Randomizing the Order in Oracle Database

To select a random number of records in Oracle database and randomize the order, you can use the ORDER BY clause in your query along with the RAND() function. For example, to select a random 10 records, you can use:

SELECT * FROM table_name ORDER BY RAND() LIMIT 10;

This query will order the records in a random order and limit the result to 10 records. Each time you run the query, you will get a different set of random records. This method works by generating a random number for each record in the table and then ordering them based on that random number.
