Recursive common table expressions (RCTE).
递归通用表表达式(RCTE)。
The example in Listing 3 shows the creation of structured XML using common table expressions.
清单3中的示例显示了使用公共表表达式创建结构化的XML。
Notice, in lines 45-46, the XML contents placement from the first two common table expressions.
注意,在第45 - 46行中,XML内容来自于最开始的两个公共表表达式。
Common table expressions (the WITH clause) allow efficient pipelining of data-change-operations.
公共表表达式(with子句)允许数据更新操作的高效管道。
Therefore, it might be worthwhile to restructure your spatial query to ensure just a single call to the constructor function using common table expressions.
因此,可能有必要使用公共表表达式重新构造空间查询,以确保只调用一次构造函数。
In this article I provided generic mappings from the Oracle style CONNECT BY recursive query syntax to DB2's standard compliant recursive common table expressions using UNION ALL.
在本文中,我提供了从oracle型CONNECT BY递归查询语法到DB 2中遵从标准的使用UNION ALL的递归公共表表达式的通用映射。
