中。
