Task: Find strings in a database table that contain at least 5 consecutive letters sorted alphabetically.
SQL requires nested subqueries and CONNECT BY to simulate sequences, while SPL provides direct sequence calculation functions.
In SPL, the string is split into a sequence by character, and the longest substring with consecutive letters in ascending order with a length of 5 or more is selected.
SPL's approach is more straightforward and efficient compared to SQL for this task.
