You probably didn't filter your results

Can we include units used for each variable in the description if they aren't very consistent?

The tests for SQL should expect a function "factorial", not a table of results. There is 0 description about how a table should be returned or how there should be 17 results in the table or what the 17 results should be. Here's the full description of the question:

Do you know recursion?
This is a kata series that you can only solve using recursion.
##1 - Factorial

In mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. For example,

5! = 5 * 4 * 3 * 2 * 1 = 120.

The value of 0! is 1.

#Your task

You have to create the function factorial that receives n and returns n!. You have to use recursion.

hi, cucumber is technically a fruit. "In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering."

Please see the first half of my comment, the issue is not resolved

All the task instruction for SQL is "You have to create the function factorial that receives n and returns n!. You have to use recursion" but the test expects 17 results instead of a function. Even if the test accepts a function as result, including the keywords from the test is still way too difficult for 7 kyu
