SQL ORDER BY RANDOM

The SQL ORDER BY RANDOM clause is used to randomize the order of rows returned in a query result. It is commonly used when selecting random records for testing, sampling, or displaying random content. For example, in PostgreSQL, the query SELECT * FROM table_name ORDER BY RANDOM(); retrieves all rows and arranges them randomly. Similarly, MySQL uses ORDER BY RAND() for the same functionality. While this approach is convenient, it may impact performance on large datasets due to the computation involved in generating random values for each row. It is ideal for small to medium datasets needing randomized results
