Sometimes, relational tables or sequential files are required to be transformed to XML hierarchical structures, such as XML documents or XML chunks.
表1列出了这些活动的顺序。
一个索引的群集程度;即,表中行的物理顺序与索引的符合程度。
The degree of clustering of an index; that is, the extent to which the physical sequence of rows in a table follows an index.
如果通常是顺序访问大量行(该表可能进行了群集),那么比较大的页大小会更有效。
If typically more rows are accessed sequentially (maybe the table is clustered), then the larger page size is more efficient.
清单2给出了tabscans . sql的代码,它识别拥有最多顺序扫描的表。
Listing 2 shows the code for tabscans.sql, which identifies the tables with the most sequential scans.
访问计划定义按什么顺序访问表,使用哪些索引,以及用何种连接(join)方法来关联数据。
An access plan defines the order for accessing tables, which indexes are used, and by what kind of join methods data is correlated.
请按清单7所示的顺序将字段添加到这个块(这些约束不影响列在表中的顺序—只影响在视图中的顺序)。
Add the fields to this block in the order shown in Listing 7. (These constraints don't affect the order of the columns in the table - just the view.)

In short, you have room for another layer of abstraction here, implemented as two XSLT stylesheets to be applied in sequence.
最后,重分发实用程序的可用性方面也得到了提高,现在可以指定表顺序,并且可以逐个表地停止和继续重分发数据表。
Lastly, the usability aspect of the redistribute utility has improved by allowing you to specify table order and to stop and continue redistributing data table by table.
这意味着DB2按顺序在表空间上提取每一个数据页面到缓冲池。
This means that DB2 fetches every data page in the table space sequentially into the buffer pool.
这说明您可以只提取感兴趣的三个列,还可以使用与数据库中的顺序不同的顺序从表中提取它们。
This demonstrates that you can pull out only those columns of interest, and you can also extract them from the table in a different order than they exist within the database.
作为转换的一部分,优化器还决定正确的表联接顺序,重写表达式,并从SQL中消除任何冗余。
As part of the transformation, the optimizer also determines the correct table join order, rewrites expressions, and eliminates any redundancy from the SQL.
