Article Introduction：Using ORDERBYRAND() to implement random sorting is suitable for small data volumes or temporary requirements, but has poor performance. The problem is that the full table scans and generates random numbers for each row and then sorts it, resulting in extremely low efficiency when queries are large data or high-frequency. Alternatives include: 1. Pre-random numbering; 2. Random ID range sampling; 3. Pagination cache; 4. Maintaining random pools separately. Which method to choose depends on business requirements and data structure.

Article Introduction：This article will introduce how to use JavaScript's Math.random() function to generate random numbers and build a reusable function to apply to various scenarios, such as loading random pictures, random selection of elements from arrays, and generating random colors and letters. , strings, phrases and passwords. Core points: JavaScript's built-in Math.random() function generates pseudo-random floating point numbers between 0 (inclusive) and 1 (not included). To generate a random number greater than 1, just multiply the result by the scale factor. To generate a random integer, use the Math.floor function to round down. To generate random integers within a specific range, simply add the minimum value of the range to the result. This article shows

Article Introduction：To generate random numbers, you can use Python's random module; its core functions include: 1.random.random() generates floating point numbers between 0 and 1; 2.random.randint(a,b) generates random integers in a specified range; 3.random.choice() randomly selects elements from the list; 4.random.shuffle() randomly disrupts the order of the list. This module is suitable for scenarios such as probabilistic simulation and game development, and must be imported before use.
