I think it would be better to change the description because:

-If we look at other katas, we see that when it's a "SELECT" statement, it is usually written explicitly or left empty (e.g., 6 kyu - SQL Basics: Simple JOIN and RANK).

-If it's a "FUNCTION" statement, it is typically described clearly (e.g., 5 kyu - Count Weekdays).

Thank you for your quick response! I honestly didn’t expect such a fast reply. 🙂

thanks, Madjosz

There is actually a question at the end. Your code does not account for the "case-insensitive" part.

Just checked and this is written in the initial setup:

-- # write your SQL statement here: you are given a table 'ispalindrome' with column 'str', return a table with column 'str' and your result in a column named 'res'.

Do you think this should be made more clear?

The description is shared across all languages. SQL setup is mostly like this that you have to write a SELECT query.
Normally this is stated in the solution setup. If it is not then indeed this should be added.

I WAS WRITING A SQL FUNCTION like said "Write a function that..."
BUT in the correct answer is no a function, its just a simple select statment.
CHANGE DESCRIPTION
