udf reader

Hi.baidu.com/isnoMarco IvaldiA few years agoRaptor_udf2.c, Demonstrates how to use the mysql udf to intrude into the system, but this mysql udf also demonstrates a way to call system commands. However, this plug-in is currently not compatible with mysql 5.0 +, mainly because it does not conform to the new mysql udf specifications and does not return results.MySQL

I. Functions: Use the custom functions of MYSQL (I declare again that using MYSQL UDF to escalate permissions is not an overflow, but a function of MYSQL itself ), converts a MYSQL account to a system permission. II. Application scenarios: 1. the target system is Windows (Win2000, XP, Win2003); 2. you already have a user account of MYSQL. This account must have the insert and delete permissions on mysql to create and discard functions (MYSQL document

you can see an interesting application, Turn it off, huh, huh !! 1. definition class myfunction ( note: method must be Public static) Package Com. tgb. jstl; /** * UDF implementation class in the jstl label* */ Public Class Myfunctions { Public Static String sayhello (string name ){ Return "Hello" + name; } } 2.ProvideTLDDescription file,This file can be placed inWEB-INFOr under its Directory.

A php UDF that calculates the remaining time jumps Public function gettime ($ time_s, $ time_n) {$ time_s = strtotime ($ time_s); $ time_n = strtotime ($ time_n); $ strtime = ''; $ time = $ time_n-$ time_s; if ($ time> = 86400) {return $ strtime = date ('Y-m-d H: I: S ', $ time_s);} if ($ time> = 3600) {$ strtime. = intval ($ time/3600 ). 'Hourly '; $ time = $ time % 3600;} else {$ strtime. = '';} if ($ time >=60) {$ strtime. = intval ($ time/60 ).

MySQL's UDF is essentially a dynamic connection library that does not need to set an entry point (*nix is called a shared library). Debugging a DLL can be a personal act. Now let me introduce you to a very simple, easy-to-use debugging method. This approach uses the Windows API directly, language-independent, development-tool-independent, project-type independent, and a typical three-no debugging method. Also, the debugging methods we discussed here s

Spark1.1 introduces the Uer Define function, which allows users to customize the actual UDF needed to process data in spark SQL.Because of the limited functions currently supported by Spark SQL itself, some commonly used functions are not, such as Len, concat...etc but it is very convenient to use UDFs to implement the functions according to business needs.The spark SQL UDF is actually a Scala function, whi
