Cause:An error occurred in a recursively called HHCODE function. Action:This is an internal error. Contact Oracle Support Services. ORA-13005: recursive HHCODE function error是Oracle系统报出的错误。该错误表明在查询SQL语句中,使用了HHCODE函数,而使用的这个HHCODE函数是递归的。HHCODE函数用于从一个XML...
1. SQL Recursive Queries (递归查询)：在Oracle 11g R2及以后版本中，Oracle支持递归公用表表达式（Recursive Common Table Expression, 简称CTE）来进行层次结构查询或递归数据处理。例如，在处理树形结构数据时，可以使用WITH RECURSIVE语句来递归地遍历层级关系。Sql 1-- 假设有如下自关联的员工表，表示员工与其上级的...
All recursive real functions are continuous; in fact all theB-recursive real functions are continuous for any oracleB, simply because Turing machines computing them are finite objects. But simple discontinuous functions such as step functions have to be in some sense "easy" if they have recursive...

However, Turing certainly never used the term “recursion theory” or “recursive function theory” for the subject. Turing mentioned the term “recursive function” only very briefly in [1937b] and [1939, Section 2] to say that these functions were mathematically equivalent to his Turing ...
There is no natural way to find the leaf nodes until the result set is produced, so we use the LEAD analytic function in the main select list to check the next row in the result set. If it has a level that is less than or equal to the current row, we know the current row must...
