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

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

A bug report has been submitted for a bug in Windows version of MySQL that does not use UDF. But It seems to me that I made a mistake, and the MySQL technical support staff gave me the perfect solution to share A moment. Below is the original reply:) Sorry this isn ' t a bug. Below I pasted a sample I did sometime ago for another user: Ok. Assuming you have VC and the source distribution and a server Running I'll create a

Label:Introduction to UDFsOfficial Introduction Please click Http://dev.mysql.com/doc/refman/5.5/en/adding-functions.htmlUDF is an extension of MySQL interface, UDF (UserDefined function) can be translated into user-defined functions, this is used to expand the technical means of MySQL.Background: SELECT COUNT (*) from table;The above count is the internal method of MySQL, but after all, is MySQL's own definition, sometimes does not meet our own needs

The UDF of MySQL is a dynamic Connection Library (* Nix is called a shared library) that does not need to set the entry point ). You can call this method to debug a DLL. Now I will introduce a very simple and easy-to-use debugging method. This method directly utilizes Windows APIs, including language-independent, development tool-independent, and project-type-independent. A typical three-way debugging method is not supported. In addition, the debuggin

The User-Defined Function of MySQL is similar to an API. You can use C/C ++ (or C-language) according to certain specifications) compile a set of functions (udfs), compile them into a dynamic link library, and load and unload udfs using the drop function statement. After a UDF is loaded, it can be called like a built-in MySQL function, and the server automatically loads the existing UDF at startup.Copy code
