How to debug a MySQL UDF
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
