-----------------------------Cryking原创------------------------------ -----------------------转载请注明出处,谢谢!------------------------ 管道函数是一种比较特殊的函数,其返回值为集合类型. 在PL/SQL中,管道函数和表函数.游标一起联合使用能实现一些比较复杂的功能,当和并行处理一起使用时,还能较大的改善性能. 使用示例1: 实现简单的字符串分割,函数参数为常见的VARCHAR2…

一般情况下,编译的时候可能需要加 -g 选项,对于android ndk的-g选项添加请参见android类目下的另一篇文章. 以下文章中的__builtin_return_address() 宏,若要确认它是否在编译器源码中存在,可以在编译器源码中搜索 return_address, 若找到则可以直接使用(不同架构的编译器调用方法可能不同),而且同时也搜索到了需要包含哪些头文件. __builtin_return_address() 宏简单好用,如果只支持层级0,则只有不断的循环用0来找调用者…

Problem E Simple Addition Input: Standard Input Output: Standard Output Let’s define a simple recursive function F (n), where Let’s define another function S (p, q), In this problem you have to Calculate S (p, q) on given value of   p and q.   Input…

Introduction Surprisingly, a topic of named function expressions doesn't seem to be covered well enough on the web. This is probably why there are so many misconceptions floating around. In this article, I'll try to summarize both - theoretical and p…
