What is it which can be done in MySQL but not in Oracle?
One notable feature that can be done in MySQL but not in Oracle is the use of the LIMIT clause to restrict the number of rows returned by a query. MySQL allows users to easily specify a limit on the number of results by using LIMIT n, whereas Oracle requires a more complex syntax involving the ROWNUM or FETCH FIRST syntax. Additionally, MySQL supports a simpler way of creating temporary tables that are automatically dropped at the end of a session, while Oracle requires more explicit management of temporary tables.
