Debug|mysql 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

Transform feedback is one of the coolest features in OpenGL that allows client applications to get vertex data on the rendering pipeline. Based on this feature, the Z-pass scene decision rendering technology is realized, which is of course not to understand what is the Z-pass scene decision rendering technology, in short, it can effectively reduce the rendering data delivery. This is just a simple example system to understand how transform

The excellent design comes from life, then we start from life, we design a product according to the user life situation, we do not need to cultivate the user's habits, users can use your product for the first time to achieve their goals, and do not need other people's guidance. For example, in the process of designing the first imac, Jonathan and his team traveled to Japan to consult with a person in the Japanese confectionery industry on how to maintain a consistent half transparency while prod

Usability studies show that users can be aware of the response time over a second.Although in the feedback system, when the user needs to wait, the better solution is to adopt a deterministic progress bar. But for some short time consuming, and the user's bandwidth is the main factor, but use loading this low cost implementation feedback. The historical origins of the loading icon have been impossible to e

PHP two-dimensional array deduplication UDF. If we use one-dimensional data to repeat items, we should not say that there are direct functions, but php does not provide functions for two-dimensional data, the following small series will recommend two good two-dimensional arrays to repeat. if we use one-dimensional data to repeat items, we should not say that there is a direct function, but the two-dimensional data php does not provide a function, the

You can specify a parameter as an optional parameter, put it at the end of the parameter list, and specify that its default value is null. An example of an application uses optional parameters to implement a simple price calculation function. Set $ tax as an optional parameter for the user-defined function values. its default value

Php UDF for getting random array list, php Array Paste a piece of code. You don't need to say much about getting random arrays in php. Directly paste the code. The array_rand in php is abnormal. It breaks through normal people's understanding and is tedious.
